Totally new here! This the first year my La Crescent grapes can be harvested. Right now the brix is between 22 and 25 but they still look pretty green. I started harvesting them and then stopped halfway through realizing they should be more yellow than green. I panicked because my tiny sample pH tested read 4.3...but I'm open to the possibility the test sample was too small and it didn't get a good read. We are extremely hot this summer and I picked my marquette grapes this week. Was surprised they where ready this early. This is really my first semi- good year for both. My PH test on the Marquette was 3.3 so I figured they where good. So basically I'm wondering can La Crescent be ripe but pretty green still? Poor sun light? Or are they just not ready and I pulled a trigger too soon?
