Calculating time to reduce alcohol in wine using heating method

[QUOTE="JT Smith, post: 6867409, member: 648656"] GC refers to gas chromatography. Probably more than you are willing to spend. :[I]-[/I]) Being human we can always hope... even if it's impossible. I'm pessimistic about using a refractometer because we don't have a formula or table for the RI of a dealcoholized wine, never mind your particular wine. Somebody smarter and more experienced could probably tell you if there were reason to hope. I wonder if it might work better to measure the density with a hydrometer. You could heat a small sample of the wine in an oven until it is fully dry and weigh the residue. You'd need a pretty good scale. Alternatively you could heat some wine until it is so reduced that you can feel confident that very little ethanol remains. Then reconstitute that and measure the density. Either of those approaches will tell you how much dissolved material is in the wine, besides ethanol. Then I think you could subtract that off of hydrometer measurements of wine with ethanol. I think that might work. You could check it against the unadulterated wine to see if it really works out to 15%. I could just be dreaming. I'm not a scientist, I just play one in the kitchen sometimes. [/QUOTE]
