Stove top (Moka) Espresso - can you use them half full ?

Post date: 2020-07-02 00:55:53

I'm interested in buying a "stove top espresso"/Moka. Most of the time it will be used to make a single cup but I'm tempted to buy a three cup size jug thinking that I can just put less water in when I want a single cup. Is this something you can actually do or with a three cup jug do you need to make three cups ? Presumably the latter is slower and uses more coffee ?
