100° proof – about 57.15% alcohol by volume – is an iconic bottling strength. Not only was it popular in decades past, but the extra strength over standard bottlings has helped preserve the flavour and character of old and rare bottles. 

One of the most common problems with older bottlings of single malt from the 1970s and earlier decades is that their lower bottling strengths mean that they often don't 'travel' too well in their bottle during the intervening decades. Often showing signs of tiredness or 'old bottle effect'. That's why the old higher strength bottlings at 100 proof (57.1%) are so popular these days. These bottlings represent the closest we can get to how these spectacular whiskies tasted when freshly bottled all those years ago.

Join Whisky Show Old & Rare co-organiser Angus MacRaild for a delve into some scarce and incredible whiskies all bottled prior to the 1980s at 100° proof.
