I'm glad you talked me into coming to this wine tasting. Tonight is special. We are tasting champagne. Where's this one from? It's from the Champagne region of France, that's where it gets its name. Only grapes grown there can make true champagne. I see, so this one which is called brut must have been made from grapes grown in a different region. That's right. The Champagne region has a cool climate, which has an effect on the wine making process. What's this one, Dom Perignon. Didn't a man named Dom Perignon invent champagne? No, he didn't invent it, but we owe a lot to him for improving it. Pierre Perignon was a Benedictine monk who, in 1688, was appointed treasurer at the Abbey of Hautvillers. So, his job was the management of the cellars and wine making. But why does champagne have bubbles? You said something about climate.
