GSI Mini Espresso Set 1 Cup - £51.50

Starting off with the coffee makers that require a heat source, we have the GSI Outdoors Mini Espresso Set 1 Cup.

First point to make, this makes a very generous single shot - a bit more than a double. Enough that I'm happy to share it, although that does leave you both with a coffee that's on the small side.

In essence, GSI's Mini Espresso works just like the original octagonal moka pot:

1. Add water to the base.

2. Fill the basket up with coffee and scrape it flat with the side of a spoon.

3. Put the basket in the base.

4. Screw the top on.

5. Heat until coffee stops coming out the spout.
