Notes

Event Horizon Peanut Butter Cup Stout: A Galactic Indulgence

Journey beyond the ordinary with the Event Horizon Peanut Butter Cup Stout, a brew so rich and deep, it feels like peering into a delicious, dark abyss. This audacious American Stout pours an impenetrable black, crowned with a luxurious, tan head that hints at the treasures within.

From the first sip, your palate is enveloped in a universe of flavor. A robust backbone of Maris Otter and specialty malts—including roasted barley, chocolate malt, and de-husked Caraf—lays down layers of dark roasted coffee, bittersweet chocolate, and a hint of espresso. The substantial addition of flaked oats and unfermentable lactose contributes a velvety smooth body and a luscious, creamy mouthfeel that defies gravity.

But the true spectacle lies in the celestial collision of flavors: a generous swirl of PB2 (peanut butter powder) during the boil delivers an unmistakable roasted peanut essence, while a precisely crafted cocoa nib tincture added in secondary amplifies the dark chocolate notes. The result is a harmonious, decadent fusion, perfectly mirroring the experience of biting into your favorite peanut butter cup.

At a commanding 6.31% ABV, the Event Horizon Peanut Butter Cup Stout is a complex, indulgent, and immensely satisfying beer. It's a dark star of a brew, drawing you in with its gravitational pull of rich, dessert-like flavors. Prepare for an astronomical delight.
