Yerba Mate for Catering and Event Companies – A Bar Without a Barista

Everyone has seen a waiter with a tray of coffee. A waiter with a tray of tereré, in glass cups with ice and lime, is remembered for much longer. Event and catering companies are increasingly looking for something to set their bar apart from the tenth espresso stand in a row at a trade fair or wedding, and yerba mate happens to be better suited to that than most menu planners would expect.

Why yerba mate even comes up in conversations with caterers

The answer isn’t surprising, but it’s worth stating plainly: the cost per serving is low, preparation doesn’t require a barista course, and the drink has something that coffee and iced tea don’t, namely a story to tell guests. Paraguayan holly brewed in a matero, with a bombilla, is a topic in itself – people ask, take photos, want to know what they’re drinking. For an event organiser, it’s a free source of entertainment at the bar.

The second reason is more practical. Yerba mate can be served hot or cold from the same raw material, without buying a separate product line. In summer, tereré with ice and citrus; in winter, a classic infusion in a thermos – one stock, two serving formats.

The economics of servings – what a serving for 100 people really costs

Here the numbers do a better job than any marketing. The 1 kg Yerba De Brasil doypack is excellent value. The classic brewing ratio is about 1/4 of the matero’s capacity per person, which in practice means 40–50 g of dried leaves for one generous serving with several top-ups of water – because that is the difference from coffee that’s worth pointing out to the customer: one portion of leaves doesn’t end after a single cup. The leaves can be infused again and again, until the brew becomes “lavado”, i.e. flat in taste.

So one kilogram realistically yields anywhere from a dozen to well over twenty full servings, depending on how many rounds of water the guest tops up. At the price of a single kilogram, the cost of the raw product per person drops below the price of one vending-machine coffee in office catering, and with larger wholesale orders – which are worth asking about directly – it goes even lower.

Formats that work well for jobs

Not every event is the same. A conference in a hall requires something different than an outdoor wedding, and a tasting stand at a trade fair follows yet other rules. Three variants that are in practice easiest to implement without extra equipment:

• Cold tereré in pitchers – poured with cold water, with ice, lime and mint. Perfect for outdoor summer events, since it requires no heating at the stand, only ice coolers.
• Classic infusion from a thermos – water at 70–80°C prepared beforehand in the catering kitchen and transported in thermoses. The guest receives a matero or a cup, it’s topped up from the thermos, and the bombilla does the rest.
• Self-service station – several thermoses, disposable cups or borrowed matero cups, a note with instructions on “how to drink”. Works well at large corporate events where there’s no dedicated staff member serving just one drink.

Logistics – service without a barista and without an espresso machine

This is the argument that appeals most to catering business owners counting labor costs. Espresso at an event requires a person at the machine for the entire duration of the event, water service, pressure cleaning, and power of the right output. Yerba mate prepared in advance in thermoses requires none of that – only topping up.

The TERREMOS PRO MAX thermos has a spring filter and a straw built into its construction, and is made of BPA-free stainless steel – it’s equipment that one staff member can carry between tables without risk of spilling or burns, unlike an uninsulated jug of hot water. For a catering business handling several events a month, it’s an investment that pays off quickly, since there’s no need to rent or service any equipment.

Classic dried leaves or something with character – what to choose for your first job

Companies that are only just testing yerba mate in their offering usually ask whether it’s better to go straight for a flavoured version, with fruit or herbs. The answer depends on the type of event. A classic, plain dried leaf like Yerba De Brasil – 100% leaves of the Paraguayan holly, dried leaves from the Rio Grande do Sul region, without smoke or tar substances in the drying process – works well where authenticity of the ritual matters most: industry conferences, premium events, trade fairs with an audience genuinely interested in the product itself.

At weddings and mass events, the flavoured version tends to win more often, because a guest seeing a matero and bombilla for the first time in their life is more likely to reach for something that resembles a fruity drink than for a plain, slightly bitter infusion. A good solution here is an earlier tasting session with a few variants, then choosing one or two flavors for the menu for the whole season.

A brand some guests already know

This is an extra argument rarely considered when planning a catering bar, yet one that matters at an event involving media or influencers. Some guests will recognise the brand from the ad before even trying it – that makes conversation at the bar easier and gives the organiser something more than an unknown, anonymous dried leaf in a plastic bag.

Certificates the purchasing department asks about

In catering and event contracts, a corporate client’s purchasing department usually asks about documentation, not marketing. The leaf comes from Brazil, packaging takes place in Europe, and the whole line holds certification from the Swiss company OROTAL Commodities Trading SA, plus HACCP and KIWA. On top of that, there are certificates of analysis from independent laboratories – IWNIRZ (Institute of Natural Fibres and Medicinal Plants, authenticity testing by chromatography), J.S. Hamilton (compliance with the reference standard) and GBA Polska (heavy metals, pesticides, PAHs), as well as ECOCERT and Organic Brasil certificates. On the Polish market there’s also the Quality Certificate from the National Medicines Institute. These documents can be sent along with the wholesale offer – in B2B conversations they often decide things faster than a flavour sample alone.

Three products for the first order

No need to overdo the range at the start. These three items are enough to handle a first test event and see how guests react, before deciding on a permanent partnership.

Check out the product: Yerba De Brasil – Doypack 1 kg

The largest pack in the shop’s regular range. Classic dried leaves with no additives, a production tradition dating back to 1951, and a sensible basis for calculating the cost of a single event before discussing wholesale.

Check out the product: Yerba De Brasil – Doypack 0.5 kg

A smaller pack for testing before the season, for a tasting with your service team, or for a small intimate event where a full kilogram isn’t needed.

Check out the product: TERREMOS PRO MAX + Doypack FREE!

Comes with an extra doypack free. BPA-free stainless steel, a spring filter and a straw included – one set of equipment that handles service without plugging anything into the mains, so it also works for outdoor events with no access to sockets.

What working with Yerbador looks like

Requests for quotation are sent by e-mail to the team handling B2B enquiries. In reply you will normally receive a price list for orders above a certain quantity threshold, the availability of classic and fruit flavors, and information about lead times – for events with a fixed date it is worth asking well in advance, so that the order arrives before the event rather than on the day it starts. A smaller test sample before placing a larger order is also possible – this is standard practice when working with a new supplier for the first time.

Questions catering companies ask us

Do I need a trained bartender to serve yerba mate?

No. The infusion can be prepared in advance in the kitchen and transported in thermoses, and at the stand you only need to top up the guest’s matero or cup with water. The only skill that helps is calmly explaining to the guest how to hold the bombilla – and usually one sentence is enough.

How many servings do you get from one kilogram of dried leaves?

Roughly a dozen to over twenty full servings, since one portion of leaves can withstand several water refills before the flavour goes flat. The exact number depends on how strong the guests like their infusion and how many rounds of water they add.

Can yerba mate be served cold at an outdoor summer event?

Yes, that’s tereré – pouring cold water, usually with ice, lime and mint. It’s the same dried leaves as the hot version, so the caterer doesn’t need to buy a separate product for the summer season.

Can I test the product before ordering a larger quantity?

Yes, the smaller 0.5 kg pack is enough for a tasting with the service team or a small test event before deciding on a regular wholesale order.

Will I receive documentation for the purchasing department with my order?

Yes – OROTAL, HACCP and KIWA certificates, as well as analysis certificates from independent laboratories (IWNIRZ, J.S. Hamilton, GBA Polska), can be provided along with the offer; Ewelina sends them after the first email contact.

A shared matero passed between guests has something no coffee machine can replicate – a ritual that makes people pause and talk instead of grabbing a cup and walking away. For an events company, that’s exactly the kind of detail guests remember and keep talking about a week after the party.
