Hi. I have two vines planted permenantly outside in the garden. One grows along garden shed, with quite a few bunches of grapes, and only been growing for 2 years.
The.other planted last year, again in open ground, but stem through into my shed extension, which is walk through, minus doors, to permit access to the top part of the garden, made from Perspex which is basically an open cold frame, about 8ft high, and similar width and length. Vine now being trained along wires etc.
I have seen several greenhouses on local allotments, with vines planted outside, but stem through a missing glass. Even some garden centres have similar within their restaurant extensions, with plenty go grapes growing well
Hampton Court has a vine growing outside, stem inside, many hundreds of bunches grapes this year, and reputed to be over 50 years, (from memory, maybe even more)
Most vines are hardy, so should survive outside ok.
