What kind of boil off is everybody getting doing a ten gallon batch. I think I have pretty much everything down for my first AG batch other than how much water to start with.

I do 5 gallon batches and lose 1 gallon in a 60 minute boil. Generally you will lose 15% an hour.

I posted the same question awhile back.

I figured I am getting about a 24% boil off.

I lose about a gallon per hour, rolling boil, using a keggle and a ~210k BTU banjo burner.

If I recall my high school chemistry stuff, the boil off rate would be set by the heat apllied and the surface area. So, same burner, same pot, same rate. If 1 gal/hr for a 5 g batch, 1gal/hr for 10 gallons.

Of course, if you need to sparge more to get the sugars, you'll need to boil more.
So far, I've had more experience thinking than I've had don't think they are mutually exclusive, do you?

72 batches so far,
48 wine, mostly Loquat, peach, plum, prickly pear
23 beers and ciders
1 sauerkraut
1 Tequila, from a prickly pear wine experiment that didn't work. I call it "Prickly Heat"
