grape wine

Sep 30, 2003 5 Replies

I'm in the process of making some wine from Welch's 100% grape concentrate. I've added enough sugar to bring the SG to 1.095 but now I'm unsure about how much (if any) acid blend and/or pectic enzyme should be added per gallon. If anyone has a recipe or advice it would greatly be appreciated!


hi ron, check:

this is for 1 gallon, so adjust if necessary. hth jim book

concentrate.

concentrate.

It's always best to test the acid with a test kit (they only cost about $5) to determine how much (if any) to add, or if reduction is necessary. The acid can vary radically between one batch of juice and another. I've added anywhere from 1/4 tsp to 1 tsp per gallon.

I don't use pectic enzyme, and I've never found it necessary with grape juice (or apples for that matter). Are you using bottled juice (made from concentrate) or frozen concentrate?

If bottled juice, do NOT add sulfite prior to fermentation. There is already

120ppm in it. The frozen may or may not be sulfited. If it is the label will indicate that sulfites have been added (but not the amount).

Does anyone know where to obtain one of these acid test kits in the UK ? I've searched high and low.

Any homebrew shop should have them for £4-5. Check your telephone directory listings under "Winemaking" or "Homebrew Shoppes". What part of the UK are you in?

Here are a few internet links to shoppes offering such kits:

Also, Boots (the Chemist) used to carry them. Perhaps they still do.

Thanks !!!! It appears that the Home-Brew-Shop is just up the road. Our local big one in Southampton did not have any.

In answer to your question, I recently moved to Eastleigh in Hampshire.

Thanks again, and btw, I enjoy your posts. Very informative.
