With WY3864 coming back for this year's fall private collection, I decided to brew a cinnamon & ginger spiced beer in the dubbel/BDS ballpark. I've brewed with cinnamon plenty of times, but I've never used ginger in beer. I'm looking for something in the spice cake/christmas cookie realm - sweet spice without a load of heat. Does anyone have any suggestions based on what has worked for them? I'm thinking of using fresh ginger root before racking to a keg, but I'm not sure how much to use (for a 3-gallon batch) and how to best prepare it.
