I’ve just planted (this weekend) my little vineyard at the allotment - 3 Chardonnay, 3 Pinot Meunier and 4 Pinot Noir; a classic mix used by Nyetimber, amongst others! The buds were just breaking on the Pinot Meunier - a lovely pink tinge to them - while the Chardonnay were more advanced at about 10cm long. Typically, the PN was still in bud.
The stems were about 10 - 12mm diameter, 15cm long and the grafts well covered in green wax through which the buds burst forth. I have great hopes, at least to be able to make Dolmades! Good grapes will depend very much on training and pruning, I suspect. One problem will be the fertility of the soil - likely to be high and encourage growth rather than fruit.
Give it 5 years and there might be a new fizz to try!
