I had this beer, a collaboration between Terminal Gravity and Double Mountain a couple months back. It was awesome, and almost maybe I think it's better than Ninkasi Total Domination. Here's what they had to say about ingredients:
"GRAVITY MOUNTAIN combines the breweries two house yeasts, their unique base malts, and some of their signature hops to make a strong, blond-colored IPA thats aggressively hoppy and satisfying. Its a true marriage of two brewery identities. Here are the specs:
Gravity Mountain Collaboration IPA
7.2% alc by vol, 16.5 Plato, 70 BU
Brewed with Gambrinus Pilsner (Copeland variety), Marris Otter Pale, Biscuit and Munich malts
Styrian Goldings, Chinook and Brewers Gold hops; dry-hopped with Styrians and Brewers Gold"
Anyone have any guesses as to proportions, and what their house yeasts may be like? The combo of Pilsner malt and Marris Otter as the base malts seems kind of interesting...
