Stainless steel cups

Main benefits

• Stainless steel does not absorb odours and helps preserve the taste of yerba mate.
• Double-walled models keep the infusion at the right temperature for longer.
• No curado needed – the cup is ready to use straight away.
• The smooth surface is easy to keep clean and resistant to damage.

Steel cups pair well with classic bombillas and suit all kinds of yerba. A practical choice for anyone who values durability and convenience.

How steel accessories work

A steel cup (cuia) is used to prepare and drink yerba mate through a bombilla, with no curing required. Fill it with dried yerba to 1/2–3/4 of its capacity and pour in water at 70–80°C.

To keep it looking good and lasting long, wash the cup with the soft side of a sponge and avoid harsh detergents, the dishwasher and the microwave. That way it will serve you for many months.

Hygiene and easy care of steel cups

By choosing stainless steel yerba mate accessories, you opt for the highest standard of hygiene, which is hard to achieve with a gourd or wooden matero. Thanks to the nature of steel, the cups do not absorb odours or colour from the yerba, so you can switch between varieties often without worrying about flavours mixing. The smooth, non-porous surface prevents the growth of bacteria and mould, and cleaning is remarkably simple – most steel accessories can be safely washed in the dishwasher or quickly rinsed under running water. It is the ideal solution for busy people who value saving time while keeping their set completely sterile.

Thermal insulation and comfortable drinking in any conditions

Modern stainless steel yerba mate accessories often use double-wall vacuum technology, which transforms how comfortable it is to drink your infusion. Thanks to excellent thermal insulation, the cup keeps the water at the desired temperature – both hot and ice-cold for terere – for much longer than classic ceramics. At the same time, the outer shell stays cool to the touch, protecting your hands from burns and eliminating condensation on the surface of the matero. This makes steel accessories indispensable when working at the computer, travelling by car or on holiday trips.

Durability of steel accessories when travelling

If you are looking for gear that will survive the rigours of any trip, steel yerba mate accessories are an unbeatable choice. Unlike fragile ceramic cups or natural gourds prone to cracking, stainless steel is highly resistant to knocks and drops. You can pack it in your backpack without worrying that it will break in transit. This rugged nature, combined with a lightweight design, makes a steel set the perfect companion for outdoor and camping enthusiasts, and for anyone who cannot imagine a day away from home without a sip of an invigorating infusion.

Why stainless steel is an eco-friendly choice

By investing in good yerba mate accessories, you genuinely take care of the environment. Stainless steel is an extremely long-lasting and 100% recyclable material, which makes it a more eco-friendly alternative to cups made of low-quality plastics. Its exceptional resistance to cracking, corrosion and deformation means that a single steel cup can replace dozens of less durable substitutes. By buying proven accessories, you reduce the amount of waste you produce while enjoying a product that keeps its properties through many years of intensive use, no matter how many infusions you prepare.

Putting together a set with steel accessories

To fully enjoy the ritual of drinking the infusion, it is worth putting together a coherent set in which matching yerba mate accessories play the leading role. Stainless steel cups go best with bombillas made of the same material, which guarantees full resistance to oxidation and a perfect seal. A mateista's professional kit is completed by straw-cleaning brushes and thermoses, which together with a steel matero form a reliable duo for long yerba sessions. A well-matched set of tools not only makes drinking more comfortable, but also makes preparing yerba simpler and more satisfying.
