Chaive Coffee Roasting Lab is a coffee shop in Seoul that roasts its own beans and serves cafe lattes. It offers a choice of an Ethiopian blend and natural or washed beans, with a latte made using Natural Plan milk as the signature drink. The shop uses a La Marzocco GS3 machine and an SP2 grinder, and serves coffee in spring water and Italian Ancap cups. The beans keep their natural milk-chocolate sweetness even as the coffee cools.
