"Because it's hard for people to gauge quality by flavor, they tend to gauge it by price. That's a mistake. Langstaff has evaluated wine professionally for twenty years. In her opinion, the difference between a $500 bottle of wine and one that costs $30 is largely hype. "Wineries that sell their wines for $500 a bottle have the same problems as wineries that sell their wine for $10 a bottle. You can't make the statement that if it's low-cost it's not well made." Most of the time, people don't even prefer the expensive bottle--provided they can't see the label."
