Coffee By Design will hold a launch party for Maine Beer Co.’s annual stout from 1 to 4 p.m. Sept. 7 at 1 Diamond St.

This year’s brew is nicknamed Bartender’s Brunch and, in a collaboration with Coffee By Design, it contains certified organic Ethiopian coffee.

Guests will receive samples of the stout and of Maine Beer Co.’s Lunch, a West Coast-style IPA, served in a commemorative tasting glass.

In’finiti will serve a sample-sized cocktail made from its spirits and Coffee By Design coffee.

Other samples include a 12-ounce cold brew coffee, a savory hand pie from Maine Pie Line, and a doughnut from Holy Donut.

A limited number of tickets are available online for $25 at bartendersbrunch.brownpapertickets.com.
