Re: Does shisha flavour go "off"
A biscuit tin is not a good way to store moassel. I always use zip locks. Also, i've smoked stuff that was over 10 years old and had great sessions so age is rarely an issue unless you don't store stuff properly. If it does dry out mix in some melomix or a bit of glycerin and everything turns out fine if you pack your bowl well and manage your coals properly.
