I have a 7.5 gal pot, which is just not quite enough space to make enough beer to fill up my 19L secondary carboy. I want more beer. To achieve that without buying a new pot, please tell me if I'm thinking about this correctly:
Say a given recipe gives me, post-boil, 5 gal at 1.050. I like the beer, but I want it to be 6 gal, or 20% more volume. To achieve that, in the next batch I could adjust the grain bill to increase the OG by 20%, which is 1.060, but still use the same amount of strike and sparge water as the first batch. At the end of the boil I will have 5 gal, but the OG will be 1.060. I then dilute the batch with an additional gal of water. I will now have the same beer as the first batch with an OG of 1.050, but 6 gal instead of 5.
Thanks, Mark
