Big Batch Brew Bash

The Big Batch Brew Bash is the KGB's signature homebrew competition. Started in 1996, it has grown into the largest single-style homebrew competition in the history of humankind. Impressive, but don't ask for documentation or a certificate from the world record folks at Guinness. It is also noted for being sanctioned by the American Homebrewers Association and free to enter.

Any homebrewer can enter up to two beers in the BBBB. They will be evaluated by BJCP-associated judges and fully annotated score-sheets will be returned to the brewer.


The Next Big Batch: TBD: 2021

Deadline to Enter: TBD

The 2020 style will follow the Amended Great American Beer Festival (GABF) Section 10: Coffee Beer:

10. Coffee Beer Color: Pale to black depending on the underlying style Clarity: Clear to hazy is acceptable Perceived Malt Aroma & Flavor: Medium-low to medium malt sweetness provides balance with coffee flavor and aroma Perceived Hop Aroma & Flavor: Low to high depending on the underlying style Perceived bitterness: Varies with underlying style Fermentation Characteristics: Typical of underlying style Body: Reflective of the underlying beer style 7 Additional notes: Coffee beers incorporate coffee in any form. Coffee character should be apparent as the defining attribute of this category, ranging from subtle to intense, and should be in harmony with other attributes of the underlying beer. Other flavors arising from the use of flavored coffee may also be present. Within the framework of these competition guidelines, stouts and porters made with coffee are entered elsewhere. To allow for accurate judging the brewer must list details about the coffee(s) used, and any other ingredients or processes used ("medium roast cold extract in bright tank" for example). The brewer must also indicate the classic or experimental ale or lager style of the underlying base beer; the brewer may indicate "no classic style" in instances where the base beer does not hew to a category within these competition guidelines. Beer entries not accompanied by this information will be at a disadvantage during judging. Original Gravity (°Plato) Varies with style • Apparent Extract/Final Gravity (°Plato) Varies with style • Alcohol by Weight (Volume) Varies with style • Hop Bitterness (IBU) Varies with style • Color SRM (EBC) Varies with style

Official entry forms and drop off locations are located on the Competition News page.
