I've been out pruning the vines, even in the snow, as they need to be done while dormant and before the sap starts to rise. As you can see from these recent pictures, this is quite a brutal process, cutting out all of last year's growth except for 2 canes, which are then laid down and tied to the main training wire. This training method is known as 'cane replacement' or Double Guyot. It is the main training method used in most large vineyards but was not practised in England until relatively recently - the 'spur pruning' of a permanent vine cordon was the previously favoured method as it was much simpler for the amateur vineyard owner to use. I've found over the years here however that these permanent cordons tend to stop producing grape-bearing canes at various points along the cordon and so I've switched to Double Guyot - or indeed Single Guyot in the new vineyard.
