The guampa is the traditional mate vessel of Paraguay, carved from the horn of a bull or cow rather than a plant gourd. Unlike calabash or wood, a guampa is used exclusively for tereré — the cold version of mate popular in Paraguay and parts of Argentina — since hot water can crack the horn material.
Why Choose a Guampa
A guampa is as much a cultural symbol as it is a drinking vessel, deeply tied to Paraguayan tradition and the social ritual of sharing tereré with friends on a hot day. Its naturally curved, tapered shape is part of its charm — no two are exactly alike, since each comes from a real animal horn. Like calabash, it needs to be cured before first use to prevent an unwanted taste.
Things to Consider
A guampa is strictly for cold drinks — pouring hot water into one can cause it to crack, so it’s not a substitute for a traditional hot mate gourd. Because it’s made from animal horn, some drinkers may have ethical or personal preferences against it; synthetic versions made from stainless steel or other materials that mimic the guampa’s shape are also available for those who prefer an alternative.
Care and Maintenance
Rinse with cold water after each use and let it dry completely. Avoid hot water or sudden temperature changes at all costs, since this is the material’s main weakness. With proper care, a guampa can last for many years and develops a smooth, polished patina over time.
