The moka pot is a stovetop coffee maker that brews coffee by passing hot water, driven by steam pressure, through ground coffee. Invented by Alfonso Bialetti in 1933, the moka pot has become a staple of Italian coffee culture. Bialetti Industries continues to produce the original model under the trade name "Moka Express". Moka pots are typically made from aluminum or stainless steel. They come in different sizes, making from one to eighteen 50 ml servings.
A moka pot has three main chambers: a lower chamber for water, a middle funnel-shaped filter basket for ground coffee, and an upper chamber where the finished brew collects. The coffee brewed in a moka pot has a strong, bold flavor. While often called a stovetop espresso maker, the moka pot produces coffee at a lower pressure (1-2 bar) than a true espresso machine (9 bar). Moka pots are available from various manufacturers, including Bialetti, Alessi, and Gaggia. The Bialetti Moka Express, a classic model, is available in different sizes, with prices ranging from approximately $38 for a 3-cup model to $60 for a 6-cup model. Prices vary depending on the brand, material, and size. Moka pots are widely available online and in stores.
