...I did once go to a cooking demo where the chef instructed his assistant to go into the larger store and grab "the cheapest wine on the shelf".
During Q and A I asked about that, always having believed that as Brad says, cook with what you drink.
"I only drink $ 100 wine" says he.
Well ok, not me. WSo I go with anything around $ 10 and I keep it in the fridge. Now, sometimes when we run out of the better stuff we'll drink it, but that keeps the supply fresh...
