One can only assume that the link between the Loch Ness monster and 70º proof whisky is that the consumption of the one makes you think you have seen the other.
However this wee decanter would not do the biz as the volume it contained (and if you are employed by customs and excise please note the use of the past tense here) was barely enough to inebriate a haggis.
