I have perhaps an ounce of the original McC Anniversary Blend left. It was Tinned in 2002 and I opened My last tin early this year. This is a VERY light Lat blend yet it is still very present in the blend. My next two tins are from the 05 tinning and I am not at all worried about it. After that I have several of the 2010 tins. I am quite sure I will enjoy those too.
