Until about 10 years ago, it was difficult to find a place in the United States that served iced coffee. To them, coffee was something that should be hot. For them, coffee was something that should be served hot, like a small basket of soup for Japanese people, and it was unimaginable to have it cold.

But when I visited the U.S. this year for the first time in many years, I was surprised. Iced coffee was sold as a matter of course. Not only was it on the menus of cafes, but it was also sold at fast food restaurants such as McDonald's. It seems that iced coffee is also available in the United States. It seems that the iced coffee boom has (finally) arrived in the United States.

The iced coffee boom (?) has recently been gaining momentum in the United States. In response to the iced coffee boom, the Zoku Iced Coffee Maker was recently launched in the United States. This is an item that can easily make iced coffee at home.


To make iced coffee with the Zoku Iced Coffee Maker, a special mug is placed in the refrigerator to chill. Pour freshly brewed hot coffee into the chilled mug, and iced coffee is ready to drink.

This mug is made of stainless steel with low thermal conductivity, the same material used in water bottles and thermos bottles. However, the thickness of the mug is different from that of a normal water bottle or thermos. It is several times thicker, and this keeps it cold in the refrigerator. It functions like ice and cools the hot coffee for a moment after it is poured. Since the coffee stays cold afterwards, it can be taken out with the lid on.


Put the mug in the refrigerator at night before going to bed and pour freshly brewed coffee into it in the morning. You can take it to work and enjoy a cup of delicious iced coffee at the office. This is quite a nice lifestyle, isn't it?

The product is sold at Williams-Sonoma's mail-order website and is listed at 3,595 yen. But unfortunately, it does not seem to be available for delivery to Japan.
