I usually drink $6-$15 bottles of wine, trying new things probabyl 1/2 the time and coming back to old favorites routinely, mostly Aussie wines.
A new U.S. one we've been buying more commonly is Crane Lake. Don't be put off by the price, its only $3.50-$4 a bottle, but very good.
My wife loves their Cab for reds and their Pinot G for white, and I really like almost all of it, (just nothing too dry to where a I pucker up or too sweet to were I get a sugar headache after one glass.)
I was told, purely rumor, that Crane Lake is so cheap becuase the wife got mad at the husband for whatever reason, they had a split and she got 1/2 the winery and is now selling dirt cheap, but purely rumor thus far

I was also told that it is made by the same people that make two buck chuck for Trader Joes, but we don't have a Trader Joes, so again, purely rumor.
