wonder any1 can explain to me..is there anything (in the menthol) e-liquids that is perishable?..i have just acquired a 500ml bottle of PG menthol @ 48mg strength..does the e-liquids has a expiry date(1 yr or more) on it? or does the e-liquids matured with aged?..presently i store all my e-liquids in the fridge rather than a cool place in the dark,in doing so can prolong my e-liquid's life? ..with my (1/3)menthol @ 48mg diluted with (2/3)VG base to produce my favorite <18mg menthol "cloud of smoke" vape & can last me at least 2 yrs..hope to get answers to my dilemma..thanks in advance..regards mafig
