I have heard a lot of people say that they are not wine connoisseurs and cannot tell the difference between cheap and expensive wines. So this past Saturday night I decided to conduct a little unscientific test. At 4:30pm I decanted two bottles of Australian Shiraz, 2003 vintage. One bottle cost roughly $10 and the other cost about $40. At 7:15 I poured the wine in glasses and briefed the test subjects:
“One of these wines cost $10 a bottle, the other cost $40, can you tell which is which?”
Three out of the four subjects were able to tell almost immediately which was which.

Hi Tim,
My fiancee’ and I JUST did this same thing in Barcelona a couple of weeks ago. Asked the grocery store “wine guy” to reccommend a good big local Catalured from Catalunya. He steered us to a 20 euro wine ( about $30). Then we picked up another local red on sale for 2 euros (approx $3).
We blind tested ourselves… We both knew in a split-second which was the more expensive! Ironically, we didn’t like either. When we mixed them together our “blend” was better!
I just did a little home blending myself, mixing the Mitolo Reiver shiraz with the Cameron Hughes Lot 76 Cabernet. It was the remnants of both bottles, made a nice big glass. Thanks for commenting!
