紧压茶是为了长途运输和长时间保存方便，将茶压缩干燥，压成方砖状或块状，为了防止途中变质，一般紧压茶都是用红茶或黑茶制作。

紧压茶喝时需用水煮，时间较长，因此茶汤中鞣酸含量高，非常有利消化，但也促使人产生饥饿感，所以喝时一般要加入有营养的物质。蒙古人习惯加奶，叫奶茶，藏族人习惯加酥油，为酥油茶。

Tea bricks (simplified Chinese:砖茶; traditional Chinese:磚茶; pinyin:zhuān chá) or compressed tea (simplified Chinese:紧压茶; traditional Chinese:緊壓茶; pinyin:jǐnyā chá) are blocks of whole or finely ground black tea, green tea, or post-fermented tea leaves that have been packed in molds and pressed into block form. This was the most commonly produced and used form of tea in ancient China prior to the Ming Dynasty. Although tea bricks are less commonly produced in modern times, many post-fermented teas, such as pu-erh, are still commonly found in bricks, discs, and other pressed forms. Tea bricks can be made into beverages like tea or eaten as food, and were also used in the past as a form of currency.
