After many years of buying the occasional bottle of wine, I have recently purchased my first case of wine and have almost finished it off. I tend to like Carbernet Sauvignon with steak, but I prefer a Merlot for pure drinking before or after a meal. The case I purchased was a blend called Chateau Lafite Rothschilde Reserve. I found it suitable for before and during the meal, but the bitterness seems to build up and I have a difficult time finishing the bottle without chilling it.
I'm specifically looking to put together a sampler of similar, but hopefully better, wines to try out, and so I am looking for some suggestions of such wines that are daily drinkers under $20 that are "drink now" and also widely available, such as at Specs. I'm finding that most of the wines rated here are not available at Specs, and that the wines listed on the Specs website tend not to be rated here, so I am looking for personal recommendations, with an eye towards price and availability. If you personally would not recommend a wine under $20, what would you consider a minimum price level to recommend, and which wines in particular?
