Hi, I’ve searched and have been unsuccessful finding a calculation like I’m looking for. I consistently reach my pre-boil gravity readings but my original gravity has been a little low. I’m assuming this means my boil off rate is being input incorrectly into BeerSmith. Is there a formula that takes preboil gravity, original gravity and time into consideration to arrive at a boil off rate? Such a thing must exist, I feel like I’m guessing too much and eyeballing when doing test boils with water and believe it would be much more accurate to take known data sets I have recorded and input it into a formula. Any ideas?
Thanks!
Thanks!
