How Champagne, Prosecco and Cava differ in where they come from, how the bubbles are made, what Brut or Extra Dry means in grams per litre, and why the bottles are sealed differently.
How wine aging works: what oxygen does, how oak barrels, steel tanks, concrete eggs and the bottle compare, what lees aging means, and what aging words on a label tell you.
