Although calvados can be dated back to Napoleonic times when it was used both as an anaesthetic and antiseptic in Napoleon’s navy, most calvados is relatively modern. However, you can still buy rare calvados which dates from the first half of the twentieth century. Calvados is made from a cidre which is produced from the apple orchards in Normandy. Apples are not generally acidic enough to start the distillation and so most firms also combine a small quantity of an acidic pear known as a Perry Pear. It is for this reason that most young calvados carry a distinctive pear drop aroma but this will start to mellow after 10 or 12 years and provide a richer apple flavour. Calvados distilled before 1960 are considered as very rare and can therefore attract quite high prices.
