Delamain Pale & Dry Grande Champagne Cognac 750ml which is currently 75 at K and L Wines
I'm very far from being an expert on wine, but one resource you might consider is the Wine Trials.
The authors argue that one of the main reasons why wine fans and reviewers prefer expensive, top-shelf wines to cheaper alternatives is simply because the top-shelf wines are more expensive. That taste they enjoy so much is the taste of money.
They claim to have confirmed this hypothesis with blind taste tests, in which testers regularly rated inexpensive wines more highly than expensive ones.
Whether that's true or not, the Wine Trials provides a long list of inexpensive wines which their tasters rated highly, and this list has never steered me wrong. I've enjoyed every wine I've purchased based on their recommendation--and their comparatively low prices have allowed me to spread the risk around, instead of gambling a large sum of money on a single bottle of Chateau de Prix-élevé that I may or may not like.
(Though I still do like to splurge once in a while. What's the point of having a little money if you can't piss it away?)
Of course, since I wasn't part of the blind taste test, this raises an interesting question: am I really enjoying the taste of the wine? Or just the taste of cost-efficiency?
An illusion--with intelligence! A malignant vision, with a will of pure evil!
