Firstly, thank you Yule (I hope I’m right in thinking that this is your first name?!) for taking the trouble to start this thread. It’s an excellent idea. It’s also a lot more complicated than the red wine thread which is almost entirely about Cabernet Franc wines! I think you’re absolutely right to choose a vineyard/plot classification rather than a producer one.
I drink Loire whites almost on a daily basis, because they are such good value and because I love the style, but most of mine are entry level so not relevant here. These are just some ideas:
Chenin
There is a new wave of producers that I’m really getting into, who make their wines in a very crisp, fresh style, mostly in the Anjou appellation. I suppose that Thibaud Boudignon has been the trailblazer, but these are for me at the same level of quality, mostly at cheaper prices:
Château de Plaisance - bought by a young vigneronne called Vanessa Cherruau two years ago, who makes mostly dry wines where in the past the wines were Quarts de Chaume. I haven’t tried all of them yet, but my favourite so far is the Savennières. The wines are very precise and chiseled, but slightly softer than Arnaud Lambert’s, for example.
Domaine Belargus - along the same lines, this comprises vineyards previously owned by Jo Pithon who I think is still consulting, along with Guy Bossard. I have only tried the dry whites, which I have found to be sensational, on a higher level than those of Plaisance (and a lot more expensive). I don’t really have a favourite yet.
Bertin-Delatte - bottled as VDFs, the one I just prefer is the Vingt-Neuf cuvée, which is semi-sweet, a beguiling blend of white peach and apricot with very crisp lemon and pear flavours on the finish.
Domaine de La Renière - Saumur - I had an excellent La Cérisaie recently, again more apple and pear than honey, really good value at 16€.
La Grange Tiphaine - Montlouis - I really enjoyed Les Epinays 2017, but I’m slightly concerned by the high ABVs of the more recent vintages.
All of these would merit being somewhere in the list, but I have no idea where - I haven’t had enough yet to be certain. Also, the first two are recent creations so it is too early to say how they will age (and whether the standards will be maintained in subsequent vintages).
Domaine Champalou - Vouvray - this one I do know well. I have been buying their wines since the mid-90s. I wouldn’t say they are quite at the same level as Huet, Chidaine or Blot, but their wines are excellent nonetheless and better value. The style has always been softer - “tendre” - and I think the best is Les Fondraux which is “officially” semi-sweet. The style has changed since 2016, I think, into something crisper than in the past, with more apple and pear flavours and less honey. At 16€ this is much better value than the other more prestigious names. I think the Fourth Growth level is probably appropriate.
Jacky Blot - I’m surprised he hasn’t been mentioned. Unlike the reds, I’ve slightly lost touch with the whites over the last few years, because of the competition. My favourite is Clos de la Bretonnière but maybe there are better ones now?
Muscadet
Domaine de la Pépière - definitely my favourite producer, but I’m not sure which wine is the one I prefer. I love Les Briords but also the crus, with perhaps a slight preference for Thébaud. I’m sure others have better suggestions.
Famille Lieubeau - not at quite the same level, but not far behind. The Thébaud 2015 I had recently was sensational, better than the Pépière 2017.
Bonnet-Huteau - same level as Lieubeau, but I am not sure which wine to choose. Perhaps Les Gautronnières?
Jo Landron - another contender for at least the second level, but which wine? I would go for Haute Tradition but others I’m sure will have more experience than me.
Anyway, just some ideas for discussion!
