Are you good at growing grapes? Advice needed

[Cathpot]

I put in two vines last year- one outside against a sunny wall and one fed into the greenhouse but with roots outside. They both put on growth last year and I left them alone. This year they are growing away but I am finding the pruning advice a bit intimidating. The outside one is a fan sort of shape and I’ve cut it back to one leading stem and 4 side stems. It has 2 currently very very very tiny bunches of about 6 pea sized grapes.

The greenhouse one has two parallel stems setting off along wires running just under the roof glass - no sign of any fruit at all.

My vague plan was to leave them alone again this year while they settle in but then RHS has pictures of lots of pruning I should be doing which- ridiculously - I am finding hard to follow.

if you are good at grapes can I have your top tips?

My harvest! I was actually over excited to get any grapes at all- and they were really tasty so I’m hopeful for the future. Thank you for all the advice , am saving this thread for future .

That's excellent for only their second year.

Welldone @Cathpot! I hope they were nice!

can i ask if anyone is growing grapes alongside their fence (urban area, standard fence separating gardens), what kind of treillis do you use?
thank you

My harvest was like @Cathpotin the second year, this was the third year’s harvest:

I recall an episode of GQT where one of the panel said 'if you don't have enough to do in the garden, get a grape vine'. There is always some pruning you can be doing. Once they are established they grow like crazy. They are very resilient and it's practically impossible to over prune them. I've had much more success with mine since I got ruthless and asked two questions: do I want it to cover this bit of wall, and is this bit going to give me grapes next year. Anything else comes straight off.
