^wiemer is awesome. highly recommend. i thought it was a lot rounder and fruitier than the alsatian and german rieslings i've had.

Some argue this was critical for swinging a nation of scotch drinkers to white wine. Others argue that it is a travesty.
from what i understand a winemaker will inoculate their wine post fermentation with lactic acid bacteria like lactobacillus which turns malic acid to lactic acid and in process forms diacetyl. lactic acid is that sour tasting stuff in sourdough bread, yogurts. diacetyl especially is the taste associated with butter that was a nice factoid about the history. going to do some more reading. i've had one chardonnay made with malo but no oak. it was pretty bad. i admit i'm a phillistine at heart. the one wine that really got me interested in wines was a glass of chateau st jean's 04 chardonnay. i was pretty amazed at how it looked like green, fruity, acidic white wine but tasted like butter which i thought went well with everything else. that summer i bought two wine books (california wine for dummies, idiot's guide to wine). and somehow managed to get in the wine class. i like buttery chardonnays every now and then.
