Korean Sejak, is a traditional Korean green tea derived from the tender first bud, and second barely opened tea leaves. Jak is short for Jakseol and simply means green tea. Sejak specifically is handpicked in the latter part of April, before undergoing a more uncommon production technique known as jeungcha. Jeung-cha technique is when the tea leaves are immersed in boiling water for just a few seconds before draining and hot wok roasting. Taste wise, there are a lot of subtleties going on; creamy, sweet, nutty, with a light and piny menthol effect.
