Johnnie Walker Red Label Antique Bottling

[Scranmerchant]

Just wondering, I recently inherited a JW red label. It looks pretty much identical to this:

Is there a sure fire way to know when it was bottled? Any clues? Level’s still pretty high but has been a slight evaporation.

Cheers!

There are some clues when trying to figure out when a bottle was actually bottled.

In the UK up until 1980 standard size bottles were 26 2/3 flozs, they then changed to 750ml in 1980.

About 1991/1992 the EEC (or EU as they call it now) changed the standard size from 750ml to 700ml.

Up until January 1st 1980 the UK used the Sikes system of measuring the proof strength of spirits, the Sikes system had been used in Britain for 162 years.

Like other EEC countries they replaced the Sikes system with the OIML system (International Organisation of Legal Metrology). The OIML system measures alcoholic strength as a Percentage of Alcohol by Volume (%ABV) at a temperature of 20 degrees C.
