1971 The Macallan Anniversary Malt 25 Year Old Single Malt Scotch Whisky (700ml)
If you're after more detail on the provenance of this bottling, this from the Macallan Marketing department:
"We stopped referring to our 25 years old as the Anniversary Malt in 2004 but the wooden Burgundy box was only in place for less than 2 years so I would suggest that your bottle was released in 2002/3. The year of distillation was removed a year or two before that as this conveyed that all the whisky contained therein was distilled in that year, whereas this was not always the case. There is frequently older whisky contained in the vatting... the bottle will contain whisky distilled in 1978 or before." 43% Alc./Vol.
