Chesapeake Bay Porter -- A Taste of the Bay in a Pint

Nothing beats a smooth, roasty pint on a crisp Chesapeake evening. Inspired by Maryland's working waterfronts and winter bonfires, Chesapeake Bay Porter captures the essence of the region in a glass — dark, chocolatey, and just sweet enough to keep you coming back for another sip.

This approachable porter sits at 5.9% ABV, delivering depth without heaviness. Its core rests on a sturdy blend of American malts and a touch of local pride.

The Grain Bill

Built around Behmalt Pilsner Malt 2-Row, this beer starts with a light, crisp base. The Pilsner malt contributes a clean fermentable canvas so the roasted and caramelized malts can shine without excess weight.

• Briess Caramel 6-Row (20.9%) adds sweetness and body, supporting the roastiness with toffee undertones.

• Briess Chocolate malt (13.9%) drives the beer's heart — delivering coffee, cocoa, and a deep chestnut color, reaching nearly 40 SRM.

• Flaked Barley (7%) lifts the body and improves head retention, giving this beer its satisfying, creamy mouthfeel.

• Lactose (6 oz) rounds it all out with subtle sweetness, softening the roast and making each sip silky and smooth.

The Hops

Classic Willamette hops bring mild, earthy spice and a gentle bitterness (26 IBU total), while a late addition of Crystal hops adds a faint floral accent at the finish. The balance — a BU:GU ratio of 0.44 — favors malt, reinforcing this beer's easy-drinking porter identity.

The Fermentation

Using the clean, reliable US-05 yeast, fermentation at 68°F yields a restrained ester profile and allows the malt character to remain dominant. A final gravity of 1.013 leaves just enough body to carry the roasted flavors without drifting into overly sweet territory.

The Result

Pouring dark brown with ruby highlights, Chesapeake Bay Porter greets you with aromas of cocoa, toast, and a touch of caramel. The sip is smooth — roasted malt up front, sweet cream mid-palate, and a gentle earthy bitterness to close. Carbonation at 2.3 volumes of CO₂ brings just the right lift to its velvety texture.

It's a beer designed for the dock, the hearth, or the back deck at sunset — wherever you like to savor the can't-rush calm of the Bay.

Brewmaster's Notes

• Potential improvement: Add a small charge of black patent or roasted barley (up to 2%) for a sharper roast edge if you prefer a drier finish.

• For experimentation: Try cold conditioning for two weeks at 36–38°F — it will polish the flavor and clarify the beer beautifully.

• Food pairing: Oysters, BBQ brisket, smoked bluefish, or a square of dark chocolate.
