Ah, email/news, no matter how clear I'm trying to be, there is always
some crucial bit missing... What I forgot to add was that, based on
taste, the second (higher) measurement seems correct. I also remember
thinking, after I added the acid on the Pinot B, that it tasted quite
tart. I recall you talked in a post a while back about using the taste
as the ultimate guide, only I still don't have the right frame of
reference for guessing the final balance under all that initial
sugar...

Will do. I haven't got any fizziness while sampling, but it definitely
would be a good reference point to do a test after degassing. I'll
report back.

Thx,
