Whenever I pull the capsule off a bottle of wine, and I see a rubber stopper, I'm instantly jaded against the wine. I try not to jump to conclusions based up packaging, but I can't help it. I'm biased against synthetic 'corks'. I know some people, I'm sure you know them too, who choose wines based upon whether or not they like the label. In the same way, I specifically try to avoid wines sealed with rubber stoppers instead of a natural cork. I feel like when I see a rubber stopper, the winery just doesn't care about the wine. Wine makers that give a damn about their wine use twist tops, or natural cork. What do you think? Are you biased about stoppers, labels, bottle shape, whatever?
