I'm sorry, but that just isn't true. No doubt some wines cross over, but the tannins present in much red wine are notable by their absence from pretty much all white wine.

Yes, this. Red and white don't taste that similar to me.

My nose isn't great, especially compared to my wife's, but I could tell you 100% of the time if I was tasting red or white while blindfolded.

Would you be able to tell if you weren't blindfolded and it was white wine that had food colouring added to it so that it appeared as red?

Would your sense of taste overpower what your eyes were telling you?

I absolutely could do this, even with food coloring.

Please report back after confirming :)

Let's see if I can convince the wife to open a bottle of white on a Sunday night. :-)

Heh, red wine makes me a bit nauseous while white feels like honey. I shall try blindfolded one day.
