Double and Single Distillation
The appellation of AOC calvados authorizes double distillation for all calvados but it is required for the AOC calvados Pays d’Auge.
- Double distillation is carried out in a traditional alembic pot still, called either "l'alambic à repasse" or "charentais".
- Single continuous distillation in a column still.
The usual arguments for and against the two processes are that the former process gives the spirit complexity and renders it suitable for longer aging whilst the latter process gives the calvados a fresh and clean apple flavour but with less complexity. In fact there is a growing belief that a well operated column still can produce as complex and "age-able" Calvados as Double Distillation.

Famous quotes containing the words double, single and/or distillation:
“In a symbol there is concealment and yet revelation: here therefore, by silence and by speech acting together, comes a double significance.... In the symbol proper, what we can call a symbol, there is ever, more or less distinctly and directly, some embodiment and revelation of the Infinite; the Infinite is made to blend itself with the Finite, to stand visible, and as it were, attainable there. By symbols, accordingly, is man guided and commanded, made happy, made wretched.”
—Thomas Carlyle (1795–1881)
“You behold a range of exhausted volcanoes. Not a flame flickers on a single pallid crest.”
—Benjamin Disraeli (1804–1881)
“In this century the writer has carried on a conversation with madness. We might almost say of the twentieth-century writer that he aspires to madness. Some have made it, of course, and they hold special places in our regard. To a writer, madness is a final distillation of self, a final editing down. It’s the drowning out of false voices.”
—Don Delillo (b. 1926)
