A base beer enhanced by or featuring the character of additional grain or grains. The specific character depends greatly on the character of the added grains.
Same as base beer style, although some additional haze may be noticeable.
Same as base beer style. The additional grain should be noticeable in flavor, although it may not be necessarily identifiable. However, the alternative grain should provide the major flavor profile for this beer. Different grains have different characters; the additional grain should enhance the flavor of the base beer. Many will add an additional grainy, bready, or nutty flavor.
Same as base beer style. The added grain will lend a particular character, although with some grains the beer will simply seem a bit more grainy or nutty. The alternative grain should provide the major aroma profile for this beer.
Same as the base beer, although many additional grains will tend to increase the body (oats, rye) and increase the viscosity, while some may decrease the body (GF grains) resulting in thinness.
If the alternative grain does not provide a noticeable distinguishable character to the beer, enter it as the base style. This style should not be used for styles where the alternative grain is fundamental to the style definition (e.g., Rye IPA, Oatmeal Stout, Rice- or Corn-based International Lager). Note that sake is not beer, and is not intended for this category.
Throughout history, beer of a somewhat higher alcohol content and richness has been enjoyed during the winter holidays, when old friends get together to enjoy the season. Many breweries produce unique seasonal offerings that may be darker, stronger, spiced, or otherwise more characterful than their normal beers. Spiced versions are an American or Belgian tradition, since English or German breweries traditionally do not use spices in their beer.
Generally ales, although some dark strong lagers exist. Spices are required, and often include those evocative of the Christmas season (e.g., allspice, nutmeg, cinnamon, cloves, ginger) but any combination is possible and creativity is encouraged. Fruit peel (e.g., oranges, lemon) may be used, as may subtle additions of other fruits. Flavorful adjuncts are often used (e.g., molasses, treacle, invert sugar, brown sugar, honey, maple syrup, etc.).
Like a fruit, herb, spice, or wood beer, but sour and/or funky.
