Does anyone know the brix of the typical fpac in a Winexpert kit?

Can't say that I've ever checked, but I imagine it would be a little tricky to do. My refractometer only goes up to 36 BRIX, and I imagine it's a lot higher than that, and probably to viscous to use your hydrometer, and it's probably off of that scale too. You'd probably have to use a known quantity of fpack and water to thin it out to get a reading, and then convert it back.

Based on my past experience, the fpack typically raises the SG of 6 gallons of must around SG .015. Working backwards from there on Fermcalc, using starting SG of 1.090, and final SG of 1.105 (an increase of .015), for a 6 gallon must, it would take 2.4 pounds of sugar. If (I repeat IF) the fpack is 1 quart in total liquid (ignoring skins, seeds, etc), the BRIX of that liquid would be 81, SG would be 1.421. Purely hypothetical based upon the volume.

Thanks for the responses. I bought a 0-90 Brix refractometer. The fpac that came with the WE Diablo Rojo kit is 77 Brix, 150 mL.

I have this kit. This is the first time I investigated "Brix", So from understanding the Brix measurement I calculate then that the F-Pack is 77ml + 38.5 ml - 115.5 ml = very close to 1/2 cup sugar (118 ml).
That is not a lot for 6 gal of wine. A low -medium sweet which I often like is 1/3 cup per gallon = 2 cups sugar for six gallosn about 473 ml. Stronger sweetening that I see others often like, like for dragon blood or skeeter pee can go up to 1/2, 1/3 or even one cup per gallon.
...
And knowing that it is primarily sweetener/sugar I think I will just add it to the primary to increase the SG (from Joeswine Recipe in a previous thread).
I do my own back-sweetening calculated to my taste with precise formulas.
Good information here apropos!

...I haven't tried to measure the sweetness level of say.. Niagara mist fruit wines but I think I would like to get a more scientific reading of them since I made so many of them. I just had an idea I never tried - put the Niagra Mist F-Pack totally in the primary and then backsweeten to 1/3 CPG. I haven't done that before I guess because I thoght I wold lose the fruit taste of the F-Pack ..but if back-sweetening pulls out the fruit taste then I can finally tame these fruit kits to my specifications. The main reason for my buying the Mist Kits is the flavour packs but now maybe I can make my own flavour packs just as good.
