Glendronach 8yrs old, dumpy bottle, 70% Proof

Hi,

Whilst clearing out one of my Grandma's cupboards I came across an unopned bottle of the above. It is still in its box, has a cork with the foil and swing ticket attached. I have spoken with the distillery and they appear to have no records of it. It is not one of the bottles produced in 1976 though! It has a paper label with a picture of the distillery on it. The distillery think it may date back to 1960's when WM Teacher acquired the business.

Any information would be appreciates.

Regards,

Richard Bastow

Nearly the same, but mine is not an export bottle and is 70% proof.

What does 70 proof work out to in the British system? In the US, that would be 35%.

Under the former Sykes hydrometer system, abandoned by UK for beverage alcohol measurement in 1980 to align with EU metrology, 70 proof was equal to U.S. 80 proof, that is, 40% ABV (Gay Lussac system). Sykes assigned 100 proof to a proven spirit, one mixed with gunpowder that burned (both powder and spirit) when set alight, which occurred most satisfactorily at 57.1% ABV. 175 proof was 100% pure alcohol (200 U.S. proof). Anything over 100 proof Sykes was "overproof", anything under, "underproof". 70 proof was 30 underproof.
