Sorry, Brendan, but it doesn't work that way. I'll admit I was guessing on the amount the volume changed, but here's proof that it does change, and significantly.

From the Handbook of Chemistry and Physics, a 30 Brix sucrose solution has a density of 1.129 kg/L, so that a liter of that solution has a mass of 1129 grams. By Wikipedia's definition, "One degree Brix is 1 gram of sucrose in 100 grams of solution and represents the strength of the solution as percentage by weight (% w/w)."  Therefore the mass of sucrose in that liter is (30/100)1129, or 338.7 grams of sucrose.

Since the mass of the water is everything that isn't the mass of the sucrose, in that solution, the water has a mass of 1129-338.7=790.3 grams of water. By definition, that water has a volume (assuming 4 C) of 790.3 ml, but the total volume of our original liter is 1,000 ml. 790.3 ml of water plus 338.7 grams of sucrose give us a whole liter of solution, way more than just the water.

Yes, it would have been way simpler to solve a problem in grams and liters, but the problem was stated in cups, gallons, and liters, so I had to convert.

I'll stick by my numbers that the problem as originally stated specified a solution almost certainly too concentrated to ferment.
