Fermenting temperature

[JawnnyO]

I finally have everything and set. The kettle and SSVR work quite well with boiling water. When I opened my ingredient box. everything was stuck to the bottom. Something punctured one of the containers of LME. It seems to be down about half. The steeping grains are pre-measured and mixed ready to be dropped in the kettle. I have been on BrewMate and tried to figure out how to balance with maple syrup, (which I have a lot of) but it is a little beyond me. Any suggestions? Thanks.

That sucks!

how to balance with maple syrup

Do you know the gravity (sugar content) of the maple syrup? Otherwise measure it. Calculate how much syrup you need to get to your intended gravity and replace that amount of brewing water with the syrup. If you want to retain the subtle maple syrup flavors and aroma, boil with the reduced amount of water, and add the maple syrup to your fermenter.

Okay, thanks. I made the maple syrup this spring and it is a little sweeter than it is supposed to be 68 brix. I added a 1/2 cup in the boil and my OG was 140 instead of 148. It is still cooling so I could add more syrup but I don't know how much. Will yeast it tonight.
I will definitely get a wort chiller before next try. It is taking forever to chill. The pot is too big for my sink with the spout and electrical attachment. No bathtub or kiddie pool.

Do you mean 1.040 instead of 1.048?
If so, and you want to increase it to 1.048 with syrup, you need 8 more points of gravity.
Your syrup is 68 brix, which is about 1.340 SG.
So, 40 x v1 + 340 x v2 = 48 (v1 + v2) = 48v1 + 48v2 (where v1 is volume of wort, v2 is volume of syrup)
292v2 = 8v1
v2 = v1/36.5
So, you need to divide your wort volume by 36.5 to work out how much syrup you need.
If you have a 5 gallon batch, you need to add 520mL, or roughly 2 cups, of syrup to get the gravity to 1.048.

Holy Toledo! I have so much to learn.
I was trying for a 5 gallon (19 litre) batch - starting with 24.5 litres for the grains in a bag. Because my pot tap got plugged (with hops I think) I left 4 litres. so do I add 520 ml syrup and 3480 ml water to get to 19 litres?

No. I think you're saying you have 15L of 1.040 wort?

If that's correct, then add 410mL of syrup to get 15.4L of 1.048 wort.

Thanks for all this help. It has started getting a foam on the top, so I am hoping the rest goes well.

Bottled it today, 1.011, FG pretty good taste, primed with maple syrup. Thanks everybody for your help and advice.
