20 gallons from 2 trees.
How much actual syrup will that produce?
Never done it before.
That’s 20 gal from two trees we tapped last Friday. They usually put out twice that during the season of a week or two.
For some reason my maples aren’t sugar maples (they're some huge yard type silver maple looking hybrid), but they put out crazy high sugar content of 2.5-3.4 percent sugar (called Brix).
Gallons of sap need to make a gallon of syrup follows the rule of 86.
86 / your trees' Brix = gallons of syrup.
I haven't measured the sap's Brix this year but if it's average (say 3%) then 86 / 3 Brix = 28 gal of sap per gal of syrup.
I'm going to boil that pot of reduced sap I posted a picture of tonight on the stove (with a good vent) to get to perfect syrup sugar density (66.9 Brix) using a sugar hydrometer. I'll report later how many quarts we put up for this first batch. That sap is probably 90% of the way there - so it won't take a lot of boiling to get there.
Lots of people are surrounded by boxelder which makes good syrup too (it's a maple after all). It's not always real high in sugar though.
If you decide to give it a go don't try to boil a lot of sap using propane - it'll put you in the poor house! We used a hot plate the first year just for kicks (boiled maybe 15 gallons of sap) and liked it. So we built a POS wood-fired evaporator out of a barrel and some hotel steamer pans and we burn cull firewood.
It's sorta fun to do something productive during "mud season". Freezing nights and highs in the 40/50s is what makes sap run. If it doesn't freeze overnight then the sap doesn't flow much, if at all the following day. It's the freeze/thaw cycle that does it - somehow.
Sluggo had success a couple years ago. But he's not hooked. He's got the Missouri River for something to do in March. Grrr.
