Which of the following is NOT a type of espresso offered?

The option identified as the answer, Cold Brew, is indeed not a type of espresso. Espresso is a concentrated coffee beverage brewed by forcing hot water through finely-ground coffee under pressure, producing a rich, bold flavor.

Cold Brew, on the other hand, is a different coffee preparation method that involves steeping coarse coffee grounds in cold water for an extended period. This process results in a smoother, less acidic coffee beverage that is served cold, distinguishing it significantly from espresso.

Decaf, White Coffee, and Private Reserve are all varieties or preparations that pertain to espresso. Decaf espresso refers to espresso that has had most of its caffeine removed. White Coffee is typically a lighter roast that can be used in espresso beverages, and Private Reserve is often associated with a specific premium blend of coffee beans used to make espresso. Understanding these distinctions regarding coffee types and preparations is crucial for providing excellent customer service in any coffee shop context, including Dutch Bros.
