Simple Grape juice Wine Experiment

Post by Geezah » Fri Aug 26, 2011 6:52 pm

My mate sent me a txt while he was in his local Costco warehouse last week saying there was 'grape juice concentrate' 6 litres for £9 ... you want some?
So, of course I said yes and ended up this week with 2 x bottles of 2.84l red graps concentrate.

So I put 2 litres of this juice in to the dj along with 500g of sugar and topped it up with water.
OG 1070

I had to taste this stuff out of curiosity and it tastes like a black grape slush puppy, so I really hope it retains some of that flavour.

I didn't boil it or anything, just added a tsp of citric acid, 1/2 tsp of tannin, a tsp of yeast nuterient and a tsp of youngs wine yeast.

Within 1/2 hr those yeasties were a breeding..

i'll keep you updated with the progress.

2 points to mention.....

Youngs wine yeast (or Ritchies for that matter), is rather mediocre - it's just "too general purpose"....

And, you'd find that grape mixes/blends like that, are designed to be palatable for drinking. At a start gravity of 1.070, it's likely that it will ferment dry. Plus as you mention keeping some of the original "black grape slush puppy" taste, then it's likely that you'll have to back sweeten it - probably best if done with some of the original juice/concentrate. Myself ? Well I'd just ferment it dry, stabilise it, then take a taste and use a little of the concentrate (which will probably be sweeter and less likely to reduce the consistency/mouth feel) to sweeten it back up.

The finished ferment will probably be quite "thin" in texture, but still display some "wine like" qualities - whereas something with the slush puppy flavour, is more "cordial-like".

I have made plenty of wines from fruit juices and off fruit itself to understand the ins and out of it all ;)
I nearly always ferment to dry, stabilise and back sweeten to the wifes desired taste, and also add gelatine on occasions to give it a little more body.
This is just an experiment to see what sort of flavour will be retained from the juice on its own, and if 2 litres was a good quantity to start with. I would generally use something like a Lalvin 71-B for a red wine of this strength, but I only had my 'turbo cider - general wine' yeast available as I used the last of my lalvin on my plums.

Fair enough. I personally don't like gelatine for adding body, I use either grape juice/concentrate, or glycerine - though you have to watch it as it can give extra (unwanted) sweetness or a hint of a metallic taste.

Ah, again, I don't use 71B for reds. RC-212 yes, but it's a pain as it can be a complete nutrient hog. I use K1V-1116 on both reds, whites and meads as it's excellent as a general purpose yeast, and is excellent with meads.....

I don't even use the ones from Ritchies that are supposed to be for specific types. I've found, for reasons unknown, that they tend to produce tastes/flavours that border on the bland..... So mostly Lalvin stuff, with occasional redstar......

p.s. but yes, I've found that juice wines are fine for "quick turnover" quaffing type wines, but apart from that, it seems that supermarket juice isn't quite as good as they'd have you believe for anything other than drinking.....
