I brewed Midwest's Pumpkin Ale last month. In addition to the spice pack, I added a tea of water, 2t of pumpkin pie spice and 1T of vanilla. It has been in the bottle for about 2 weeks. I cracked one yesterday to try it out and am noticing little to no pumpkin spice flavor. Will this become more prevalent with age or do I just need to add more spice next year?
