Feels really close...

The heat is doing a number on the vines.  Lots of yellow/crinkled leaves when I got back into town and checked tonight.  And on top of that, my drip system has died - some problem with the valves.  I tried feeding water back in manually with a bypass hose tonight so we'll see if that works.

I took 100-berry samples of both grapes tonight for testing:


Merlot:
Brix: 23
pH: 3.24
Acid: 0.4 - 0.5 (?)

Cab Franc:
Brix: 20 3/4
pH: 3.22
Acid: 0.6 (?)

I think the Merlot are techically ready to pick.  The grapes are very soft/squishy feeling with a few out there even starting to shrivel.  When we tasted the juice after testing it, it was delicious!

As the numbers would indicate, the Cab are close behind and the juice there was quite sweet and tasty as well, with just a hint of tartness/bite.  Waiting for professional feedback on next steps, lol.
