Amer Picon is a French bitter-orange aperitif liqueur flavored with dried orange peel, gentian root and cinchona bark.
Orange over gentian and quinine, and the bitterness is the half that is hard to find at the right strength. A sweeter orange bottle needs a bitters added; a bitterer one needs syrup, half a barspoon at a time.
Orange liqueur (triple sec / curaçao)
Amer Picon is an amer: its bitterness comes from gentian and quinine, with dried orange peel over the top. Triple sec and curaçao are plain orange-peel liqueurs — sweet, not bitter, so they leave a drink built on Picon sugary and spineless.
Bigallet China-China
The closest thing on an American shelf — orange peel over cinchona and gentian, the same construction. It swaps measure for measure in a Brooklyn; it is a little sweeter, so a dash of orange bitters restores the edge.
Amaro CioCiaro
An Italian amaro led by bitter orange, so it covers the flavor and lands rounder and sweeter. Use the same measure; it will need a little bitterness put back, or the drink loses the dry bite Picon was carrying.
Torani Amer
Widely stocked in the western US and much the sweetest of the three — candied orange rather than bitter. Expect to add two or three dashes of a gentian or orange bitters and to cut the syrup from the build.
The modern product is much lower in strength than the 19th-century original and has been reformulated over the years, which is why older cocktail recipes calling for it rarely match what’s in the bottle today.
