How Temperature & Grind Size Work Together
We find that many people do not make coffee cold at home. That is more something they purchase from a local shop. But knowing how brewing cold changes your grind settings will give you the power to make a delicious cold brew at home. When you brew coffee with cold water, it changes the extraction process. In fact, the extraction process is much slower. Imagine sticking a green tag bag in a cup of cold water and another in a cup of boiling water. The cup of cold water is going to take a much longer time to extract and show the color of the tea. The same is true with coffee.
The rule of thumb with colder brewing temperatures is that it usually calls for coarser (larger-sized grinds) and longer brew time. The inverse is usually true as well. Warmer temperatures call for shorter brew times and finer coffee grounds.
