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 whether there are other additive polynomials except these linear combinations. The answer is that these are the only ones. One can check that if "P"("x") and "M"("x") are additive polynomials, then so are "P"("x") + "M"("x") and "P"("M"("x")). These imply that the additive polynomials form a ring under polynomial addition and composition. This ring is denoted This ring is not commutative unless "k" equals the field formula_8 (see modular arithmetic). Indeed, consider the additive polynomials "ax" and "x" for a coefficient "a" in "k". For them to commute under composition, we must have or "a" − "a" = 0. This
