Three-cup Bialetti Moka

I have a teal three-cup Bialetti, and she's cute. I want to get a bigger stovetop espresso maker, to be honest, because my new weird habit is making large amounts of espresso to store in my fridge and make into iced coffee drinks on the fly. I am hiding this habit from my boyfriend because I think the concept of batching espresso might cause a breakup.
