Coffee and the brewer
Cold brew questions
01What is cold brew coffee?
Cold brew is made by steeping coffee grounds in cool water instead of brewing them with hot water. It is a simple way to enjoy coffee served cold.
02Can I use my own ground coffee?
Yes. AstroBrew is designed for coffee grounds, not proprietary pods. Choose a coffee you already enjoy, then refer to the machine page for product details.
03Can AstroBrew brew iced tea?
AstroBrew can make beverages that require steeping or chilling, including iced tea. Do not add sugars or sweeteners to the machine: they may damage it and may void the warranty. Check the instructions and warranty for your specific unit.
04How long does a brew take?
AstroBrew makes cold brew in about five minutes. See the machine page for the latest product information.
05Is the coffee chilled when it is ready?
AstroBrew brews and chills in the same process, so the coffee is ready to pour chilled. You can still serve it over ice if you prefer.
06What is the batch size?
AstroBrew makes about one liter per batch. Check the product listing for current specifications.
07How does the brewer speed up extraction?
AstroBrew’s brewing process combines turbulence, pressure, and recirculation to accelerate steeping. Visit the machine page for more product details.
08How do I clean the brewer and filters?
The coffee filter and secondary pump filter are removable for cleaning. Clean the secondary filter monthly, and wipe the container interior with a cloth dampened with warm water and soap. Always unplug before cleaning, and follow the instructions supplied with your specific unit.
09Where can I find the refund policy?
Refund terms can change. Please consult the current refund policy for the terms that apply to your order.
