We were staying in the Gruene area and stopped at The Grapevine for their wine tasting. The bartender was very pleasant and offered 3 free tastings. They had a table with wine marked down to 50% off. I selected the only bottle of Sauvignon Blanc from New Zealand but there was no price tag on the bottle. The bartender swiped the UPC code but questioned the price that was shown. So he took the bottle to the owner who was in her office. She came out and picked up a red bottle of wine from the table, scanned it, and said all the wines were $25 so the selling price would be 50% off of that amount. I should have questioned this sales tactic. The next day I learned that the retail price of this particular bottle was $13 and that was likely the price that showed up on the register! This shop has unconscionable business practices so I agree with the previous reviewer who suggested buying your wine at HEB.
