Wine wont Ferment?

Postby lizcrump22 » Fri Oct 18, 2013 3:58 pm

I had Cabernet Sauv grapes picked at an average of 23 brix. Crushed and destemmed, allowing them to ferment in natural yeast. Nothing happened. I used two different hydrometers and specific gravity hovering just about 0, no alcohol % registered. Tried adding yeast, nothing again. Tried to add yeast yet again thinking my batch of yeast was bad. Now they are in car boys, oxygen lock on, nothing happening. what could be wrong? temperature is at about 70 desgress. any help much appreciated.!

You didn't give any kind of a timeline on when you did all of this and how long you waited in between?

if you were relying on the wild yeast in the air to start the fermentation it may take some time for you to see any signs.

Did you use Campden or sulfite? Maybe you killed most of whatever wild yeast was in there. Or maybe there just wasn't much on these grapes for whatever reason.

Is fermentation complete? Have you tasted the wine? Does it taste like fresh juice, or like 12% alcohol? I realize these are very basic questions, but they are extremely important ones if you want us to help you.

There are more transfers that take place when making wine with these kids so you want to minimize your headspace once primary fermentation is done. Capable bottles may well work with a reisling that you likely won't store/age for any extended period but I would not use capped bottles with anything to be aged. Otherwise the same things come into play with wine as with beer - sanitation, temperature control, etc.????
