Greetings everyone. New guy on the block here. I started a small batch BIAB gallon brew this morning. During the sparging, I may have added too much water. I adjusted the amount for the boil to about 1.5 gallons. In theory, I should have 1 gal when it’s finished. If I don’t however, and need to add to make the amount up to the gallon, can I use the leftover/out wort or just use clean water to make the correct amount for fermentation?
Thank you all for your time and advice!!
