It never ceases to amaze me, with Pinot grigio how 'black-grape' variety-like they look. Of course, anyone who appreciates a good Pinot noir based Champagne will not need York Notes to understand that the majority of grape varieties have white juice.
It is still too early to test for sugar, TA, and pH, but sensory evaluation (eating as I go), says that the grapes are still quite far from maturity.
