Welcome to the re-invention of the Aeropress. The Aeropress Go! is a compact version of the original Aeropress. All of the parts, you need on the go, that will fit neatly inside the 400ml cup. I can think of a number of our clients that like to bike across the UK and beyond and every so often, they stop, get the gas stove out, and make coffee.
Without making this a really wordy description, there are various ways of making Aeropress and the designer; Alan Adler has his own methods. James Hoffman has a different take on the Aeropress Go. Both are worth watching as they are dramatically different. I would watch Alan’s video first, I would just avoid the micro-waving bit at to 130 degrees at the end. Bless.
