Having been happy with a variety of Portuguese reds in the $4 to $7 range for everyday quaffing, I'm getting weirdly curious about the 3-liter jugs of tinto for sale in the same store for $14. They don't carry a regional designation like Dao or Alentejo, and my guess is that it will be a bit thinner than the reds in the 750 ml bottles, though still better than American jugs. I'll have to save some empty 750 ml bottles for decanting though.
If I summon up the courage to take the plunge, I'll report back! :)
