The printing on the box was clear. Best before 27 Dec 2013. You have been taught not to consume food pass its expiry date. It will not be safe and may be toxic if you eat or drink such products.
There are food where it will appreciate in terms of aroma and taste with time in storage. Wine, preserved meats and even cheese and chocolate. Certain tea like roast oolong, liu bao, black tea and pu erh are highly sought after if these tea are stored properly with age.
You will notice that this tea inside the tin are rolled tea. This may suggest that it may a few infusions before the full flavor to come through as it will take a few infusions to unfurl the tea leaves. Likewise, if you are brewing pu erh leaves in small chunks, it may take a few rounds before the taste and aroma is more complete.
This old 100g tinned Ti Kuan Yin by Sea Dyke is a delightful proposition. There is a gentle oily and long slightly sweet aftertaste. I am happy. A good tea need not be an expensive tea.
