Rosso vermouth is a sweetened, aromatised fortified wine flavoured with Artemisia (wormwood) and carrying at least 130 grams of sugar per litre.
High sweetness carries a herbal, wormwood-led bitterness, with a medium body and pronounced aromatic depth from the botanicals.
Poured in anything from a small seasoning accent to a large measure, it stirs into a build to add sweetness, herbal aroma and colour; as a base or major component it defines the drink, while a small accent tolerates another sweet aromatised wine standing in.
Another sweet, wine-strength aromatised wine carrying wormwood aroma is the honest swap; a drier fortified aromatised wine can be rebalanced with sugar syrup, but a plain sweet wine or non-wormwood liqueur will not reproduce the defining Artemisia character.
Bitter aromatised wine
Bitter aromatised wine is defined by a characteristic bitter flavour, whereas sweet vermouth is defined by Artemisia (wormwood) flavouring and, in the sweet designation, high sugar. Both are fortified aromatised wines but they are distinct legal categories.
Both are wormwood-flavoured aromatised wines, but dry vermouth holds under 50 g/L of sugar and is usually pale, while rosso vermouth carries 130 g/L or more and is usually red.
Built from a base wine that is fortified with added alcohol and aromatised with botanicals including obligatory wormwood species, it is sweetened to its high-sugar designation; the base wine is usually white, with the characteristic red-brown colour typically supplied by added caramel rather than the wine itself.
Being wine-based, it oxidises once opened; refrigerate and use within a few weeks before its fresh aromatic character fades.
Vermouth in its modern commercial form originated in Turin, in the Piedmont region of Italy, in the late 18th century.
