Rule #6:
THE ART OF POURING
When pouring a drink for an equal or a friend, use your right hand to pour and keep your left hand on your forearm or elbow. This comes from the days when people wore a “hanbok” (a traditional Korean garment)- people would use their left hand to prevent the baggy sleeves from touching the food.

Using two hands to offer and accept items is a sign of respect, so when pouring or receiving a drink from an elder, hold the glass or bottle with both hands.
