Cold brew is a method of brewing coffee that involves steeping coarsely ground coffee beans in cold water for an extended period of time, usually 12-24 hours. This slow extraction process results in a smooth, low-acid coffee concentrate that is typically served over ice. Cold brew is known for its rich, full-bodied flavor and is often favored for its milder, less bitter taste compared to traditional hot-brewed coffee. It has become increasingly popular as a refreshing and convenient way to enjoy coffee, especially during warmer months. **

The Caffissimo may brew only lukewarm coffee due to several reasons. One possible reason could be that the water temperature in the machine is not hot enough to extract the full flavor and aroma from the coffee grounds. Another reason could be that the machine's heating element is not functioning properly, leading to a lower brewing temperature. Additionally, if the coffee grounds are not fresh or the grind size is too coarse, it can result in a weaker and lukewarm brew. **

Alternatively, you can also brew tea without a tea bag by using a tea strainer to separate the leaves from the liquid after steeping them directly in the hot water. **
