Just out of curiosity what grapes are you growing, and why. And how many do you have??
I have Barbera, Alicante Bouschet, Merlot,Cabernet Franc and Criolla Mediana 123 total vines not including criolla which I have about 63 vines now. I've been slowly planting more of it.
Can't wait for the vines to mature I will get a bunch or criolla this year from 40 year old vines. I expect it to make a decent light red wine from the little information avaliable. As it's not a very well documented grape with very low plantings in California. I will be the only person making a wine that's 100% Criolla Mediana in the State.
I can't wait for the Merlot and Cab to mature I intend to go ahead and do a blend of around 70% Cab and 30% Merlot when they mature. The Alicante and Barbera will be single varietal wines. Although I might adjust color with some of the Alicante.
Also I figure I'll also ask what other grapes would grow well in Sandy soil, I have a climate nearly identical where I live to the Rhone region. I've been thinking about adding some white wines. I should also add that my property is on hilltop that gets lots of sun and a good breeze.
