The term "varietal" in wine terminology refers to the grape from which a wine is made. By law, the varietal wine must have a minimum of 75% of that particular grape. It is not a widely known fact that varietal wines are not always unblended, but as long as the grape stated on the label constitutes at least the requisite 75%, of the wine inside, it's all in order.

You might expect that a bottle of Chardonnay will taste the same regardless of where it was made or who made it. Surprise, surprise...
