Question: As an American larger, was is the main adjunct used to produce Budweiser?

Context paragraphs:
Still: A still is an apparatus used to distill liquid mixtures by heating to selectively boil and then cooling to condense the vapor.  A still uses the same concepts as a basic distillation apparatus, but on a much larger scale.  Stills have been used to produce perfume and medicine, Water for Injection (WFI) for pharmaceutical use, generally to separate and purify different chemicals, and to produce distilled beverages containing Ethanol.

American lager: American lager or North American lager is pale lager that is produced in North America.  Pale lager originated in Europe in the mid-19th century, and moved to America with German immigrants.  As a general trend outside of Bavaria and the Czech Republic where the beers may be firmly hopped, pale lager developed as a modestly hopped beer, and sometimes used adjuncts such as rice or maize – and this was also true in America.

Scalpelling: Scalpelling is a body art procedure similar to body piercing for the creation of decorative perforations through the skin and other body tissue, and is most commonly used as a replacement for or enhancement of ear piercing.  Whereas piercing is typically performed with a hollow piercing needle or an ear piercing instrument, scalpelling is performed by using a scalpel to cut a slit into the skin.  Unlike dermal punching, no flesh is removed.  The technique can immediately produce holes with a larger diameter than can be achieved by piercing.  This is a more rapid means of accommodating larger gauge jewellery than stretching, a technique whereby piercings are enlarged by inserting gradually larger jewellery.  Scalpelling is performed to quickly achieve a large-gauge piercing, when scar tissue is preventing further stretching, if tissue has thinned to the point where further stretching could cause it to break, or to combine two closely placed piercings into one hole.

Parabolic antenna: A parabolic antenna is an antenna that uses a parabolic reflector, a curved surface with the cross-sectional shape of a parabola, to direct the radio waves.  The most common form is shaped like a dish and is popularly called a dish antenna or parabolic dish.  The main advantage of a parabolic antenna is that it has high directivity.  It functions similarly to a searchlight or flashlight reflector to direct the radio waves in a narrow beam, or receive radio waves from one particular direction only.  Parabolic antennas have some of the highest gains, meaning that they can produce the narrowest beamwidths, of any antenna type.  In order to achieve narrow beamwidths, the parabolic reflector must be much larger than the wavelength of the radio waves used, so parabolic antennas are used in the high frequency part of the radio spectrum, at UHF and microwave (SHF) frequencies, at which the wavelengths are small enough that conveniently-sized reflectors can be used.

Exoenzyme: An exoenzyme, or extracellular enzyme, is an enzyme that is secreted by a cell and functions outside of that cell.  Exoenzymes are produced by both prokaryotic and eukaryotic cells and have been shown to be a crucial component of many biological processes.  Most often these enzymes are involved in the breakdown of larger macromolecules.  The breakdown of these larger macromolecules is critical for allowing their constituents to pass through the cell membrane and enter into the cell.  For humans and other complex organisms, this process is best characterized by the digestive system which breaks down solid food via exoenzymes.  The small molecules, generated by the exoenzyme activity, enter into cells and are utilized for various cellular functions.  Bacteria and fungi also produce exoenzymes to digest nutrients in their environment, and these organisms can be used to conduct laboratory assays to identify the presence and function of such exoenzymes.  Some pathogenic species also use exoenzymes as virulence factors to assist in the spread of these disease causing microorganisms.  In addition to the integral roles in biological systems, different classes of microbial exoenzymes have been used by humans since pre-historic times for such diverse purposes as food production, biofuels, textile production and in the paper industry.  Another important role that microbial exoenzymes serve is in the natural ecology and bioremediation of terrestrial and marine environments.

Produce: Produce is a generalized term for a group of farm-produced crops and goods, including fruits and vegetables – meats, grains, oats, etc. are also sometimes considered produce.  More specifically, the term "produce" often implies that the products are fresh and generally in the same state as where they were harvested.  In supermarkets the term is also used to refer to the section where fruit and vegetables are kept.  Produce is the main product sold by greengrocers, farmers' markets, and fruit markets.  The term "produce" is commonly used in the U.S. but is not typically used outside the agricultural sector in other English-speaking countries.

Lacunarity: Lacunarity, from the Latin lacuna meaning "gap" or "lake", is a specialized term in geometry referring to a measure of how patterns, especially fractals, fill space, where patterns having more or larger gaps generally have higher lacunarity.  Beyond being an intuitive measure of gappiness, lacunarity can quantify additional features of patterns such as "rotational invariance" and more generally, heterogeneity.  This is illustrated in Figure 1 showing three fractal patterns.  When rotated 90°, the first two fairly homogeneous patterns do not appear to change, but the third more heterogeneous figure does change and has correspondingly higher lacunarity.  The earliest reference to the term in geometry is usually attributed to Mandelbrot, who, in 1983 or perhaps as early as 1977, introduced it as, in essence, an adjunct to fractal analysis.  Lacunarity analysis is now used to characterize patterns in a wide variety of fields and has application in multifractal analysis in particular (see Applications).

Bede Aircraft: Bede Aircraft Corporation was founded by controversial aeronautical engineer Jim Bede in 1961 to produce the BD-1 kit aircraft, which eventually became the American Aviation Corporation's AA-1.  The company also created and produced a number of advanced kit planes including the famous Bede BD-5 (pusher propeller driven) and BD-5J (turbojet driven).  The BD-5J has held the Guinness record as the World's Smallest Jet Aircraft for more than a quarter century.  Versions of it saw use in various Budweiser commercials (the Bud Light Jet, which was lost in an inflight fire and crash unrelated to airshow work).  The tiny jet also appeared in two James Bond movies; "Octopussy" starring Sir Roger Moore, and later in a cameo appearance, hanging from the wall of Q's workshop in "Die Another Day" starring Pierce Brosnan as Agent 007.

Budweiser: Budweiser ( ) is an American-style pale lager produced by Anheuser-Busch, currently part of the multinational corporation Anheuser-Busch InBev.  Introduced in 1876 by Carl Conrad & Co. of St. Louis, Missouri, it has grown to become one of the largest selling beers in the United States, and is available in over 80 markets worldwidethough, due to a trademark dispute, does not necessarily do so under the Budweiser name.  It is made with up to 30% rice in addition to hops and barley malt.  Produced in various breweries around the world, Budweiser is a filtered beer available in draft and packaged forms.

Sheffield plate: Sheffield plate is a layered combination of silver and copper that was used for many years to produce a wide range of household articles.  These included buttons, caddy spoons, fish slices, serving utensils, candlesticks and other lighting devices, coffee and tea sets, serving dishes and trays, tankards and pitchers, and larger items such as soup tureens and hot-water urns.  Almost every article made in sterling silver was also crafted by Sheffield makers, who used this manufacturing process to produce nearly identical wares at far less cost.
