Ok guys a little help for our cheP wine kit maker..
I haven't done one of the Fontana white kits. But, I did two whites, a Chardonnay and a Pinot Griso that I reduced down to 5 gallons...not sure that was the best move. They are kinda "thick"...not light whites...but add about 20% water and they are pretty good. That said, I don't think I would reduce the volume too much.
Bump the SG to 1.08-1.09 with added simple syrup. Maybe a Fpac of white grapes or apricots...I used dried chopped up apricots in the primary. After primary use a citrus extract or a bit of grapefruit zest.
I guess the next tweak would be oak or no oak....cheP's choice....or split the batch and do half and half...maybe even half a cup in the primary to improve the mouth feel?
How was that Joe? What do you think BossMan?
