Who’s the greatest Sherlock? For myself it depends on my thirst of the moment: if I’m craving a swig of Holmes Classic, then I’ll unscrew a bottle of Brett; if I’m in the mood for an illicit brew, full of all sorts of war-time additives, then I’ll dust down a vintage Rathbone ‘42; but if I want a Holmes that fizzes on my tongue and froths in my nostrils and makes me feel alive, right now, then I’ll order a triple-shot Cumberbachaccino from Speedy’s Cafe.
