It's likely the original Martinez was based on Dutch jenever rather than English old tom or dry gin and O. Byron's 1884 The Modern Bartender suggests it would also have had a couple of dashes of both Angostura bitters and orange curaçao. The proportions of vermouth used reflect the sales of French and Italian vermouths in America at the time.
Unknown but this 15:1 gin to vermouth Martini was said to be Ernest Hemingway's favourite formula and is named after British Field Marshall Bernard Montgomery, who it is said, liked the gin in his Martini to outnumber the vermouth in roughly the same ratio as he liked to outnumber his opponents in battle. Nicknamed ‘Monty’, Field Marshal Bernard Law Montgomery (1887-1976) fought and was seriously wounded in the First World War and was one of the most notorious British commanders in the Second World War. He commanded allied troops at the Battle of El Alamein and was a key planner of the Normandy D-Day invasion. On 4 May 1945 he took the German surrender at Luneburg Heath in northern Germany.
Created in 2006 by yours truly (Simon Difford) at the Cabinet Room, London, England. I updated this recipe in 2013. Older? Yes. Wiser? Perhaps. Drier palate? Definitely. Hence, seven years after creating this drink I reduced the elderflower liqueur from 3/4 shot to 1/2 shot and I also reduced the vermouth from 1/2 to a 1 /4.
Created in 2008 by yours truly (Simon Difford) at the Cabinet Room, London, England. James Bond named his favourite style of Martini after the beautiful Russian agent Vesper Lynd. This version is 'Reversed' due to the dramatically increased ratio of Lillet Blanc. Fittingly my drink mixes east and west ingredients with the introduction of Becherovka. And where there is Becherovka there should be tonic water. (See Be-ton).
