Official Rules

Read about the history of Big Brew Day in the Rocky Mountain Region

The Big Brew Day Competition began as a friendly bet between the Weiz Guys Homebrew Club from Loveland, Colorado, and the Liquid Poets Homebrewing Society from Fort Collins, Colorado.  Which club could brew the best beer on Big Brew Day?  The rules for the competition were simple:

All entries had to be the official Big Brew 2023 homebrew recipe provided by the AHA.

All entries would be brewed on Big Brew Day (5/6/2023) at a gathering by the homebrew club.

Each club would brew several batches, and each would hold a club-only competition to select the club’s entry.

Each entry would be entered as a club, not as an individual.

The home brewing community along the Colorado/Wyoming front range are a tightknit group and talk of this competition spread.  Within a couple of weeks, interest had grown, and the competition had expanded from Denver, Colorado to Cheyenne, Wyoming.  The Weiz Guys would host the event, and it was decided if this was to truly be a competition, there needed to be more entries.  The competition was finally expanded to all AHA registered clubs in the Rocky Mountain Region which also included the states of Idaho, Montana, New Mexico and Utah. 

There was a total of 13 entries from 5 separate states.  The entry fee for the competition was $25; however, all entry fees were donated to the winning club’s designated charitable organization.

Winners of the competition were also promised to have their club featured in Zymurgy Magazine, and to receive prizes for all of the club’s AHA members.  BSG sponsored this event and each AHA member of the winning clubs received either (1) full sack of malt or (2) pounds of hops of a single variety from BSG’s portfolio.  https://bsghandcraft.com/
