I tend to mix my concentrates as single flavours, then mix recipes from them.
I use DarkArts Forest Fruit at about 5%
Capella Vanilla Custard at 9.5 %
Capella Peanut Butter at 4 %
Then I mix them together.
Forest fruits 75%
Vanilla Custard 15%
Peanut Butter 10%
The main reason I don't mix them to a recipe from the start is because I mix up large amounts of Forest Fruits as a base for a few recipes.
I make smaller amounts of Peanut Butter because the flavour fades a bit over time.
And i make smaller batches of Vanilla Custard because of the 3 week minimum steep time.
Also, if i have a few different flavours ready mixed and steeped, it's a lot easier to make small testers of new recipes.
