Pedrillo:
It's a complicated recipee for the Dog 120, which is from an old issue of Zymurgy. The short of it: first pitch with a High Gravity Ale Yeast, followed in a few days by a second pitch of Champagne or Eau de Vie (sp?) yeast, followed by ten days of "feeding" with highly fermentable sugar, like dextrose, and very high IBU hops. Beer reminded me a bit of Sherry, tho it was surprisingly light in body, and had a bit of whiskey burn. Not the first thing I'd try, but if you're brewing regularly, a memorable challenge. John
