STORING TEA
Ideally, it would be best to keep tea in a small airtight container for everyday use and then keep larger quantities well sealed and tucked away. Airtight tea tins and canisters are an effective way to store tea, they will often have a double lid moisture seal and the material is non porous and impervious to light. If kept properly, black tea will keep for up to 2 years whilst green or white tea will remain fresh for up to 12 months.
It is not advisable to keep tea in a refrigerator or freezer as opening and closing the door causes rapid changes in humidity. Also, avoid storage near areas of steam such as dishwashers or steaming kettles. Moisture seeping can cause tea to mould and decay. To retain great flavour for as long as possible store at a constant temperature in an airtight container and away from light, heat, moisture and strong odours.
If exposed to sunlight, over time tea leaves will lose their colour as well as their refined flavour. Strong odours can permeate tea very easily so avoid storing near spices or aromatic items. It also makes sense to keep delicate teas away from scented or flavoured teas. Also, be sure to air out any container that has been used for other foodstuffs or another tea type before use.
