My sister (who's not very bright) told me that different wines don't really have different flavors but that they all taste the same, and that people who claim otherwise are just snobs trying to sound interesting.
This is the same person who told me that sangría is non alcoholic due to the amount of fruit that's in it.
She should look into becoming a sommelier, she's letting all that hidden knowledge go to waste.
Agree. I hate Malbec and i can tell the difference between it and say, a Pinot noir (my favorite) or a Zweigelt (my second favorite)
