Canned tea is a relatively recent method of marketing tea which has been sold traditionally as leaf tea and also, for the last 100 years, in tea bag form. It utilises the canning process to produce a ready made drink. Perceived advantages includes ease of use (minimal or no preparation time) and the possibility of additives (such as flavours or sugar); the disadvantages are the cost of shipment (and therefore the price of the product) and a lack of freshness.[1]
