Poor hygiene
Manual cleaning leaves room for mistakes and microbiological growth.
Oxidation
The long extraction time increases the spoilage risk with microbiological & quality issues.
Lack of consistency
Oxidation & manual operations increase the risk of poor quality.
High operational cost
Paper filters, long draining & cleaning times, and high levels of waste.

Frequently Asked Questions

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.
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.
Yes, we offer Hardtank models with built-in tap systems to serve nitro cold brew.
However, the Baby Hardtank requires a separate dispenser.
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.
All Hardtank devices have automatic cleaning and sanitation modes. These are easy to activate and extend the lifespan of your device.
No, Hardtank technology offers exceptional brew quality without the need for any single-use filters.
You can brew up to five litres of cold brew with the Baby Hardtank, and up to 18 litres with Hardtank 20.
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.
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.
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.
Assuming a 200ml serving size, you can brew 300 portions per day with the Baby Hardtank and 1250 with Hardtank 20.
