I boiled 71 gallons of sap this weekend in just over 15 hours. What a blast! My kids thought I was king of the world when we finished our first gallon. It is a little on the dark side but the taste is wonderful. I have not bottled it yet but it looks like I probably have just over a gallon. I really enjoyed playing with my homemade evaporator, learning all of its tricks to get the best boil. Thanks to everyone on this forum who offered advice. I can't wait for next weekend so we can do it again. So much to learn!
