1. For the boil, yes. As a fermentation vessel? I'd recommend against it. Aluminum is somewhat reactive, especially to acids that may be produced by yeast. 2. Doesn't matter. If you use whole hops, they do absorb more liquid than pellets do, so you'll want to add excess water to the beginning of the boil to compensate not just for evaporation, but also for hops rehydration too. 3. Your shop carries the Fermentis products, so I'd recommend the S-04 or the US-56. ← Thanks I have done my shop and everything should be arriving shortly. Harrah cant wait till the next installment. Thanks again for your effort Rom
