Add more (fresh) grape juice halfway into primary fermentation

[PJ805]

I am making white wine from fresh grapes (1 gallon) and am two and a half days into primary fermentation. I have some space in the fermenter and about a cup of extra juice. Can I add the extra juice at this point to be fermented as well?

Sure! If it is just juice, no problem.

Has the extra juice been in the fridge or something like that?

It was in the fridge, I removed it, added a few grains of potassium metabisulfite powder (less than 1/32 tsp) and am letting it sit for 24 hours before I'll add.

Sounds like a good plan to me.
