When Goose Island Brewing Co.’s Autumn Variety Pack goes on sale in August, it will include a new beer.

Experimental Ale is a 5.7 percent ABV “extra special bitter” that incorporates 2-row, wheat, c-60 and c-120 malts as well as cascade and columbus hops that are grown at Elk Mountain Farm in Idaho. The new beer features a recipe based off of the Chicago, Ill.-based brewery’s Harvest Ale (5.7 percent ABV).
