If only there was someone on this forum that might have the answers...
So, for the record, we never stopped producing concentrates as a consious decision, it kind of just seemed that the demand fizzled out. If there's a demand for it, we'll make some, simple as that.
I know some e-liquid companies are hesitant to release concentrate versions of their products as they feel it will reduce demand for their main e-liquids, but as someone that has purchased vast amounts of both DIY and mainstream products in my time, it's clear that concentrates and premade products are 2 completely seperate entities, with completely seperate markets and uses.
To a big extent you have to trust the customer and realise that they know what they want IMHO, rather than forcefeeding them what you want them to want.
Finally, I have bad and good news for you
@mick brown
Bad: Mint Royale can be no more. One of the ingredients has been discontinued. #SadTimes
Good: I don't have the time or inclination to reformulate it, so I'll send you the recipe if you want. I'm sure you'll be able to hunt down small volumes of the discontued ingredient easily enough. I've seen it for sale in a few places, Just not in the volumes we'd need commercially
