Cold soaking Starbucks Citron pomelo to extract large cups of heat.

Less than 20kcal. Starbucks cold-extracted coffee is almost the lowest calorie coffee drink. The raw material is only concentrated water, and the heat of a cup is less than 20kcal. If you don't like American burning and bitterness, you can start with cold extraction, which will make the taste softer and more acceptable to most people.
