DETROIT – Breweries across Michigan and beyond banded together after a tumor was discovered on a beer delivery driver’s brain. M4 CIC, the beer wholesaler Baker works for, asked the breweries it works with to help. Detroit’s Batch Brewing Company is currently brewing a fresh batch of O.P.G. Each year, the Drafting Table Brewing Company in Wixom picks a nonprofit to support on Christmas Eve. Other breweries expected to help with beer releases over the next few months include Brew Detroit, City Built Brewing Company, Ellison Brewery and Spirits and Speciation Artisan Ales.
