Guides for adding terpenes to drinks

Hello all,

I own a dispensary and I am looking to create a beverage to sell. I am starting work on proof-of-concepts.

I've been attempting to determine how to properly dose drinks with terpene concentrates. Unfortunately, unlike CBD or THC, there seems to be a lot of discrepancy on how to properly dose them. Some guides call for a few eye drops per liter, some call for 1-5% volume by weight, etc.

Does anyone here know how to dose drinks in this way?
