Hi -
I harvested my Marquette the other day, slowly starting to get more fruit here. I picked a little on the early side after dealing with wasps and rot last year...
pH 3.00
TA 13.5 g/L
SG 1.096
Anyhow, I have my fruit split up into three different primaries, and I went to make an acid reduction on one of the buckets. Using Potassium Bicarbonate, and trying to just knock it down about 2 g/L (and let MLF & cold stabilization take me the rest of the way - that's the idea anyway). As I understand, I should get a 1:1 reduction with the addition on KHCO3, so with 17L of must, I added 34 grams of KHCO3.
After all the foaming was over, I freeked out a little bit when I checked acid and found pH=3.9 and TA is at 8 g/L.
My hypothesis is that there is so much juice still hiding inside the berries, that the reaction took place just in the "loose" juice and that's why I'm seeing such large acid reduction.
Can anyone comment? Am I on the right track here???
Also, I have another 35 L that I haven't treated yet, so I can blend it back too if needed...
