Jos some truth in your remarks but where we currently excel is fizzy dry wines. We do not quite get the ripeness into the grapes to make good still wines. The fizzy wines get some sugar added for the secondary fermentation and that is what makes them so good / respectable
The guy at Leyerthorpe ? near Swillington on the outskirts of Leeds does a very respectable fizz but I can buy cheaper champagne not to mention the Italian fizzes and Cava which are significantly cheaper. I've yet to taste anything I liked from Holmfirth either
Penny black from the vineyard in Staffordshire is ok and still but not better.
I'm happy to take suggestions for good still English wines and give them a whirl. Proof of the pudding is in the drinking in this case
You are correct there, re the sparkling dry and that was what I first had, a bottle of Nyetimber which started my curiosity. Re still whites, the range we can grow you are correct is limited, but I absolutely love Bacchus, which grows really well here. I'm lucky to live in Southern England and have a few Vineyards in driving distance, which makes a nice alternative to a pub beer garden after a drive out on a sat/sun.
Funnily enough, the only English white I didn't like was a Yorkshire based one, I picked up from a farm shop just north of York. Layerthorpe sounds familiar but unless he's had a reband (quite possible) the label was very different and had a big Yorkshire rose on it. edit - it was this vineyard, I wasn't too keen on. But then again it was only one bottle so who knows -

I've linked through to a few of my favourites that I have tried (all Bacchus) if you want to try them. You sound like you know your wine, so would be keen to know your thoughts, especially if it is that you haven't had a Bacchus previously but have had bad experiences with other grape varieties.

http://www.chafor.co.uk/our_wines.html - You can get from Waitrose if you do an online shop. (they had a nightmare with late frost last year so as far as I'm aware, no 2020 harvest at all, unfortunately)
https://www.chapeldown.com/collections/shop-all/products/bacchus-2020 - Think you'll be able to get from Waitrose and maybe some other supermarkets.
