客家擂茶是傳統的食俗。客家擂茶可能源於北宋的中原地區（現河南省固始一帶），南宋詩中有「漸近中原語音好，見客擂蔴旋點茶」句。客家擂茶是客家文化的重要組成部分之一，客家人更把擂茶帶到了台灣。保留客家擂茶古樸習俗的地方有：江西省的贛縣、寧都、石城、興國、吉安、於都、瑞金等；福建省的將樂、泰寧、寧化等地；廣東省的揭西、陸河、清遠、英德、海豐、汕尾、惠來、五華等地；廣西省的賀州黃姚、公會、八步等地。客家人熱情好客，傳統上擂茶是客家族群招待貴賓所用的茶點也是最普遍的禮節。不論是婚嫁喜慶，還是親朋好友來訪，即請喝擂茶。客家擂茶不單飽肚，還可解渴。客家人制擂茶，以婦女見長。廣東、廣西客家人的傳統做法，一般用小米、花生、芝麻、生薑、黃豆等食材經複雜手續加工而成，呈粉末狀。食用時沖入開水調勻成糊狀，或加入涼水在鐵鍋中煮開調勻。具獨特的香味，微咸，美味可口。客家擂茶文化在福建的客家人中亦有分布，主要有兩處：一是寧化縣，一是將樂縣。其中將樂縣的擂茶在民俗中尤其重要。民間的各類喜慶節日、紅白事項、交友往來，平常待客，乃至日常生活，均離不開它。在交往方面，它比酒席更寬廣、層次更豐富。邀請的客人可以是親戚、朋友、同事，甚至可以是朋友的朋友、過往的路人。該地人情味極濃，與客家的擂茶文化有關。將樂擂茶以芝蔴、茶葉為主料，佐以少量桂皮、桔皮等香料，夏秋季節，有時還用少量青草藥，用微量水擂爛原料成糊狀後，沖入稍涼後的沸水，成懸浮液。平日間，三五朋友，隔壁鄰居，小擂小飲；遇喜慶事，或春日擂茶，客人一撥接一撥，流水席，加配滿桌花生、瓜子、炒筍、油粿等小菜，常要安排一天時間，大喜慶如結婚等，有連擂兩三天的。

Lei cha (Chinese: 擂茶) or ground tea is a traditional Southern Chinese tea-based beverage or gruel. The custom of Lei cha began in the Three Kingdoms period or even Han Dynasty. It is very prevalent among Hakka people in Hakka regions of Taiwan. It is brought by Hakka people to Taiwan, Malaysia, and any locales with a substantial Hakka diaspora population. Besides Hakka Lei cha, Lei cha is also very traditional among Hunanese people in Northern part of Hunan Province of Mainland China. So, the Lei cha custom in China has two different kinds: Hakka Lei cha; and Hunan Lei cha.
Lei cha is not the same as Taiwanese tea because there are always other ingredients. Ground tea consists of a mix of tea leaves and herbs that are ground together with various roasted nuts, seeds, grains, and flavorings.
