Question: Recycler Tour was sponsored by the beer that is what percentage alcohol by volume?
Context: Herkenrode Tripel is a Belgian Abbey beer brewed for the Herkenrode Foundation by commercial brewery St. Joseph in Opitter (Bree, Flanders in Belgium).  It is on the market since July 2009.  It has an alcohol by volume percentage of 7%.  In June 2009 the Federation of Belgian Brewers awarded the beer the name and the logo of Recognized Belgian Abbey Beer.  In the Herkenrode Abbey in Hasselt, which was founded in 1182, beer was brewed until the French Revolution in the brewery of the abbey. Miller Lite, also known simply as Lite, is a 4.2% ABV pilsner light beer brand sold by MillerCoors of Milwaukee, Wisconsin, United States.  Miller Lite competes with Anheuser-Busch's Bud Light beer.  The company also produces Miller Genuine Draft and Miller High Life. In brewing, attenuation is the percentage that measures the conversion of sugars into alcohol and carbon dioxide by the fermentation process; a more attenuated beer will generally be drier and more alcoholic than a less attenuated beer made from the same wort.  The percentage is calculated by comparing weight or specific gravity of the extract before and after fermentation. The Recycler Tour was a concert tour by American rock band ZZ Top.  Presented by Beaver Productions and sponsored by Miller Lite, the tour took place in North America and Europe.  The set list featured material from the band's previous seven studio albums.  Venues were mostly arenas. Beer bread can be a simple quick bread or a yeast bread flavored with beer.  Both beer and bread have a common creation process: yeast is used to turn sugars into carbon dioxide and alcohol.  In the case of bread a great percentage of the alcohol evaporates during the baking process. Lion Red is a New Zealand lager-style beer brewed by Lion Breweries, part of the Lion Nathan group.  The beer is 4.0% alcohol.  Because of its relatively low alcohol content it is widely regarded as an excellent 'session' beer, that is, a beer that can be consumed freely over a long session of time without all the adverse effects of a higher alcohol volume beer.  As such, it is also a favourite of university students, along with similar strength beers such as Speights and DB Draught. Alcohol proof is a measure of the content of ethanol (alcohol) in an alcoholic beverage.  The term was originally used in the United Kingdom and was equal to about 1.75 times the alcohol by volume (ABV).  The UK now uses the ABV standard instead of alcohol proof.  In the United States, alcohol proof is defined as twice the percentage of ABV. The alcohol industry is the commercial industry involved in the manufacturing, distribution, and sale of alcoholic beverages.  The industry has been criticised in the 1990s for deflecting attention away from the problems associated with alcohol use.  The alcohol industry has also been criticised for being unhelpful in reducing the harm of alcohol.  The World Bank works with and invests in alcohol industry projects when positive effects with regard to public health concerns and social policy are demonstrated.  Alcohol industry sponsored education to reduce the harm of alcohol actually results in an increase in the harm of alcohol.  As a result, it has been recommended that the alcohol industry does not become involved in alcohol policy or educational programs.  In the UK the New Labour government took the view that working with the alcohol industry to reduce harm was the most effective strategy.  However, alcohol-related harm and alcohol abuse increased.  The alcohol industry has been accused of using similar tactics as the pharmaceutical industry to exaggerate the health benefits of alcohol which is regarded as a potentially dangerous recreational drug with potentially serious adverse effects on health. Karlovačko is a popular beer in Croatia and Bosnia-Herzegovina.  It is the signature product of brewer Karlovačka Pivovara, located in the city of Karlovac.  It has an alcohol content of about 5.4 percent by volume.  Its makers describe it as "golden-yellow" in color and "refreshingly" bitter in taste.  It won a 2005 Brewing Industry International Award golden medal in the category of beers with 4.5 to 5.5 percent alcohol.  Pictured here in a brown bottle, Karlovačko is now sold in green bottles (also in cans and plastic packaging).  A new era of the brewery business, then called the Karlovačka pivovara, began on 1 April 2003.  That was when HEINEKEN, the most international brewer, became the owner of the brewery.  As a successful and significant part of the HEINEKEN company, Karlovačka pivovara took the name Heineken Hrvatska d.o.o. on 10 December 2014.  In its portfolio Heineken Hrvatska has top-level products that will satisfy the tastes of adult beer lovers on various occasions.  Besides Karlovačko beer, the family of beer also includes: Karlovačko 0.0% Maxx, Karlovačko Limun Natur Radler, Karlovačko Laganini Natur Radler, Karlovačko Leđero Natur Radler, Karlovačko nepasterizirano Retro and Karlovačko crno.  They also have international brands such as Heineken, Amstel Premium Pilsener, Edelweiss Snowfresh, Desperados, Affligem, cider No 1 in the world - Strongbow and Stari lisac, local cider.  In their portfolio there are also Laško Zlatorog, Laško Special beers in three flavors and Union Radler grapefruit. Weyerbacher Brewing Company is a brewery in Easton, Pennsylvania, United States, founded in 1995 by Dan and Sue Weirback.  The brewery is well known for its "huge taste" beers.  Most of their brews are high in alcohol, with QUAD clocking in at 11.8% alcohol by volume, and a one-off 10th anniversary ale called Decadence brewed to 13% alcohol by volume.  Hops Infusion is one of the bitterest examples of the IPA style.  Weyerbacher is also a pioneer of aging beer in wooden barrels previously used for aging bourbon.  This process was used to transform Old Heathen imperial stout into Heresy, Blithering Idiot barley wine into Insanity, Merry Monks Belgian tripel into Prophecy, and QUAD Belgian quadrupel into Blasphemy.  These four styles are all very high-alcohol brews with complex flavor profiles; the barrel-aging lends additional oak and whiskey flavors.  The results have been widely praised by fans of huge beers, though persons accustomed to more mainstream beer may find them an acquired taste.
