I feel like planning is virtually impossible! There is no way to know when grapes will be ripe, what grapes will be available and what my schedule will look like! With that said, I have goals, rather than plans. Plans will need to wait a few years until I semi-retire.
I honestly think most "Field Blends" these days are a myth. They are fermented separately and then blended. The one notable exception I know is the Lytton Springs vineyard at Ridge. That vineyard has numerous red grapes (Zinfandel, Petite Syrah, Carignan, alicante, mourvedre) all randomly planted in the same field and harvested at the same time.
For 2020 my goals are: (aiming for 60 gallon total production plus or minus)
Primitivo/Zinfandel-This will be my 4th year making grapes from this vineyard and since it belongs to a friend, there's always a friendly wine competition on pick day.
Cabernet Franc-This will be a new one for me, but
@NorCal is managing the purchase and I'm hoping to buy 1/2 ton (split with 2 other wine makers).
Sauvignon Blanc-This is a request from my wife, no source of grapes yet, but working on it. White wine is new territory for me.
Syrah-A maybe this year, but since I have vintages from '18 and '19, I'd like to keep the vertical going.
Wish list for 2020-
Barbera-One of my favorite food wines
Rose-Was fun and tasty 2019-
I'll be opportunistic depending on what is available in September and October.
Good luck everyone!
