What is a key feature of a Double Torture Freeze?

A key feature of a Double Torture Freeze is that it includes two shots of espresso. This characteristic is significant because the Double Torture is known for its strong coffee flavor, which is enhanced by the double shot of espresso. The additional espresso not only amplifies the caffeine content but also enriches the drink's taste profile, making it a favorite among coffee enthusiasts who appreciate a bolder flavor.

The other options do not accurately represent the Double Torture Freeze. For instance, the drink does contain caffeine due to the espresso, so it cannot be said to have none. Additionally, while variations of the drink might include different types of milk, oat milk is not a defining characteristic of the Double Torture Freeze. Lastly, the drink is not limited to just a small size; it is typically available in various sizes to cater to different preferences. Thus, the inclusion of two shots of espresso is what makes the Double Torture Freeze distinctive and highly sought after.
