01How does AstroBrew make cold brew in minutes?
AstroBrew combines coffee extraction with chilling, so you can make cold brew without the traditional overnight steep. Learn more on the AstroBrew machine page.
02What is cold brew coffee?
Cold brew is coffee made by steeping grounds in cool water rather than brewing them with hot water. Traditional cold brew takes a long steep; AstroBrew is designed to make a batch in minutes.
03How does the brewing process work?
AstroBrew uses turbulence, pressure, and recirculation to accelerate extraction. The system brews and chills together. See the machine page for product details.
04How much cold brew does one batch make?
A batch makes about one liter of cold brew. Visit the machine page for current product details.
05Do I need to add ice?
No ice is needed for a chilled pour from AstroBrew. Add ice to your glass if that is how you like to serve it.
06Do I need special pods or coffee?
AstroBrew is made for coffee grounds, so you can bring the coffee you enjoy. See the machine page for product information.
07Can I make iced tea? What about sweeteners?
AstroBrew can also be used for beverages that need steeping or chilling, such as iced tea. Do not add sugars or sweeteners to the brewer: they may damage the machine and may void the warranty. Check the instructions and warranty for your specific unit.
08How should I clean AstroBrew?
The coffee filter is removable for cleaning. The secondary filter protects the pump, is removable, and should be cleaned monthly. The container interior can be wiped with a cloth dampened with warm water and soap. Unplug the appliance before cleaning and follow the instructions supplied with your unit.
09Where can I find current shipping information?
