use this as your base. steep in hot tap water for 5 minute with cap on and tight, shake well. then air out for two days shaking well with the cap on and tight. every 8 to 12 hours then let rest 24. it's good to go, But the flavor gets better the longer you let it sit. I use this for when i can. sometime I need to change the nic base to get the right levels for Flavor.
