I'm thinking of using coriander essential oil instead of crushed coriander seed for my Belgian Witbier. The problem is to find the sweet ratio. What I want is just subtle note of coriander aroma but the essential oil definitely super condensed.
Replicating cold infusion environment, I put a single drop of the oil into varying amount of cold water (room temperature =24c). Below is the result of my sensory experiment. Assuming that one drop of essential oil is 0.05 ml. Aroma and Flavor points are in a range of 0 to 9.

I found 1 drop for 1L water is what I desired. Which means, I need only 12 drops of essential oil (0.6ml) for my 120L batch of beer. This oil is monster!
