replace the amount of concentrate in ml with chopped raisin or sultanas in grams so 250ml of concentrate = 250g of chopped raisins. I have seen a one or two recipes using tinned fruit, not totally convinced but I will dig one out for you and post it here now in a minute like.
Here we go copied form CJJ Berry early edition only imperial measurments im afraid, but 16 oz is approx 453g.
TINNED PEACH OR APRICOT
Ingredients:
15 ½ oz. or 16 oz. tin peach slices
½ teaspoon tannin
1 ½ lb. sugar 1 nutrient tablet
½ lb. malt extract
Sauternes wine yeast
1 teaspoon citric acid
Water to one gallon
1 tablespoon pectic enzyme
Method:
The peaches can be bought in slices in either 15 ½ oz. or 16 oz. tins, as halves in 16 oz. tins, or labelled "white peaches" in 16 oz, tins. Wine firms also sell peach pulp.
One 15 ½ oz. or 16 oz. tin of either will make, using the quantities in the recipe, a light dry table wine, but if a fuller-bodied wine is required use two tins of peaches (roughly 2
lb.)âthey are quite cheapâand increase the sugar to 2 ¾ lb. (U.S. 2 ½ lb.), the citric acid
to 2 teaspoons, and the tannin to 1 teaspoon. Pour any syrup into your fermenting jar, then mash the fruit with a stainless steel spoon.
Boil two quarts of water and dissolve the sugar and malt extract in it, then put pulp into polythene bucket and pour the boiling syrup over it. Allow to cool to tepid (70 degs. F) before adding acid, tannin and pectic enzyme. Stir well, cover closely, and leave in a warm place.
Next day stir, pour the whole into the fermenting jar with the syrup from the can, and add yeast, nutrient, and enough cold water to bring level of must to just below the shoulder of the jar, leaving room for a "head." Fit air lock and leave in a warm place for 10 days, shaking jar daily to disperse pulp through liquid. Then strain into fresh jar, and top up to bottom of neck with syrup. Ferment out, racking and bottling as usual. For a
sweet wine use a 1 lb. 12 oz. tin of pulp and 3 ¼ lb. of sugar.
Personally, I would pour out the juice from the tins into your FV then top up to 1 gallon then take a hydrometer reading then adjust the sugar to make the percentage you want ie 1090 for around 12%. I havent seen malt extract in many wine making recipes, I would chuck in 500g of chopped raisins or sultanas to give it some body. And why not use 2 cans, for the price of them why not? Also seen as no boiling water is involved 1 crushed campden per gallon in the must should be used. Sorry if I am trying to teach grandmother to suck eggs but I have no idea of your knowledge.
Let us know how it turns out.
Edit: preservatives may be a problem, and reading jack Keller you get what you pay for in terms of the end product tasting like peach, cheap tins may result in cheap wine, taste the peaches do they taste really peachy?
