This is going to be a deep dive, but I know we have at least 1 maple guy around here. So..

We bottle Maple to 16.0 fluid ounces (most of our other product is by weight). It's worked out that average density of maple syrup being 11.02 lb/gal comes out to 1.4lbs, or 635 grams per bottle. (we do 634g, I'm assuming to adjust for overfill issues in the past).

My issue is that FREQUENTLY this still causes over fills, maple gushing over the top of the bottles. More research has shown me that the density swings seasonally (looks like spring is slightly higher brix= higher density). This is where my research gets muddy and I can't find any good answers...

How are maple packers adjusting for density? Are you using fill levels instead of weight exclusively? My brix swing is very minimal (spec is 66-68.9°Bx hard stop). I wouldn't think that would be enough to over fill jugs and I can't find a correlation to high brix and overfill (although I have very minimal data, this is an issue processing recently alerted me to).

 

Hoping a maple gal/guy has some insight. I can't keep going out there and licking up all the spilled delicious warm maple even if I want to (guys it smells so good in the plant when we're running maple you don't even want to know).

Not a maple guy. You need either bigger bottles or go by fills in oz. 

 

Do you sell by ounce or by lb?

We label the maple for sale by 16 fluid ounces. The bottle will hold 16 fluid ounces easily so that's not the issue. They are opaque bottles and we use weight to adjust fill levels.

How do you know what weight (in gm or lb) will make 16 fl oz? Do you guys do hourly fill checks or something? Are you able to adjust scale parameters?

Daft question, why not measure your density for each run? Then your addition and weight control can be converted to volume. And you'd probably save a fortune.

 

If you have a lab or office on site you can use a pycnometer or there are various other methods.

Not daft at all, that might be what the previous director would occasionally do. The assistant shift supervisor claimed the previous director would come out and give them a target weight on occasion. I'm guessing it was when he found density shifted enough that he needed to.

Hoping to work out some type of brix/density correlation or figure out how he was measuring density and go from there. I am absolutely not a food scientist though and my research has seemed to hit a wall.

The weight was worked out previously. I did find in my research that it was accurate though. I have used a site in the past that has some density/fill conversions and it had maple listed, which matched up exactly with what we were already doing:

I don't know anything about syrup either, other than the kind Buddy the Elf drinks in the mailroom.    Is it required to do it in FL Oz?   Why not just do it by weight instead of volume and be done with the issue forever?

 

Edit:   Nevermind, just Googled and got my answer for that.....

Of course that info is available online. But not density of every batch or seasonal maple as you say they vary.

Maybe some thing below will help

looks like the easiest solution is measuring density PRIOR to bottling / batch

Yeah, that second one looks promising I'll go over it in full when I get a second.

Who'd have guessed a Canadian would have all the cool maple links.
