Wet yerba overnight
This can cause smell or mould, especially in natural calabash and wooden gourds.
What is a mate gourd?
A mate gourd is the vessel used to prepare and drink yerba mate.
In Spanish, it is usually called a mate. The word can refer to both the drink and the cup itself, depending on context. You may also hear calabaza when people talk about the natural gourd material, because traditional mate cups were often made from dried calabash gourds.
Before mate became something people drank from stainless steel, wood or ceramic cups, it was traditionally prepared in a natural gourd. That is why the gourd is not just a container. It is the centre of the ritual: the yerba is placed inside, the bombilla rests in it, and the drink is prepared from it.
Different gourds create different experiences. Stainless steel feels modern and easy to maintain. Wooden gourds feel warmer and more natural. Natural calabash gourds carry the strongest connection to tradition, but they also need the most care. Ceramic, glass and silicone mate cups also exist, but in this guide we focus on the most common styles people usually choose for everyday mate rituals.

Before first use: curing a natural calabash gourd
A natural calabash gourd is made from a real dried gourd. Before using it regularly, many mate drinkers cure it first.
This first-use step has a cultural and practical purpose. It helps clean loose inner fibres, lets the natural material adjust to moisture, and prepares the gourd for regular mate drinking.
Good to know: Do not use boiling water. Do not scrape aggressively. Let the gourd dry completely after curing. Natural smell, small marks and colour changes are normal with natural calabash.
Daily care for your gourd
The most important rule is simple: do not leave wet yerba sitting inside.
Natural calabash and wooden gourds are organic materials. They can last a long time, but they need airflow and proper drying. Most care problems come from trapped moisture, not from normal use.
What is a bombilla?
A bombilla is the filtered metal straw used to drink yerba mate.
Unlike a regular straw, a bombilla has a filter at the bottom. This allows you to sip the infusion while keeping the yerba leaves inside the gourd.
In Spanish, bombilla is the word commonly used for the mate straw. It usually refers to the metal straw with a filter used in Argentina, Uruguay and other mate-drinking traditions.
In mate culture, the bombilla is not just a tool. Once placed into the yerba, it usually stays in position. You drink through it, return the mate, and the ritual continues from the same gourd and the same bombilla.
How to use a bombilla properly
The bombilla is there to drink, not to mix.
Once the yerba has been shaped and moistened, place the bombilla into the wet side of the gourd. Let it rest in position while drinking. Moving it around too much can disturb the yerba and block the filter.
In a social setting, it almost becomes part of the conversation. As Ariel says, it can feel like your little microphone — while you hold the mate, you enjoy your moment, speak, listen, laugh or simply pause.
Do
- Insert it after the yerba has been shaped and moistened.
- Place it into the wet side of the gourd.
- Let it stay in position while drinking.
- Rinse it after use.
Don’t
- Do not stir the yerba with it.
- Do not move it around too much.
- Do not leave it dirty inside.
- Do not store it wet for long periods.
How to clean and care for your bombilla
Even if the outside looks clean, the inside of the straw can hold residue.
Common care mistakes to avoid
Not drying fully
Drying is the most important care step for natural materials.
Harsh cleaning
Avoid harsh soap, strong chemicals or aggressive scraping on natural gourds.
Stirring the bombilla
The bombilla is not a spoon. Stirring can block the filter and disturb the yerba.
