I ordered a 1 cup Bialetti Moka Express from Amazon after reading a blog post on Jerome's Bikes. When the package arrived, I opened it and was surprised at just how small the little Bialetti actually was. It's a true one-cup espresso maker. I've made about four or five cups of espresso at this point, I'm still trying to work out the proper grind but so far everything I've made has tasted great.
The Bialetti 1 cup Moka Express. It's tiny, my little girl thinks it's adorable.
The top portion unscrews, you add water to the bottom container and place coffee in the basket.
