Montlouis-sur-Loire appellation cuts itself loose from InterLoire
Try anything by Francois Chidaine, who's primarily working Montlouis, but also has parcels in Vouvray. About 30% lower in price than the (formerly?) great Huet, and plenty good enough to cite in the same sentence.
(I say "formerly?" due to Noel Pinguet having left Domaine Huet last year over differences with the new owner - who's vision I find less than promising.)
If you can find anymore of Chidaine's 2008 Clos Habert, leave it where it is and PM me immediately!
His sparkling brut is also a great value.
