Cork versus twist off cap

[spudman]

I recently traveled on an international air lines going to europe and drank a wonderful French white wine....the name escapes me, but it was very good. When i got home, i went to a local liquor store to purchase a few bottles. I found the wine and bought several bottles for under $10 each. When i looked closely at the bottle, after i got home, i was shocked to see that the wine didn't have a cork but had a twist cap. I always thought that truly good wines were corked, not capped....anythoughts?
