Rules

LAB Open 2025 is here!

The LAB Open Competition and Festival is a BJCP-sanctioned competition where your homebrewed beers are assessed by qualified judges against current style guidelines.

Score sheets and written feedback are provided on each entry. Rosettes, certificates and prizes are awarded in each of 12 (or more) category groupings and for Best of Show places.

The beers are made available to sample and discuss with fellow competitors and friends in a festival-type setting on the afternoon of Sunday, July 6th, from 1:30 PM, providing a unique opportunity to sample hundreds of homebrews, arranged in their style groupings, with excellent examples of the styles flagged. A rare chance to compare your beers against others brewed to the same style, or to explore the wide range of styles being made today.

Beers will be assessed against the BJCP Style Guidelines 2021 available via this link. 

Eligibility: This competition is open to everyone, worldwide. Competition Organisers, staff, judges and stewards may enter the competition. Measures are in place to ensure fair, anonymous judging. Judges and stewards will not be assigned to categories that they have entered. Entries must have been made at home.
