As Sortes is a very serious wine. Definitely comparable to Burgundy at twice the price.
As usual in this country we are usually confined to the bargain basement - no one imports the good stuff, apart from the big names like Palacios. You aren’t going to find a quality godello under 15 quid.
Avanthia is excellent, as is Raul Perez (yeah, him again) Dona Claudina (which is part Dona Blanca). A bit further down the quality spectrum, Valdesil are good, as is Palacios" Louro. There is good stuff from Ribeira Sacra too - Algueira, for example.
I agree about the warm years (though less so in Ribeira Sacra than Valdeorras - and especially Bierzo). In fact I don’t rate Bierzo godello as highly in general.
I don’t think ageing is necessarily the point. This is a very English obsession
