% wise.
The easiest for me is to count in drops.
1 ml of
juice = 20 drops.
10 ml of
juice is 200 drops.
5% of 200 drops = 10 drops.
So if you start with 10 ml, you can add 10 drops.
Start easy, don't mix too many different flavors.
Maybe 2 flavors or 3 max.
Think of flavors that you think might taste good together.
Good luck, and don't forget to steep the juice.
After I made the juice I put it in a little bowl with hot water, let it cool down while sitting in the water.
Shake it and put it in a dark place.
I shake it everyday, and want to let it steep for about 3 weeks.
