TASTING NOTES

Atom Critical Temperature Imperial Stout

RoastedCoffeeChocolate

Atom Critical Temperature hits clean and architectural. There's dark chocolate and a whisper of coffee, but nothing overshadows the structure—the roast is dark without being acrid, the body is substantial but not syrupy. It drinks like an imperial stout that respects your ability to finish it. The 65 IBUs sit there like a backbone, preventing any flabbiness. This is a stout for thinking, not just drinking.

Sudden Death Black Knight

RoastedChocolateCoffee

Sudden Death Black Knight is a full embrace—thicker mouthfeel, deeper into molasses and cocoa, with a faint licorice note creeping in. It feels heavier than Critical Temperature despite nearly identical ABV, which tells you something about how they're built. The bittering is there but takes a backseat to the malt character. This is a stout that wants to coat your mouth and linger.
