Almost anything you find on shelves of your local supermarket is going to be heavily procesed industrial wine. The price itself will determine use of more expensive/time consuming proceses, but at the end they are all just drink products.

If wine is just a drink for you than there is huge amount of good wines for $10 - $15. Nicely done, good products.

For me, huge wine nerd (and also owner/winemaker of small organic winery) the wine is more like a postcard from faraway place and book of poetry at the same time. I am sure I am not going to be able to tell difference between cheap and expensive wines sometimes, but that is not a point. There is a more into wine than primary aromatics if you want to dig deep into into.
