I inherited 3 vines of grapes last year. I added a 4th. The original 3 did not produce this year because they have been 'wild' and needed to be cut back. The 4th is Pinot Noir grapes and has about 12 bunches on the vine. What kind of output could I get from this? Is it worth it? I only have wine kit knowledge, so beside the learning curve, I wonder if this small an output is worth trying.
