My average bottle of wine is usually between $10 and $15 a bottle. I could not possible give up the grape so I had to make adjustments. There are a couple of nice wines in that price range.
I will always continue to buy the Mollydooker wines, but there are a few great wines that I have found that are excellent and inexpensive. 05 Parsons Flat from Padthaway is an awesome shiraz blend that is fruity with a hint of oak and I bought a case at $17 a bottle. Also the Marquis-Philips wines are all very good and very inexpensive. Just had their 06 cabernet that was rated 90 points and it was awesome. Paid $15 for it in Delaware. I agree with Chandra, there are a lot of good wines out there in the $10-$20 range.
