Belgian Style Pilsner

5.4%
Hops: Perle, Styrian Golding, Tettnang
Malt: Belgian Pilsner, Vienna, Cara Blond, Cara Ruby
Named for the glimmer of moonlight on a tranquil ocean, this beer is crisp, calm, and effervescent without sacrificing flavor or complexity. This Belgian-styled interpretation of a Pilsner begins with a nose of golden apples, Belgian candy, and a subtle hint of rainy forest. On the tongue, waves of strawberry and bubblegum marry with a menthol and clove-like mouthfeel. Subtle Noble hops finish this beer with a dryness comparable to a German-style lager, leaving the palate ready for one (or several) more.

Created with 6 different Belgian and German malts, a yeast strain from the southeastern region of Belgium, German Opal hops, and finally North American Mosaic Hops. This complex build yields a beer that we like to call “summer in glass”. The glass is filled with aromas of peaches and spices while the finish is smooth and reminiscent of biscuits. This beer is a perfect complement to any summer day or evening.

This beer is crafted with care and time. We begin with Belgian pilsner malt, rye, and white wheat. In the boil kettle we add German Opal, French Triskel, and German Tettnang hops. In fermentation we begin with a saccharomyces strain of yeast from western Belgium. We let that yeast strain do its work and when it is finished we let a strain of brettanomyces claussenii take over. What is created is an elegant beer laced with aromas of pineapple, guava, jasmine and herbs. Subtly sweet and spicy on the palate and finishing with a lingering dryness.

A balanced hop profile comprised of Cascade and Columbus create a bitterness that is clean and subtle.
