How much menthol to add to Mahalo Oahu?

[bmwjen]

I'm seriously loving this juice! So, just like all juices that I love, I've gotta add some menthol to it. I'm wondering just how much menthol (ml) to add to a 30ml bottle. I'm thinking 5%, so maybe 1.5ml?

Menthol lovers help me out here so that I don't ruin an ounce of my lovely MO.

I don't know about what percentage of Menthol to use, but you might want to mix a much smaller batch in a smaller bottle (like 3 or 6 ml). That way if you mess it up, you haven't wrecked your whole 1 oz bottle.

Good luck!
