Cuia is a traditional drinking vessel commonly used in Brazil, particularly in the southern regions. It is typically made from the gourd of the Lagenaria siceraria plant and is often decorated with intricate designs. The cuia is primarily used for serving mate, a popular herbal tea made from the leaves of the Ilex paraguariensis plant. To drink from a cuia, a metal straw called a bomba is used. The preparation of mate involves filling the cuia with dried leaves, adding hot water, and sipping through the bomba. This social ritual is an important part of Brazilian culture, fostering community and connection among friends and family.
