Key benefits Reduces bitterness and improves the taste of espresso by lowering brew temperature without diluting the drink. Cools espresso quickly while preserving the original flavor and crema because no water is added. Comes with a dedicated storage box to keep cooling balls clean and protected in the refrigerator. Features and performance Designed specifically as espresso cooling balls that provide a cooling effect without changing the drink's taste. Performance: when fully frozen, the cooling balls can reduce espresso temperature by approximately 80–100°F. Includes a bracket so you can position the frozen ball over a mug and allow coffee to flow through the cooled surface. Simple to store and hygienic refrigeration thanks to the provided storage box. Compatibility and use Intended for use with espresso and other brewed coffee where a moderate temperature reduction is desired. Not designed to make iced coffee. If you need to significantly lower the overall temperature of a large volume of coffee, you will still need to use ice cubes. How to use (quick steps) 1. Place the cooling balls in the freezer until fully frozen. 2. Set a frozen cooling ball into the bracket and position it over your mug or cup. 3. Start your espresso or coffee machine so the hot espresso flows over the frozen ball and is cooled as it passes into the cup. Practical use scenarios Pulling a singleshot espresso that's too hot to taste immediately: cools the shot quickly so you can judge flavor without waiting. Preparing a short Americano or lungo where slight cooling is needed but dilution must be avoided. Tasting multiple espresso shots during cupping or home testing without letting heat mask flavor differences.
