WHEAT WINE! WHEAT WINE! WHEAT WINE!
But seriously... wheat wine is a wonderful thing to have in the fall. Warms the bones as the summer fades..
ABV - 9-11%
IBU - your preference based on what you enjoy in barleywine - higher for american, lower for english
Hop selection - ditto on above, but I like cascade
Yeast - English Ale, Denny's (english ale will provide a good malt backbone, esp. if you use Marris Otter)
make a standard, pale ale mash and then pump up the gravity with that wheat during the boil!
Age until October (on french oak if you prefer - but not soaked in spirits, it will cover up the subtleties)
