Cold Brew as the enduring summer trend in coffee shops

Cold brew coffee has become an increasingly popular summer drink in recent years for several reasons.

Although there are customers who like to enjoy a more "challenging" cup of coffee, most will happily drink a coffee on a hot summer day that has a smooth and mild taste and is pleasantly refreshing.

How to Start Making Money Selling Cold Brew

It is generally known that Cold Brew takes a large amount of time to prepare due to the long extraction time. Coffee shops usually have to create Cold Brew at the end of their shift and let it infuse overnight to achieve the desired result. However, this is very limiting and if the Cold Brew runs out during the day, there is simply no time to make a new one.

Hard Beans have come up with a revolutionary device called the Baby HardTank that puts an end to the lengthy process of making Cold Brew. In fact, it can prepare 4 liters of the desired beverage, be it Cascara, tea or just Cold Brew, in 45 minutes. During the day, the HardTank can prepare up to 32 litres of cold beverage.

Thanks to the short extraction time, the risk of oxidation is reduced and the shelf life of Cold Brew is also increased. Theautomatic cleaning programme and special cleaning products guarantee stability and safety throughout the entire production process, while significantly reducing water consumption and labour costs, as the preparation of one batch of Cold Brew in the HardTank takes no more than 15 minutes of working time.

Anothergreat advantage is the integrated smartphoneapp, which allows you to fully control the equipment, record recipes and monitor statistics and alarms.
