Last night I decided to try putting my flask directly on the electric burner to make my 1L starter for the 1045 pale ale i’m planning on brewing tomorrow. Prior to reaching a boil the flask started making sounds that caused me to get nervous so I poured the flask into a bot to finish my boil. Finished the starter and poured back into flask. I noticed during my “experiment” that I boiled off about half of my original volume. I’m using recycled yeast from my last batch so I poured the boiled/cooled water from the mason jar back into my starter to make up for all the boil off. I haven’t taken a gravity reading on the starter yet but I was curious what some thoughts are on topping off with the boiled/cooled water? Should I just start over?
Currently starter is on stir plate and looks normal. What gravity should I expect for a starter with 650mL of water and 1/2 cup of dme?
