⛩When we talk about oud there is one important country we need to mention, Japan. In the 17 century Japanese created a theory to identify ouds. This theory is called “六国五味” which at that time Japanese separated the oud roughly to 6 countries and 5 smell. Ofcause they already realized that the oud from same area can be different smell and oud from different area can be same smell. The 5 smells are,
⛩spicy (like clove)
⛩Sweet (like honey)
⛩Salty(like air near the sea)
⛩Sour( like plum smell...
