At the beginning of the pandemic, the advice about hand sanitisers based on ethyl alcohol was an alcohol content as high as 85%. But now we have settled down and 70% or even 60% are considered enough. This suggests that lacking hand sanitiser you could in an emergency use Woods Old Navy Rum, 57% ABV.
So the legend that, after the battle of Trafalgar Nelson’s body was brought home preserved in rum, or possibly brandy, is more believable than I always imagined. But according to Wikipedia the Admiralty records refer just, somewhat coyly, to “Refined Spirits”. So we cannot ever know exactly what was used.
