The Mystery Persists
I still haven't heard anything from the grower about what the mystery vine might be. As you can see below, they are quite different. I have removed the grow tubes upon the recommendations of other winemakers, as I don't have persistent critters. I should have protected the vines when they were smaller., but they seemed to have made it OK.
Also some of the little Syrah grape blooms that I let hang around are starting to show fruit. It is tiny compared to the older vines I have seen at local wineries, but it's nice to see that our vines actually produce fruit.
