"Depending on the date a particular bottle is made, the amount of time that that bottle has had to steep may vary. We make extensive efforts to keep inventory levels stocked for all flavors that sell frequently, and those flavors will then have some time to steep until they are ordered and shipped. However, some E-juice is also made fresh and has thus has only steeped from the "Made On:" date on the bottle.
Because bottles are made on different dates, you may receive bottles of the same flavor that are different colors. This is simply because the darker bottles have had more time to steep. Look at the “Made On:” dates on the label to find which bottle has been steeped the longest, and vape that one first. Or if one is darker than another, vape the darker bottle first."
