Getting close on some vines!
Update on things, the Marquette is just about ready to harvest. I noticed some very guilty looking birds hanging around the vines these days. I can't tell if they are snacking on grapes or not. If they are so far its not too noticeable. I made a quick trip to ABQ on Sunday afternoon to pick up my free bird netting. One of the old timers of the NM Vine and Wine Society had some used stuff that he said had some tears in it but there are some good sections as well so I should be able to cobble enough together to cover the vines by this weekend at the latest.
I picked up an inexpensive refractometer from Amazon and pulled it out yesterday after work. I took four sample berries from 4 different Marquette vines. I zeroed the refractometer with distilled water. It was just a touch off from the factory setting. The very first berry from a vine way in the back of the garden (which is a very sunny and hot location) came in at 25 Brix!
I thought holy cow, I need to pick them all today. Then I checked 3 other vines. They are all in slightly cooler and a little more shadier areas. They came in around 19-21 Brix so they will need a little more time.
The really cool part of this whole quick little experiment was to be able to test each grape, get a Brix level and then eat what was left and see what it tasted like in the mouth.
The 25 Brix grape was pure sweetness. No tart at all. The 19-21 Brix grapes were all sweet but nowhere near as sweet at the 25 Brix grape plus they had a slight tart taste to them still.
At some point I hope to have a calibrated mouth and won't even need the refractometer!
Will post some pics perhaps this evening,
