Have you ever noticed that wines can taste really good at a restaurant, wine bar or especially at a winery? It's the whole experience, not just the aromas and flavors, that affect our sense of taste.
As I've discovered, a $15 bottle of wine, when served in a high-end restaurant (where they charge you $45 for that $15 bottle), will taste especially good. Somehow, the lavish surroundings, the great service and the wonderful company at the table just makes the whole wine experience so much better.
And, at a winery it can be even more powerful. You are typically in a beautiful setting surrounded by vineyards and being served by someone who is very knowledgeable about the wine or maybe even the winemaker. This experience can significantly heighten the taste of the wine.
This fact is well understood by the publications that do wine ratings. So much so, that they don't allow their tasters to review or rate wines at wineries or restaurants. They ensure their tasters are in a neutral setting in order to allow them to focus only on the wine (which, by the way, they are tasting 'blind' with no knowledge of who produced the wine or what it costs).
So, keep in mind that the amazing bottle of wine you recently had at that fancy restaurant was probably made even better by all the other glamour around you. And, that's exactly what the wine experience is all about. Cheers!
