Just moved into my new apartment and decided to get my numbers for my new brewery.
So I filled my brewpot up with 4.5 gallons of water and let it come to a boil (actual water temp was about 208 degrees), then timed it for exactly 1 hour full boil.
I let the water cool off overnight and started measuring... came up with 3.42 gallons left over. Using the equation from BYO.com:
Evaporation percent = 100 - (post-boil volume x 100 ÷ pre-boil volume)
I ended up with a Evaporation Loss of 24%. Thats a damn lot of loss. It says in the article homebrewers should expect around 6% to 8% loss.
So should boil at a lower temp???
Have any of you measured your Evaporation Loss? and if so, what is it?
Any sugestions on how to lower mine?
