A tea infuser, a device designed to contain loose tea leaves during the brewing process, facilitates the creation of a beverage without the need for tea bags. Its primary function is to allow water to circulate through the leaves, extracting flavor, while preventing the leaves from escaping into the final cup. Models vary in shape and material, encompassing mesh balls, baskets, and specialized tongs, each serving the same fundamental purpose: controlled tea steeping.
The benefit of utilizing such a device lies in its ability to unlock the nuanced flavors inherent in loose leaf tea, often surpassing the quality achieved with pre-packaged bags. Furthermore, it promotes environmental sustainability by reducing reliance on disposable tea bags, many of which contain plastic. Its history, though not exhaustively documented, traces back to the increased availability and appreciation of loose leaf tea, necessitating a mechanism for convenient preparation.
