The Aeropress has proven itself as the go-to device for personal coffee brewing. Easy to use, easy to clean – perfect for travel. We find that the Aeropress works best with a double shot of ground coffee, brewed to the number 2 line, stirring well before plunging the top down. Add hot water or brew over ice, it really is hard to mess it up. It is made from BPA free plastic so it packs light. Virtually every Redshift inter-dimensional traveller swears by this device and it is considered a necessary item before any trips to Java2.
