Frequent Asked Questions

Discover answers to common queries with our concise FAQ section, addressing key concerns and providing clarity on various aspects of our products/services.

What beverages can I brew with Baby Hardtank?

You can make cold brew coffee, tea, cascara, cocktails, and even infuse spirits with herbs and fruits to create entirely unique beverages. The only limitation is your imagination.

Can I infuse spirits with my Baby Hardtank?

You can. All spirits up to 60% ABV can be infused in the Baby Hardtank. Please note: you should only use spirits with lower sugar levels, as thick/viscous liquids can damage the machine.

Can my Hardtank machine dispense nitro cold brew?

Yes, we offer Hardtank models with built-in tap systems to serve nitro cold brew. However, the Baby Hardtank requires a separate dispenser.

Do Hardtank machines work without a permanent water supply?

You can fill the Baby Hardtank either manually or by using an external water pump. Larger Hardtank devices, however, can only be used with a direct filtered water connection. If necessary, you can use all of our devices with external drainage vessels, provided they’re of the appropriate capacity.

Do Hardtank machines require manual cleaning or disinfection?

All Hardtank devices have automatic cleaning and sanitation modes. These are easy to activate and extend the lifespan of your device.

Do I need disposable filters to use a Hardtank device?

No, Hardtank technology offers exceptional brew quality without the need for any single-use filters.

How much cold brew will I get from each batch?

You can brew up to five litres of cold brew with the Baby Hardtank, and up to 18 litres with Hardtank 20.

How does Baby Hardtank brew so quickly?

Our patented accelerated cold extraction technology is based around recirculation. 

Water is constantly circulated and pushed through the extraction basket meaning the coffee, tea, or infusion ingredients are constantly agitated. 

Our unique basket design creates an extremely clean brew without the need for additional filtration. This method is proven to deliver a high extraction yield in a comparatively short space of time.

What water filtration system should I use with Hardtank machines?

You can use the same filtration system you would for an espresso machine or batch brewer. We recommend preparing your water according to the SCA guidelines.

Does the Baby Hardtank require any “under the counter” equipment?

The Baby Hardtank is a compact machine with a small 30x30cm footprint. It doesn’t require any additional “under the counter” accessories to be used. 

All you need is a container ready to store your cold brew once it’s brewed.

How many portions can I brew per day with Hardtank machines?

Assuming a 200ml serving size, you can brew 300 portions per day with the Baby Hardtank and 1250 with the Hardtank 20.
