So I have a connundrum - We are planting this spring but did some math wrong and have space for 14 more vines. Was thinking about doing something different for fun (Gruner Veltliner) - but what could one reasonably expect to yield from 14 vines? We are planting about 150 total, the rest are all reds - mostly Cab Franc and Cab Sauv, so blending the Gruner with something else isn't an option.
