AstroBrew is a brand new startup founded by a former Keurig Dr Pepper Thermal Engineer. AstroBrew believes in strong high quality products, and manufacturing takes time. Please support AstroBrew as much as possible as we work hard to manufacture your revolutionary cold coffee brewer.
Cold brew coffee is brewed using cold water for an extended period of time, typically 12 to 24 hours. This slow, low-temperature extraction process results in a coffee that is smooth, less acidic, and more concentrated than traditionally brewed coffee. Widely considered healthier than hot-brewed coffee, it is the fastest growing beverage sector in the world.
Extracting the flavors from coffee grinds with boiling water can result in the release of acids. It's like punching coffee in the face. This is why hot coffee tastes so bitter.
Cold Brew slowly steeps the grinds in stagnant water and prevents the release of acids that cause heartburn, indigestion, and poor gut health.
AstroBrew's patented brewing technology speeds the process up from 24 hours down to 5 minutes. Amazing!

No ice required. AstroBrew automatically chills your beverage as it is brewing and maintains the temperature indefinitely. In fact it is more energy efficient than your refrigerator.
However if you are drinking your cold brew on-the-go, we recommend ice to keep your drink colder for longer.
