I was watching a program about wine tasting last night. It said the taste of wine changes depending on the lighting. For example, a green or cool tint will make the wine taste fresh warm red tint will make it taste sweeter.
They also sound that cheaply massed produced red wine from Romania tastes better than expensive slow aged artisan wines from France and Italy, etc.
That probably depends on whether you are buying the wine in France or elsewhere..... there was a big legal case recently where several French vintners were being sued by American wine merchants as they had been selling what the French considered undrinkable rubbish to the Americans as some very expensive fancy wine..... and the Americans hadn't noticed! It only came to light through a whistle blower. The French do tend to keep the best for themselves and only send stuff they don't want abroad :)
Having an education of wine is not a joke. It makes for knowledge, & easier to choose a wine, suitable to ones' palate & delight in matching for food to be eaten.
We're blessed here for the many grape growing areas & resultant wines, which can stand against the rest most proudly.
