Tomorrow I am going to try a full boil and double batch for the first time. I recently got a 15g pot so I thought I would give it a try. We are doing a kit made for 5g, so we bought 2 of them. Is it as simple as following the instructions but just doubling, ie put both grain bags in while steeping, same hop schedule but double etc? We are going to do late extract additions to keep the color lighter. Also thinking we will start with 12.5g of boil water. Is there anything I am over simplifying or missing in this process?
