Bottle Logic Brewing is raffling off the first ever 1.5 liter magnums of two of its most popular creations for charity.

The two magnums contain the Anaheim-based brewery’s Darkstar November, a 14.1 percent ABV bourbon barrel-aged Russian imperial stout brewed with rye and molasses; and Red Eye November, a variant of Darkstar November that also incorporates Brazilian Oberon and Sumatran coffee beans sourced from Mostra Coffee in in San Diego.

According to a post on Bottle Logic’s Eventbrite page, the “closing net sum” of the money raised will be donated to Riverbed Renewable Farms, a “fully-functioning sustainable urban farm which grows and gives away hundreds of pounds of fresh food each month to underserved families throughout the Anaheim area.”

Raffle tickets are $5 each and can be purchased until 11:59 p.m. on Dec. 10 with no purchase limit. There are two pools of tickets, one for each of the two magnums, and winning tickets will be drawn on Dec. 11, with winners notified by email.

Winners will then have one calendar year to pick up their bottle at Bottle Logic, and proxies are not being permitted.
