Heat deteriorates nicotine..supposedly....however some time ago some random left a bottle in his car for about a month in the dead of summer and he could.d not personally detect any changes.
See this confuses me steeping is CLEARLY important but cap on... cap off... take the cap of every once in a while... sunlight.... dark cabinet... Is it all personal preference?
Crikey whit77 what a difference, that's incredible and after just a couple of hours.
I steep in a dark cool place but may try this myself with a bottle or two.
