A section of a wine list is a collection of wines that are grouped together based on their type, such as reds, whites, or sparkling. Reds are wines made from dark-colored grapes, such as Cabernet Sauvignon, Merlot, and Pinot Noir. These wines are typically full-bodied and have a higher tannin content than white wines. Reds are often aged in oak barrels to give them a more complex flavor profile.
