Weather effect on this years sap production(Southern IN)

I’m holding off a bit hoping for a cold spell; but may end up regretting it. I’m heading out this weekend to inventory and start replacing drops.

Last year I came across some examples of using Growing Degree Days to estimate the end of syrup season. (Not helpful for estimating the beginning). I'm no scientist, so what you see is what you get, but as far as when you can expect trees to bud there is some information that may be helpful here: https://primalwoods.com/revisiting-t...g-degree-days/ and in the links he includes in the blog.

Good Luck

Finished replacing taps today in the rain. Added a few, up to 155. May add another run, we’ll see.

We've got 80 on 3/16" and another 20 on buckets. Ro'ed approx 300 gallons this weekend, boiled approx 80 gallons of concentrate.l Great way to try out our homemade RO. looking chilly for the next few days.

RO’ed another 130 gallons of sap Thursday night. Headed back to boil shortly.

Looks like next Saturday I'll start setting taps. Might a few good days if the sun comes out.

Tapped 109 today, about 2/3 of my current total; but I'm hoping to add a few. It was barely moving in a few trees, but not much.

Tapped another 81 today putting me at 190. I think I’ll put in another run next weekend to get to 200. Problem now is it’s too warm. I’m worried sap will be bad by next weekend. It was running pretty good today (2 of the runs had 29” of vacuum). All of mine are on 3/16, but I’m experimenting with a 5/16” trunk line to bring 5 barrels together at one spot. I don’t have all the pieces to tie the barrels together yet, so right now the main part of the trunk is laid, but only to one barrel and the rest still individual barrels.

Finished off the sweet from our previous boils today, made almost 7 gallons of syrup. Lines and buckets running well, currently RO’ ing another 100 gallons of sap for tomorrow’s boil.

Collected another 200 gallons since Monday night, all RO'ed and boiled down to almost 5 gallons of near syrup. Will add that to the near syrup from Monday's boil, and finish off this weekend. Closing in on 800 gallons of sap thus far for the season. Still dripping tonight, but slow. Need some colder weather to recharge the trees.
