2010 Sap Flow: Beware of Indoor Boiling

For the past week the maple sap flow has been on at Pure Water Hollow, and I have been boiling it down for the past 2 days, almost non-stop! We again only used 10 taps in 8 trees, just like we did two years ago. I’ve lost track of the number of gallons of sap we have harvested, but we believe it has been about 60. It has yeilded a gallon of syrup so far, with about 10 gallons of sap still on the range waiting to be finished off! If we are correct in how much sap we have had, we are hitting pretty much on that 50:1 ratio. We discovered before that our sap to syrup ratio here in Kentucky is greater than the 40:1 ratio that New England gets, but sometimes it is a bit better than 50:1. The sap flow pretty much stopped by Thursday because it stayed cold (we got more snow on Wednesday and Thursday).

The cold temps allowed me to do a trick with the sap that I have read that the Indians used to do. I was able to remove a good deal of the water content by taking the ice out of the buckets instead of just boiling it all! The unfrozen part would have a greater concentration of sugar. This helped quite a bit.

I was re-reading my maple syrup posts from the 08 season, which was the first time we attempted maple syrup. After boiling down 50 or so gallons this time around, I feel I should clear up what appeared to be a bit of misinformation. I found this statement from an old post:

"I had read in many places not to boil the sap in doors. At least one source said that all the steam would coat everything in the house with a sticky residue. After letting many gallons of sap boil on our kitchen range, I would now say the sticky residue part is a myth. After thinking about it, it doesn’t make sense that the steam would be sticky since the only thing that is boiling away in the steam is the water content. The tree sap is 98% water and only 2% sugar. About 2/3 of the water needs to be taken out. The remaining solution would be 66-67% sugar and would now be syrup. The only thing that is evaporated into the air is all that water."

Well, that year I didn’t have much trouble in the kitchen at the beginning, but after everything was said and done, Erica and Lisa did complain a bit about a sticky residue that was all over the cabinets and appliances that they had to clean up!

This year I have been doing all the boiling up at the extra house on our property that we use as a school house and storage building. Our kitchen at the house has high, 9 foot ceilings, but this kitchen has a low, 7 foot ceiling. For some reason, the condensation from the steam has been incredible this year! I was using 2 giant 21 quart canning pots, one large stock pot, and two smaller pans on all four burners on the range as well as a hot plate on the counter.

That many gallons of sap boiling all at the same time produced some amazing atmospheric changes in the room! I have had to wear a cap because of the multitude of dripping, yellowish sap droplets from the ceiling! It has been like being in the woods after a great cloud burst with water dripping sporadically all over the place from all the leaves. The walls and cabinets have been covered and discolored by the moisture as well! There are streaks of yellow running down the walls from the moisture. It has really been a mess, and when things dry, everything is sticky and icky. My shooes make a suction/sticky sound when walking across the floor! I would definitely warn folks now to never boil this much sap down in their home!

After the pots got to a roaring boil and before I opened the windows and door, a dense cloud of moisture hung in the top 4 feet of the room! It looked just like I would imagine being in a house fire would look like. The bottom three feet along the floor was clear, but above you could not hardly see your hand in front of your face! One reason for this, I guess, was that we don’t usually heat this building much above freezing, so the air was cool. With the windows and doors open, it stayed pretty cold in there, and I felt like I was in an old fashioned sugar shack that I’ve seen pictures of. The outside of the school house looked pretty cool, too, when I went out to check on the chickens once. When the wind blew the right way, great billows of steam could be seen coming out of the side window! But even with the windows and door open, it did not help the residue droplets that formed everywhere.

I still think what I wrote a couple of years ago sounds correct, in that most of what is evaporated is just H2O, and shouldn’t cause a problem. But I guess I now proved that somehow water content from maple tree sap is indeed tainted with stickiness and can in fact cause all sorts of problems!

It really hasn’t been a great problem for us, since we do not live in this building, but we will have quite a mess to clean up when everything is finished! Someday, I still hope to have a real sugar shack and use wood-burning stoves to boil the sap!

Next week, the sap may start flowing again, and we may get to produce more sugar. If we do, I suppose I will just open the windows and keep my hat on in our sugar shack/ school house/ storage building!

This makes sense because if you fry meat on the stove the same thing happens. You get sticky grease everywhere.

Sounds like fun… Do you save all your syrup or sell it?

A comment from Debbie asked about selling the syrup.

We have not tried selling any syrup, but we did give several jars as gifts, with great reviews. I probably could find some folks who would buy all that we make, but since we are doing such a small amount I don't really want to do that. We have enough trees that we could probably run 3 to 4 times as many taps as we are now, but that would also be 3 to 4 times more work! Maybe we will work up to doing more in future years, but for now, this is all I can handle!

We are planning on changing most of this year's syrup into powdered sugar. The syrup we made in 08 has lasted us until now (we still have some jars). We will likely make better use of the product as sugar. I think natural maple sugar should be healthier for us compared to commercial sugar!

Hi, we live in TN, and we just ordered equipment to tap our maple trees. Do you think it will be to late to get any syrup this year? We have been wanting to try this for a long time. We finally decided to go for it. Do you tap just sugar maples or all maples? Hope the rest of the season goes well for you.

Lyn,

I really don't know how the maple sap will be in TN. Many people around here thought we were too far south in KY for maple syrup making, but they were wrong! You will just have to give it a try.

The sap from trees in our area has less sugar content than those in New England, but I believe the syrup that results is as good and sweet as theirs is. It just takes me boiling a bit more sap than they do up north. A friend of mine vacations up in Maine frequently, and she said our syrup was as good as anything she ever gets in New England! I think the further south you go, the less sugar content you will have.

As far as timing, I would guess it may be getting too late for you this year. But if it stays cold long enough, you may still have a chance. Ours flow when we have a string of days in the 40s and nights in the 20s. I think sunshine helps a lot, too. I've read that you will get bitter sap after the trees start budding out, which should begin pretty soon. I think I will have another week or so of sugaring weather here in KY, but as we get on into the middle of March I'm counting on more spring-like weather!

We try to only tap the sugar maples on our property. The books say that all maple varieties can be tapped, but they have different sugar levels. Some day I will experiment with the other maples and see what the difference is. I think they should make good syrup, but we may need more sap to get the same results? When the leaves are on is the only way we can differentiate the sugar maple from the other maples. Two years ago we marked the trees with paint so we could find them in the winter with no leaves.

Good luck with your sugaring endeavor! I'll try to check out your blog to see if you write anything about it. If it doesn't work this year, start being on the watch next year begining in January. I made some good syrup this year in January, but it was not a very heavy sap flow.

God bless,

-Eric

Hi Eric,

Thank you so much for visiting my blog and leaving a comment.

I am sorry to hear about all the sticky! It is still worth it though in my opinion.

It really cold here again, so the sap isn't really running right now. I can not wait until the sap flows! Sap collecting and syrup making is so much fun!

I hope you and your family are enjoying the sap season.

Just thought I would drop by, read your post, and wish your sap season well.

What a great post…I remember way back when my grandparents made maple syrup…for some reason I remember them doing all their boiling outside in a big pot under an open fire…this was a wonderful time for us kids to watch that..and taste the finished product LOL.

Yes it can be a sticky mess We didn't get trees tapped before the first run this year Will try for a small fall run. Hope you get lots of syrup.

Blessings,
