Quick Summary

Vacuum brewing is a coffee-making method that utilizes steam pressure and vacuum to brew coffee. In this process, heated water is pushed from a lower chamber into an upper chamber containing coffee grounds. Once the heat source is removed, the steam condenses, creating a vacuum in the lower chamber. This vacuum then draws the brewed coffee back down through a filter into the lower chamber, ready to drink. This method is one of several ways to extract flavor from coffee beans, alongside steeping, percolation, drip, and espresso methods.12
