grape juice concentrate - substitution?

[TheMumbler]

I have an old recipe book for home winemaking and brewing that has a ton of wine recipes which call for white grape juice concentrate (usually half a pint). Presumably this can be replaced with grape juice since most of the recipes finish with "water to 1 gallon". I'd be grateful if somebody could tell me how much normal white grape juice I should use to replace half a pint of concentrate. Example recipe below to give some context.

orange juice, tinned

1 large tin orange juice (19oz)
0.5 pint white grape juice concentrate
2.25 lb sugar
1 nutrient tablet
G.P. yeast
0.5 tsp tannin
1 tsp glycerine
water to 1 gallon


cheers

As far as im aware the only substute for grape concentrate is rasins. Then i think it about 1lb of rasins = 1/2 pint of concentrate.
But im sure Moley or Sam will come along soon and prove me wrong.

That orange juice recipe looks remarkably like a Wurzel's, so just go with a litre of white grape juice.

Otherwise, Dave Corby is spot on, 250-500g of chopped raisins, according to recipe.

Grape Juice Concentrate from your homebrew shop contains juice of wine grapes, supermarket grape juice is mostly from dessert grapes, which don't have anything like the same qualities.

Sugar wise, supermarket grape juice has 1/4 to 1/5 of the sugar in an equal amount of concentrate but as has been pointed out the type of grape is completely different. I've never tried a pure grape juice wine, I will one day...just not in a hurry as I don't expect it to be very good.

Far better to go with the raisin option, the only pain is doing the initial fermentation in the bucket.

Thanks for the replies :thumb: . I'm really just trying to get a feel for how to modify the recipes I have to hand with no real access to grape concentrate. So sugar wise it is roughly 1l of grape juice to replace the 0.5 pint of concentrate but maybe better to go with raisins.

That orange juice recipe looks remarkably like a Wurzel's.

The book is by B.C.A. Turner...

 

So, which came first, Worzel or Terner? :whistle:

Read the first sentence of the original post, Wurzel does credit Turner.
