Blanc, Sec, and Foursquare
Hugh Johnson uses the term 'Plain Wine' in describing Gaillac in his 1983 Companion to Wine. I don't supppose he meant to compliment the wine, but here I am drinking a Gaillac Blanc Sec and finding that Plain Wine sums it up very well, and that plain wine suits me very nicely please-and-thank-you.
Lions Lamartine Gaillac Blanc Sec 07 is made with Mauzac and Loin de l'Oeil, grape varieties found in no other part of the world. Mauzac is said to impart a flavour of apple peel, but instead I find a strong taste of honey in this old-fashioned wine. It's very, very refreshing, (very very refreshing = 3+),but in a style which is a thousand miles away from Kiwi Sauv Blanc refreshing.
Update : After I decided I liked Johnson's term 'plain wine', I found another wine that falls into the category. Le Monache Bianco is a Cortese / Sauvignon Blanc / Chardonnay blend made by Michele Chiarlo in Monferrato, in Piemonte, Italia. On tastings, people find it uninteresting, but with certain foods it sings. Less fashionable, but nonetheless a useful style of wine, long may it continue.
