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).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.

(Which I think is 1 unit brix = 1 ml sugar per 100 ml liquid)
I calculate then that the F-Pack is 77ml + 38.5 ml = 115.5 ml sugar which is very close to 1/2 cup sugar (118 ml).
That is not a lot for 6 gal of wine. ie 1/12 cup per gallon
A low -medium sweet which I often like is 1/3 cup per gallon = 2 cups sugar for six gallons, 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.
..@Chinook Brix is actually a weight percent sucrose, so you have to be careful with calculations when converting to volume measurements. It can get complicated, so using Fermcalc is probably the easiest way to estimate the numbers; @Johnd is correct if the f-pac was around a quart or liter, so running the calculation again using the example above of 150ml at 77 brix f-pac, Fermcalc indicates the f-pac would contain 161 grams sugar, and using standard sugar weight to volume conversion indicates that 161 grams of dry sugar would be near 3/4 cup dry volume measurement. I don't really know what else might be in the fpac, as things like fructose, glycerine, and acid would likely alter the final taste.
Good all round site. I was using a simpler one for SG to ABV. This site is better.
