O.K. I looked for this answer on the forum, but I couldn't find it. So here it goes...This question seems really trivial but I don't want to waste anything. I recently picked up equipment to brew 10 gallon batches. Is it as simple as doubling everything in a 5 gallon recipe? Including 2 packets of Wyeast Activator? Any insight would be most helpful, Thanks.
Yes, you can simply double everything. That means doubling the amount of yeast too. So if you're asking "do I pitch two smack packs into my starter instead of one?" the answer is no, you can almost always use one pack and build a larger starter. If you aren't making starters, 10 gallons of stardard-gravity ale requires about 4 smack packs, a lager would need 8 packs, etc. http://www.mrmalty.com/starter_faq.htm
