Today I didn't have a lot of time to pick, so I just did 10 Leon Millot vines to get a feeling for how they were doing. AWESOME- THAT"S HOW!
Like I said above, the one vine had 41.4 pound on it. I am beginning to think that there has been too much emphasis on cutting yields to impreove quality. The vine above is in an extra control panel next to my SARE research trial - handled identical to the rest of the control for that variety. I initially pruned to 5 shoots per foot split between the top wire and the lower wire using a 4 arm-kniffen system. Being the control, they received no additional shoot thinning or cluster thinning like the shoot thinned section or cluster thinned section. The vine had 279 clusters on it! Holy crap batman! So you don't think it was unusual, the other vines in that section averaged 35.2 pounds per vine!
You might say- yeah but what about the quality? They taste great- a very few green shot berries, but I ran the labs on them and what do you think?
Brix 22.0, pH 3.14 and TA 6.8g/L or .68 depending on your scale you are used to.
The two sections I picked were in different areas of the vineyard. They both tested very similar, but the western one yielded more. The eastern one is on pure sand. The sandy one averaged 25.4 pounds per vine or 8.6 tons per acre. the western one averaged 35.2 pounds per vine or 12 tons per acre. I ask myself why we insist on thinning to 3-5 tons per acre when you can get great numbers at twice the yield using the right varieties and training system. This is the basic premise I am working with in my NE SARE grant work.
So Al - believe me when I say- you ain't seen anything yet for yield- wait until next year when the vines are a bit more mature.
