Not only coffee


Nothing cools you better than a cold beverage on a hot summer day.
With our machine, the limit to what you can create is your imagination. 

Are you into coffee? Perhaps you’re more of a tea person?

is an all-in-one solution.

You can even prepare a mind-blowing cold cascara brew. Convinced yet?

If not, imagine infusing each of those drinks with nitrogen gas which
will make them even more revitalizing. However, infusing them is up to you.



Depending on a coffee’s roast degree cold brew production time may vary. Origin is another factor that influences the flavour. You may also play around with grind size to yield different extraction results. Whether a fan of citrus, juicy Kenyan, or sweet Brazilian, HardTank cold brew gives you a wide range of possibilities.

We have good news for cascara lovers; it tastes amazing. With a nitrogen cylinder and 45 minutes to spare, nitro cold brew cascara will cover you even on an unbearably baking hot day.

Due to the presence of the tannins, it is not recommended to brew tea with hot water for longer than five minutes to avoid unwanted bitterness and astringency. When it comes to producing tea in HardTank, we suggest to prepare it for up to 10 minutes.
