It was time to test the grapes and decide if I needed to start harvesting yet. I got out my trusty refractometer to see what the sugar levels were at.
There are a number of factors involved in deciding if it’s time to harvest grapes. It’s a balance between grape quality and suitability and readiness for winemaking. And it also all depends on the season–whether you got a lot of rain or very little. This was a great season for my grapes because we didn’t get any rain for the first three months of grape development, so the fruit got really sweet and the acid levels had the chance to lower somewhat.
