Since English is not my mother tongue, I couldn't understand what "mid-range red wine" is. Can anyone help?

For sangria, a decent (i.e., not costly) Rioja is the obvious choice, but I also think Beaujolais works well. I definitely would stay under $12 (tops) for sangria - actually, last summer I made several tasty batches using a ridiculously inexpensive Sangiovese from Trader Joe's (rec'd by a friend who knows much more than me about wine.) Relatively soft tannin, fruity - just ok on its own, but worked well in sangria.

Thanks, June!

Since it's in regard to Sangria, it may also mean mid-range as not too dry, not too tannic. When making Sangria, I look for wines such as Beaujolais or Barbera that are fruit forward and have soft tannins. These wines also generally fall into a mid-price range, but I look for them to cost between $8 and $12 for Sangria.

Thank you so much for the answers! I should have realized it was price range!!!! :-)

It means mid price range. Something inexpensive but decent will do for sangria.

Most likely it means the price range. Something not too cheap (and poor in quality) and something not too expensive. Try for wines in the $15-$30 range. You don't want a bad tasting wine and you don't need to use an expensive higher quality wine. Use a red that you like to drink on it's own and you should be fine.
