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/

2024 Winners
1st Place: Hetch Hetchy Hop Heads, Redwood City, CA
Charity: American Cancer Society

The Hetch Hetchy Hop Heads were established in the early 1990s on the mid-peninsula of the San Francisco Bay Area. The name is derived from the Hetch Hetchy reservoir situated within the Yosemite Valley, which is replenished by pure snowmelt from the Sierra Nevadas. This water, devoid of virtually any minerals, serves as an ideal medium for the brewing of various styles of beer. The goal of the club is to further the hobby of homebrewing through community and friendship. Club members played an important role in the formative years of the Northern California Homebrew Festival (NCHF) filling both the role of chair and serving on the board of directors. The club’s size has fluctuated over time, but a small core group remains. Even those members that have relocated outside of the area continue to return annually to NCHF to rejoin their fellow Hop Heads, where their booth will be serving homebrew late into the evening.
2nd Place: Ozark Zymurgist, Rogers, AZ
Charity: Sheep Dog Impact Assistance
The Ozark Zymurgists is a club of homebrewers that meet the first Tuesday of every month, we typically meet at one of these locations: New Province Brewing, GOAT LAB Brewery, or Black Howler Beer CO which are three great breweries in the heart of the Ozarks. Our mission is to have fun while educating about the science and art of brewing your own beers, ciders, wines, and even fermented foods. We love using our homebrews to make our community a better place. You’ll find us pouring our hearts and hops into local events like The Great Southern Beer Festival and Downtown Rogers Oktoberfest, plus a heap of other shindigs all over the Ozarks. We’re proud to call Northwest Arkansas home, which is known as the Mountain Biking Capital of the World, and we even have some fantastic fishing too. So, if you happen to be in the Ozarks look us up as there are not many things better than hittin’ the trails or fishing with your homebrew buddies and then kicking back with one of our homebrews!

3rd Place: Upstate NY Homebrewers Association, Rochester, NY
Charity: Wounded Warrior Project

Upstate New York Homebrewers Association is one of the oldest homebrew clubs in the country ( we think 3rd or 4th oldest) and a big part of the Upstate New York beer scene. Founded in Rochester, NY 1979 in it has recently risen in popularity and grown to over 100 active paying members. They hold Monthly meetings the second Tuesday of every month at Sager Stoneyard Pub on Sager Street in Rochester’s University Ave neighborhood. Meetings entail announcements, educational talks on a variety of subjects like Yeast propagation, mashing techniques, Oyxgen ingress and more. Club members can take advantage of our online grain store where grain and supplies can be ordered and picked up at monthly meetings. Club members can also participate in beer hunter where if they visit an out of town brewery the club will pay for them to bring back beer to share with the rest of the club members. They also hold a monthly prize raffle for members and run a brewer of the month mini competition at every meeting. Brewers who submit entries are judged in a side by side blind tasting. Winners receive prize money and accrue points towards an end of the year “Brewer of the Year” award. Big events for the club include professional brewery collaborations, team brew-off competitions, Octoberfest and their main yearly BJCP sanctioned competition. This years the competition will be held at Genesee brewing (who is always an amazing host) September 21 & 22. This will be the 46th year of the competition and many prizes and ribbons will be awarded at our Octoberfest event at Ellison Park On October 5th. This past year UNYHA started a Hall of Fame and inducted 4 members to it’s inaugural class- Jack Mansur ( who we estimate has tried around 15,000 unique beers) Adam Odegard ( who has won brewer of the year more times than we can count), Steve Hodos ( our longest running member, time president, BJCP pioneer and ran AHA comp regionals) and Paul Guarrancini ( a 30 year plus member turned pro, beer educator & advice giver). We will ask for submissions every two years for additional hall of fame submissions.
