1) ESPRESSO MAKER FAQ (LINEA SUPREMA)

a) Materials & Construction

What is the Linea Suprema made of?

The Linea Suprema uses two premium grades of stainless steel:

Upper Chamber, Main Body, Filter and every part that makes contact with your coffee is made from : 100% 304 stainless steel

• Food-grade

• Corrosion-resistant

• Delivers the cleanest, purest flavor

Base: 430 stainless steel

• Specially selected for induction stove compatibility

• Magnetic properties allow it to work on all stove types

 

There is no aluminum, no plastic, no paint, and no coatings inside the brewer.

Why 304 stainless steel for the body?

304 stainless steel is the gold standard for food purity, durability, and preventing metallic taste.

Why 430 stainless steel for the base?

430 stainless steel contains magnetic properties required for induction cooking, allowing the Linea Suprema to work on induction, gas, electric, and ceramic stoves.

 

b) Brewing & Use

What cup sizes does the moka pot produce?

Italian “cups” refer to espresso portions, not American mug sizes:

• 12-cup: ~18–20 oz

How long does brewing take?

Approximately 4–6 minutes, depending on heat level.

What grind size should I use?

Use a medium-fine grind — finer than pour-over but slightly coarser than espresso.

Does it produce crema?

Yes — stainless steel heat retention enhances crema formation.

 

c) Maintenance & Care

Is it dishwasher safe?

We recommend handwashing ONLY to protect the PVD finish and longevity.

How do I clean the inside?

• Rinse with warm water

• Avoid soap inside the bottom boiler

• Let it air dry completely

Will stainless steel rust or discolor?

304 stainless steel is highly corrosion-resistant. Overtime the interior may develop a light coffee coloration from natural oils. This is normal, safe and does not affect taste. It can be washed away with soft sponge and a 3:1 part solution of Baking powder and Water.

 

d) Troubleshooting

Steam leaking between chambers?

Check:

• proper tightening of the top chamber

• filter basket placement

Coffee tastes burnt or bitter?

Common reasons:

• heat is too high

• grind is too fine

• coffee is old or over-extracted

Coffee is weak or watery?

Causes:

• grind too coarse

• low heat

• underfilled coffee basket
