Fortified wine because he was inspired by a German wine flavoured with wormwood, an herb most famously used in distilling absinthe. However, wine flavoured with wormwood goes back to ancient Rome. The modern German word "Wermut" ("Wermuth" in the spelling of Carpano's time) means both "wormwood" and "vermouth". The herbs were originally used to mask raw flavours of cheaper wines, imparting a slightly medicinal "tonic" flavor. Vins doux naturels are lightly fortified wines typically made from white Muscat grapes or red Grenache grapes in the south of France. The production of vins doux naturels was perfected by Arnaud de Villeneuve at the
Additive polynomial "p" is prime, for all "n" = 1, ..., "p"−1 the binomial coefficient formula_3 is divisible by "p", which implies that as polynomials in "a" and "b". Similarly all the polynomials of the form are additive, where "n" is a non-negative integer. The definition makes sense even if "k" is a field of characteristic zero, but in this case the only additive polynomials are those of the form "ax" for some "a" in "k". It is quite easy to prove that any linear combination of polynomials formula_6 with coefficients in "k" is also an additive polynomial. An interesting question is
