Those guys who always ask about famous Korean teas, I've compiled a detailed list in the post:

• Green tea – nokcha
• Black tea – hongcha
• Mugwort tea – ssukcha
• Korean pine needle tea – Solipcha
• Chrysanthemum tea – Gukhwacha
• Jujube tea – Daechuja
• Pumpkin tea – Hobakcha
• Plum tea – Maeshilcha
• Magnolia berries tea – Omicha
• Yuzu citrin tea – Yujacha
• Barley tea – Boricha
• Brown rice tea – Hyeonmicha

There are a lot of other teas but these are particularly popular in Korea. 

Thank you!
