Description
An iconic example of Italian industrial design, the Moka Express is celebrated for its distinctive octagonal silhouette and pressure-based brewing method. While appearing metallic or silver-toned, it is made of aluminum to ensure rapid heat conductivity.
Key Features
The 'U12' stamp identifies this as one of Bialetti's largest residential models (12-cup capacity). The 'Man with the Mustache' logo is a primary authentication feature.
Material & Composition
Food-grade cast Aluminum (not silver); non-magnetic base and lightweight composition typical of aluminum alloys.
Finish & Decoration

Hallmarks & Stamps
Stamped 'MADE BY BIALETTI SINCE 1933', 'U12' (size indicator), and 'ITALIAN QUALITY & DESIGN' with the trademark mascot.
Construction Details
Die-cast aluminum components with lathe-finished base; octagonal faceted body designed for structural integrity and heat retention.
Functional Features
Internal safety valve, central hollow stem, funnel filter, and gasket-sealed screw mechanism.
Handle & Grip Details
Heat-resistant thermoplastic (Bakelite style) handle and lid knob, typically black and ergonomically curved.
Craftsmanship Details
Machine-cast and finished; consistent with mass-produced industrial kitchenware rather than artisan-wrought silversmithing.
Authentication Indicators
The presence of the original mascot logo and 'U12' sizing mark are consistent with genuine Bialetti mass production.
Origin & Manufacturing
Designed in Italy; manufacturing by Bialetti Industrie (Crucinali, Italy or international facilities depending on year).
Era & Period
Modern Classic (Mid-Century Modern roots, 1930s Art Deco aesthetic carried into contemporary production).
Age Estimate
Modern production, likely 21st century (post-2000s) based on specific stamp typography and mascot design.
Cultural Significance
Recognized as a masterpiece of modern art; included in the permanent collections of MoMA and the Science Museum in London.
Condition Notes
Fair to Good; shows heavy surface usage, oxidation spots, and carbon scoring on the base. Requires specialized cleaning to remove calcium and coffee oil buildup.
Value Estimate
$30.00 - $60.00 USD (Second-hand market value; significantly lower than silver due to base metal composition).
Care & Maintenance
Hand wash only with warm water; never use soap or dishwashers as the alkaline detergent will pit and discolor the aluminum. Do not use steel wool.

Interesting Facts
The design was inspired by Alfonso Bialetti's wife’s laundry machine (the 'lisciveuse'), which used a similar boiling/rising pipe mechanism.
