This is the second year for the Brewtus Mashimus cup between Brewcommune and OC Mashups.  Last year, 2018, OC Mashups took home the cup.  So this year Brewcommune gets to choose the rules for the contest, along with this year's participating brewery Gunwhale Brewery.

This year's contest will have a cap on SG of 1.040.  For the best of show portion of the contest, Gunwhale Brewery will be choosing a beer to brew on their new system in Orange and they want a beer that fits with their ethos:

“Our beers strike a balance between the raw, wild spirit of farmhouse brewing, and the pioneering hop forward styles of California. We have an obsession with yeast driven Saisons, hoppy IPAs, and other rustic, wild and sour beers. This gives our beers uncommon qualities that are both surprisingly delicate and nuanced, yet refined and robust in their simplicity. From bright, billowy summer ales to rustic, fortifying stormers that stand up to the rougher seas, Gunwhale makes beers that reflect the culinary and cultural heritage of the West Coast. “

See the list of accepted styles.  If you have any question about styles, please contact the contest coordinator.

This competition is AHA sanctioned and open to amateur homebrewers age 21 or older.

Only members of OC Mashups and BrewCommune are eligible to enter.

Each member can enter up to two entries.

All entries will be picked up from drop-off locations the day of the drop-off deadline.

All entries must be handcrafted products, containing ingredients available to the general public, and made using private equipment by hobbyist brewers (i.e., no use of commercial facilities or Brew on Premises operations, supplies, etc.).

The competition organizers are not responsible for mis-categorized entries, mailed entries that are not received by the entry deadline, or entries that arrived damaged.

The competition organizers reserve the right to combine styles for judging and to restructure awards as needed depending upon the quantity and quality of entries.

Qualified judging of all entries is the primary goal of our event. Judges will evaluate and score each entry. The average of the scores will rank each entry in its category. Each flight will have at least one BJCP judge.

Brewers are not limited to one entry in each category but may only enter each subcategory once.

The competition committee reserves the right to combine overall style categories based on number of entries. All possible effort will be made to combine similar styles. All brews in combined categories will be judged according to the style they were originally entered in.

The Best of Show judging will be determined by a Best of Show panel based on a second judging of the top winners.

Bottles will not be returned to entrants.
