GTA Brews is excited to announce our eight annual nation-wide homebrew competition for beer, mead, and cider: Brew Slam 2025 (#BrewSlam)!
#BrewSlam is Canada’s largest homebrew competition, with hundreds of entrants from Canada and the USA. We can’t wait to build on 2024’s massive success. That competition saw 552 entries from 140 entrants representing 8/10 provinces, judged by 60 judges over just 3 days, which made it the largest homebrew competition in Canada!
This is a BJCP sanctioned competition and is part of the Canadian Brewer of the Year (BOTY) circuit. The judging will take place at Mascot Brewery Etobicoke (37 Advance Rd) from Oct 24th to 26th. Judging will be performed by BJCP ranked judges and pro brewers using the 2021 BJCP Guidelines.
Entries for Brew Slam will be accepted at the shipping and drop off locations beginning on Sept 29th, several weeks after the system starts accepting entry registrations on Aug 22nd. The entry deadline for all entries to arrive at the shipping and drop off locations is end of business day on Saturday Oct 18th. Ship early to avoid delays.

Brew Slam has Pro-Ams, “Brewer for a Day”, and thousands of dollars in prizes up for grabs. If feedback alone isn’t enough to convince you to enter our competition, then our list of prizes should be!
We are also excited to work with some fantastic sponsors for even better prizes than what we had last time!
Visit our Rules and Submission Instructions page!
Our rules and submission instructions are fairly standard and relaxed, but please make sure to give them a quick look. This page also has the addresses for our drop off and shipping locations.
Visit our BJCP Competition Guide!
First time entering a competition? Want a quick refresher/overview about how it works? This guide also explains why no beer is ever out of style when entered correctly, every beer you can brew has a home in the BJCP Guidelines.
Visit our Volunteer page
We need as many volunteers as possible to make this competition a success. If you are reading this, and are able to be in Toronto Oct 19th, 24th, 25th, or 26th, we need your help! We need judges, stewards, and even bottle sorters.
Toronto has the largest pool of BJCP judges in Canada which allows us to keep flight sizes low and focus on the best quality judging and feedback possible.
We are planning a series of incremental rewards to thank our volunteers for their time, check out the volunteer page for more info.
