[Docket No. TTB-2023-0006; Notice No. 224]
RIN 1513-AD02
 AGENCY: Alcohol and Tobacco Tax and Trade Bureau, Treasury.
 ACTION: Notice of proposed rulemaking.
 SUMMARY: The Alcohol and Tobacco Tax and Trade Bureau (TTB) proposes establishing the approximately 2,186,689 acre “Upper Cumberland” viticultural area in Middle Tennessee. The proposed viticultural area is not within any other established viticultural area. TTB designates viticultural areas to allow vintners to better describe the origin of their wines and to allow consumers to better identify wines they may purchase. TTB invites comments on this proposed addition to its regulations.
 DATES: Comments must be received by October 30, 2023.

SUPPLEMENTARY INFORMATION: Background on Viticultural Areas TTB Authority Section 105(e) of the Federal Alcohol Administration Act (FAA Act), 27 U.S.C. 205(e), authorizes the Secretary of the Treasury to prescribe regulations for the labeling of wine, distilled spirits, and malt beverages. The FAA Act provides that these regulations should, among other things, prohibit consumer deception and the use of misleading statements on labels and ensure that labels provide the consumer with adequate information as to the identity and quality of the product. The Alcohol and Tobacco Tax and Trade Bureau (TTB) administers the FAA Act pursuant to section 1111(d) of the Homeland Security Act of 2002, codified at 6 U.S.C. 531(d). In addition, the Secretary of the Treasury has delegated certain administrative and enforcement authorities to TTB through Treasury Order 120-01. Part 4 of the TTB regulations (27 CFR part 4) authorizes TTB to establish definitive viticultural areas and regulate the use of their names as appellations of origin on wine labels and in wine advertisements. Part 9 of the TTB regulations (27 CFR part 9) sets forth standards for preparing and submitting petitions to establish or modify American viticultural areas (AVAs) and lists the approved AVAs. Definition Section 4.25(e)(1)(i) of the TTB regulations (27 CFR 4.25(e)(1)(i)) defines a viticultural area for American wine as a delimited grape-growing region having distinguishing features as described in part 9 of the regulations and, once approved, a name and a delineated boundary codified in part 9 of the regulations. These designations allow vintners and consumers to attribute a given quality, reputation, or other characteristic of a wine made from grapes grown in an area to the wine's geographic origin. The establishment of AVAs allows vintners to describe more accurately the origin of their wines to consumers and helps consumers to identify wines they may purchase. Establishment of an AVA is neither an approval nor an endorsement by TTB of the wine produced in that area. Requirements Section 4.25(e)(2) of the TTB regulations (27 CFR 4.25(e)(2)) outlines the procedure for proposing an AVA and allows any interested party to petition TTB to establish a grape-growing region as an AVA. Section 9.12 of the TTB regulations (27 CFR 9.12) prescribes standards for petitions to establish or modify AVAs. Petitions to establish an AVA must include the following: Evidence that the area within the proposed AVA boundary is nationally or locally known by the AVA name specified in the petition;
                An explanation of the basis for defining the boundary of the proposed AVA;
                A narrative description of the features of the proposed AVA affecting viticulture, such as climate, geology, soils, physical features, and elevation, that make the proposed AVA distinctive and distinguish it from adjacent areas outside the proposed AVA;
                The appropriate United States Geological Survey (USGS) map(s) showing the location of the proposed AVA, with the boundary of the proposed AVA clearly drawn thereon; and
                A detailed narrative description of the proposed AVA boundary based on USGS map markings. Upper Cumberland Petition TTB received a petition from the Appalachian Region Wine Producers Association, proposing the establishment of the “Upper Cumberland” AVA. The proposed Upper Cumberland AVA covers all or portions of the following eight counties in Middle Tennessee: Cumberland, Fentress, Macon, Putnam, Overton, Smith, Warren, and White. The proposed AVA contains approximately 2,186,689 acres, with 55 vineyards totaling over 71 acres spread throughout the proposed AVA. There are also nine wineries within the proposed AVA. According to the petition, there is at least one vineyard in each of the counties within the proposed AVA, demonstrating that commercial viticulture and winemaking take place throughout the entire proposed AVA. According to the petition, the distinguishing features of the proposed Upper Cumberland AVA include its geology and elevation, soils, and climate. Unless otherwise noted, all information and data pertaining to the proposed AVA is from the petition and its supporting exhibits. Name Evidence The proposed Upper Cumberland AVA is located within the watershed of the Cumberland and Tennessee Rivers or their tributaries, which traditionally includes a total of 14 counties. The proposed Upper Cumberland AVA originally included all 14 of these counties. However, at the request of TTB, the petitioners agreed to exclude those counties that currently lack commercial viticulture, leaving eight counties within the proposed AVA. TTB notes that petition included evidence that the six excluded counties have the same distinguishing features as the remaining eight counties. If the proposed Upper Cumberland AVA is established, TTB may consider future petitions to modify the boundary of the AVA if commercial viticulture develops in those six excluded counties. The petition includes a map produced by the Upper Cumberland Tourism Association titled “Upper Cumberland Tennessee.” [1]
                    
                     The map includes the counties that are entirely or partially within the proposed Upper Cumberland AVA. The maps also show several Tennessee towns that are within the proposed AVA, including Lafayette, Cookeville, Crossville, and McMinnville. The petition included a web page from another tourism site that bears the title “Welcome to Tennessee's Upper Cumberland” and encourages readers to click links to learn more information about the “friendly Chambers of Commerce in The [sic] Upper Cumberland Counties.” [2]
                    
                     The counties listed as the “Upper Cumberland Counties” include the eight counties that are located within the proposed AVA. A website dedicated to forecasting the weather of the region of the proposed AVA is called “Upper Cumberland Weather.” [3]
                    
                     The Upper Cumberland Medical Society “supports personal leadership development of physicians from any of the 14 counties of Upper Cumberland.” [4]
                    
                     The 14 counties listed by the society include the counties that are within the proposed AVA. The Upper Cumberland Development District provides an array of services to individuals, businesses, and communities within the proposed 
                    ( print page 59484)
                    AVA through a variety of organizations, including the Upper Cumberland Area Agency on Aging and Disability.[5]
                    
                     A web page for the 2019 Senior Olympics provides information about events in the “Upper Cumberland District,” which also includes all the counties within the proposed AVA.[6]
                    
                     Finally, the Upper Cumberland Genealogical Society serves residents within the proposed AVA.[7] Boundary Evidence According to the petition, Tennessee is divided into three main regions: East, Middle, and West. The proposed Upper Cumberland AVA is located entirely within the Middle region, within the watershed of the Cumberland River and its tributaries, as well as a small portion of the Tennessee River watershed. Middle Tennessee includes the western portion of the Cumberland Plateau, the Eastern Highland Rim, and the Inner and Outer Central Basin land regions. The proposed Upper Cumberland AVA encompasses portions of each of these regions, specifically the western portion of the Cumberland Plateau, the Eastern Highland Rim and the eastern portion of the Outer Central Basin. The Tennessee-Kentucky State line forms the northern boundary of the proposed AVA in order to exclude areas not traditionally or currently associated with the name “Upper Cumberland.” The remaining boundaries largely follow county lines to exclude counties associated with the name “Upper Cumberland” that do not contain commercial viticulture, as well as any counties that are not associated with the name “Upper Cumberland” and have geological and climatic differences, which will be discussed in detail later in this document. Distinguishing Features The distinguishing features of the proposed Upper Cumberland AVA include its geology and elevation, soils, and climate. Geology and Elevation The proposed Upper Cumberland AVA encompasses portions of three distinct geographic regions. The eastern portion of the proposed AVA is located on the western portion of the Cumberland Plateau. This region was formed from layers of sedimentary rocks, including sandstone, limestone, and shale, that were deposited when an ancient ocean covered the area. As the North American and African protocontinents came together, the sediment and rock stuck between them and the region of what is now the proposed AVA was uplifted, forming the Cumberland Plateau. Average elevations within this portion of the proposed AVA range from 1,500 to 1,800 feet. The middle portion of the proposed Upper Cumberland AVA is located on the Eastern Highland Rim. The Eastern Highland Rim is a cuesta, which is a ridge where a harder sedimentary rock overlies a softer layer, with the whole ridge being tilted somewhat from the horizontal. The bedrock of the middle portion of the proposed AVA is comprised primarily of Mississippian-aged St. Louis and Warsaw limestones with Fort Payne chert underlain by Chattanooga shale. Elevations within this portion of the proposed AVA range from 600 to 1,000 feet. The western portion of the proposed AVA lies on the Outer Central Basin. This region is mostly an escarpment, which the petition defines as a long, steep slope, especially one at the edge of a plateau or a slope separating areas of land at different heights. Underlying rocks in this region are limestone, chert, and shale. The Outer Central Basin gradually descends to the lower, flatter elevations of the Inner Central Basin, which is not within the proposed AVA. The petition did not include a range of elevations for this portion of the proposed AVA but noted that the elevations are higher than the average elevations of the Inner Central Basin region, located to the west. According to the petition, the uplifted elevations of the proposed AVA allow vineyards to receive more direct and concentrated sunlight—the level of UV rays increases between 10 and 20 percent for every 1,000 feet of elevation—than vineyards at lower elevations. As a result of the greater levels of UV rays, grapes develop thicker skins, which increases the color concentration and tannins in the resulting wines. To the north and south of the proposed AVA are continuations of the same geological features found within the proposed AVA. These areas were excluded from the proposed AVA primarily because they are not considered to be part of the region known as “Upper Cumberland.” The petition did not provide information on elevations within the regions to the north and south of the proposed AVA. To the east of the proposed AVA is the Valley and Ridge Province of Tennessee, where the sediment and rock was folded and faulted by the collision of the ancient protocontinents, rather than being uplifted into a plateau. Elevations in the Valley and Ridge Province range from 1,100 to 1,500 feet in the ridges and from 700 to 1,000 feet in the valleys. To the west of the proposed AVA is the Inner Central Basin region, which formed when the collision of the continental plates pushed the sediment and rock into a bulging dome. Over time, the dome eroded and became lower and flatter. When the overlying rocks eroded, the softer underlying limestone began to erode quickly, forming a basin. Elevations within the Inner Central Basin are 300 to 400 feet lower than elevations within the adjacent Eastern Highland Rim portion of the proposed AVA. Soils According to the petition, the soils of the proposed Upper Cumberland AVA differ according to the physiographic region. Soils of the eastern portion of the proposed AVA, within the Cumberland Plateau region, are from the Inceptisols and Ultisols soil orders. Ultisols are defined as “strongly leached, acid forest soils with relatively low fertility.” Inceptisols “exhibit minimal horizon development” and “lack features characteristic of other soil orders.” They are often found in mountainous regions. The petition describes the soils as moderately deep, dominantly well-drained, and strongly acidic. They have a mesic soil temperature regime, meaning that soil temperatures at a depth of 20 inches generally range from 47 to 59 degrees Fahrenheit (F). The soils also have an udic soil moisture regime, meaning that water moves down through the soil at some time in most years, and the amount of soil moisture plus rainfall is approximately equal to or exceeds the amount of evapotranspiration. The middle portion of the proposed AVA, within the Eastern Highland Rim region, has soils of the Ultisols and Inceptisols soil orders, as well as Alfisols soils. Alfisols soils are moderately-leached soils with relatively high native fertility. Soils in this region are in the udic soil moisture regime and are also predominantly in the thermic soil temperature regime, meaning that soil temperatures at a depth of 20 inches range from 59 to 72 degrees F. The petition describes the soils of this region of the proposed AVA as moderately-to-very deep, moderately well-drained, and loamy or clayey.
                    ( print page 59485) The western portion of the proposed AVA, within the Outer Central Basin region, also has Ultisols, Inceptisols, and Alfisols soils. The soils have a thermic soil temperature regime and udic soil moisture regime, similar to portion of the proposed AVA that is within the Eastern Highland Rim region. According to the petition, the acidic soils of the proposed Upper Cumberland AVA generally have better nutrient balance for vine growth than alkaline soils. The well-drained soils of the proposed AVA also provide the vines with enough water to thrive, but not so much that the roots become waterlogged and more prone to disease and rot. The petition also states that the characteristics of the proposed AVA's soils allow grapes to retain acidity as they ripen, resulting “brighter, more acidic finished wines.” To the north and south, the soils are similar to those within the proposed AVA. To the east of the proposed AVA, within the Valley and Ridge Province, the soils are almost exclusively Ultisols soils. The soils generally have a thermic soil temperature regime and an udic soil moisture regime. To the west of the proposed AVA, in the Inner Central Basin region, the soils include Mollisols, which are not found in the proposed AVA. Mollisols soils are found in grassland ecosystems and are characterized by a thick, dark surface horizon. The Inner Central Basin also does not contain as many Ultisols soils as the proposed Upper Cumberland AVA. Climate The petition provided data on the average maximum and minimum annual temperatures, growing season mean temperatures, growing season length, growing degree days [8]
                    
                     (GDDs), USDA plant hardiness zones, and annual precipitation amounts for the proposed Upper Cumberland AVA and the surrounding regions. The data came from the PRISM Climate Group [9]
                    
                     and was calculated using 1981-2010 climate normals, the most recent climate normals data available at the time the petition was drafted. The following tables summarize the climate data from the petition. Table 1—Average Maximum and Minimum Annual and Average Mean Growing Season Temperatures

 According
                    
                     to the petition, the climate of the proposed Upper Cumberland AVA is suitable for growing a wide variety of wine grapes, including 
                    *vinifera,*
                     hybrid, native, and muscadine varietals, which are all currently growing within the proposed AVA. Bud break generally occurs from the second week of April through the second week of May, and harvest generally occurs from the last week of July through the end of August. Summary of Distinguishing Features In summary, the geology and elevation, soils, and climate of the proposed Upper Cumberland AVA distinguish it from the surrounding regions. The proposed AVA contains portions of three of the major geographic features of Tennessee: the Cumberland Plateau, which is an uplifted region of sandstone, limestone, and shale with elevations between 1,500 and 1,800 feet; the Eastern Highland Rim, a slightly-tilted cuesta of limestone, chert, and shale with elevations between 600 and 1,000 feet; and the Outer Central Basin, an escarpment of limestone, chert, and shale that has elevations that are typically 300 to 400 feet higher than in the adjacent Inner Central Basin region. Soils within the proposed AVA consist of Inceptisols, Ultisols, and Alfisols that are generally well-drained, acidic, and moderately-to-strongly leached. The average growing season length is 212 days, with a mean growing season temperature of 67.5 degrees F and USDA Plant Hardiness Zones ranging from 6b to 7a. GDD accumulations range from 3,134.4 to 4,226.2, and Winkler Regions range from Zone III to Zone V. The average annual precipitation amount is 50.02 inches. To the north and south of the proposed AVA, the geology, elevations, and soils are similar to those of the proposed AVA. However, these areas were excluded because they are not part of the region that is known as “Upper Cumberland.” The region to the south also has a generally warmer climate, with a mean growing season temperature of 69.8 degrees F, a 242-day growing season, USDA Plant Hardiness Zones ranging from 7a to 7b, and 
                    ( print page 59487)
                    regions in Winkler Regions IV and V. The region to the south also has higher annual precipitation amounts. To the east of the proposed AVA is the Valley and Ridge Province, which is comprised of folded and faulted rocks and sediments and has elevations from 700 to 1,000 feet in the valleys and 1,100 to 1,500 feet in the ridges. Soils in this region are almost exclusively Ultisols. The mean growing season temperature and USDA Plant Hardiness Zones are similar to that of the proposed AVA, but the growing season is slightly shorter, and GDD accumulations are slightly lower. Annual precipitation amounts are also higher in the region to the east of the proposed AVA. To the west of the proposed AVA is the Inner Central Basin, which was formed by the erosion of a large, bulging dome of sediment and rocks. Soils in this region include Molisols, which are not found in the proposed AVA, and fewer Ultisols than the proposed AVA. The region is categorized as a Winkler Region V, with a higher mean growing season temperature than the proposed AVA and a USDA Plant Hardiness Zone rating of 7a. Due west of the proposed AVA, the growing season is shorter, but the regions to the northwest and southwest have longer growing seasons. Average annual precipitation amounts are also higher to the west of the proposed AVA. TTB Determination TTB concludes that the petition to establish the proposed Upper Cumberland AVA merits consideration and public comment, as invited in this notice of proposed rulemaking. Boundary Description See the narrative description of the boundary of the petitioned-for AVA in the proposed regulatory text published at the end of this proposed rule. Maps The petitioner provided the required maps, and TTB lists them below in the proposed regulatory text. You may also view the proposed Upper Cumberland AVA boundary on the AVA Map Explorer on the TTB website, at 
                    *https://www.ttb.gov/​wine/​ava-map-explorer*. Impact on Current Wine Labels Part 4 of the TTB regulations prohibits any label reference on a wine that indicates or implies an origin other than the wine's true place of origin. For a wine to be labeled with an AVA name, at least 85 percent of the wine must be derived from grapes grown within the area represented by that name, and the wine must meet the other conditions listed in § 4.25(e)(3) of the TTB regulations (27 CFR 4.25(e)(3)). If the wine is not eligible for labeling with an AVA name and that name appears in the brand name, then the label is not in compliance and the bottler must change the brand name and obtain approval of a new label. Similarly, if the AVA name appears in another reference on the label in a misleading manner, the bottler would have to obtain approval of a new label. Different rules apply if a wine has a brand name containing an AVA name that was used as a brand name on a label approved before July 7, 1986. See § 4.39(i)(2) of the TTB regulations (27 CFR 4.39(i)(2)) for details. If TTB establishes this proposed AVA, its name, “Upper Cumberland,” will be recognized as a name of viticultural significance under § 4.39(i)(3) of the TTB regulations (27 CFR 4.39(i)(3)). The text of the proposed regulation clarifies this point. Consequently, wine bottlers using the name “Upper Cumberland” in a brand name, including a trademark, or in another label reference as to the origin of the wine, would have to ensure that the product is eligible to use the AVA name as an appellation of origin if TTB adopts this proposed rule as a final rule. Public Participation Comments Invited TTB invites comments from interested members of the public on whether it should establish the proposed Upper Cumberland AVA. TTB is also interested in receiving comments on the sufficiency and accuracy of required information submitted in support of the petition. Please provide specific information in support of your comments. Because of the potential impact of the establishment of the proposed Upper Cumberland AVA on wine labels that include the term “Upper Cumberland” as discussed above under Impact on Current Wine Labels, TTB is particularly interested in comments regarding whether there will be a conflict between the proposed AVA name and currently used brand names. If a commenter believes that a conflict will arise, the comment should describe the nature of that conflict, including any anticipated negative economic impact that approval of the proposed AVA will have on an existing viticultural enterprise. TTB is also interested in receiving suggestions for ways to avoid conflicts, for example, by adopting a modified or different name for the proposed AVA.

Regulatory Flexibility Act TTB certifies that this proposed regulation, if adopted, would not have a significant economic impact on a substantial number of small entities. The proposed regulation imposes no new reporting, recordkeeping, or other administrative requirement. Any benefit derived from the use of a viticultural area name would be the result of a proprietor's efforts and consumer acceptance of wines from that area. Therefore, no regulatory flexibility analysis is required. Executive Order 12866 It has been determined that this proposed rule is not a significant regulatory action as defined by Executive Order 12866. Therefore, no regulatory assessment is required.

                         (Berkeley: University of California Press, 1974), pages 61-64. In the Winkler climate classification system, annual heat accumulation during the growing season, measured in annual Growing Degree Days (GDDs), defines climatic regions. One GDD accumulates for each degree Fahrenheit that a day's mean temperature is above 50 degrees F, the minimum temperature required for grapevine growth. The Winkler scale regions are as follows: Region Ia: 1,500-2,000 GDDs; Region Ib: 2,000-2,500 GDDs; Region II: 2,500-3,000 GDDs; Region III: 3,000-3,500 GDDs; Region IV: 3,500-4,000 GDDs; Region V: 4,000-4,900 GDDs.
