This is something that I'm curious about. Last fall, I helped a friend to make some "Cabernet" by using an easy method: buying ready grape juice in pails and just transferring it to a demijohn, adding yeast and letting it ferment to completion. Personally I always make wine from grapes, but with all the mess and know-how involved, it's not something that would have been easy for my friend to start without perhaps seeing someone do it first. Time was an issue, so we went the juice-in-a-pail route.
The juice looked normal and all, but when it fermented out, the taste was very thin and un-Cabernet like; it tasted like white juice to which perhaps some red grapeskins were added for colour, but no flavour or tannin was present. Anyway, the strangest part is this: We see that fermentation has stopped, we repeatedly sample the wine over a few weeks - yet it still tastes sweet. What the heck? I finally do a test: I run some of the wine along the rim of the wine glass and see if, when it evaporates, it will leave a sticky residue - this would confirm the presence of unfermented sugar. Lo and behold - no residue at all. There must be some kind of sweetener in the juice. Just recently I was also served a glass of red wine made at one of those wine kit places where you can order 'x' number of bottles of "personalized" wine - and it tasted just like this stuff we made. It all started to make sense.
With me being a believer in working from grapes or fresh-pressed must only, I am even more cynical now. It seems to me that these ready juices are sweetened with some sort of non-sugar compound to give a sweet taste that will please the uninitiated wine drinker and hopefully have them order more of the stuff. I can't abide that kind of trickery and certainly will be convincing my friend to use grapes from now on!
Any thoughts on the topic? Any similar observations?
