Sour ?'s

[Mrs C]

Tried searching sour but didn't find much.
Keep in mind I'm very much the beginner on diy.

What is a good sour additive for fruit flavors?
What % to start with?
How long of a steep is needed assuming it's going into a juice that's ready to vape before the addition?

Sour is usually malic acid 10%. Wizard labs super sour is 40% so much stronger. The warheads type super sour would be tartaric acid.
The standard 10% malic acid like tfa sells can have an effect on mixes starting at 1% and at 6% is like a lemon drop.

If your just wanting better profile of fruit flavors you can just use 1-2% of apple cider vinegar.
