I just started drinking a Pumpkin ale that I made a while back. My instructions were to add the spice at the end of the boil. It smelled great and while the wife was standing there getting ready to help me with the cooling, she said she would even be willing to drink some. Well, even though it isn't a bad beer, it doesn't taste anything like it had smelled. I had read about people making a tea out of the spices and adding it to the bottling bucket. I think that is what I will end up trying with the next batch that I make.
