How to Make Amaro at Home: Infusing and Sweetening

A bitter liqueur is an infusion that gets sweetened and watered down, and no still is involved at any stage. Macerate three groups of botanicals in 250 ml of high-proof neutral spirit for two to four weeks: a bittering agent (gentian root, cinchona bark or wormwood), an aromatic group (citrus peel, cardamom, cinnamon, clove), and something with body such as dried figs, prunes or toasted walnuts. Strain, sweeten with simple syrup, then add water until the strength lands in drinking range, roughly 20 to 30 percent. Rest the blend for a month before judging it.

Same maceration, opposite destination. Cocktail bitters stay concentrated and unsweetened so that a dash can season a drink; an amaro is sweetened, cut with water to somewhere between 16 and 35 percent alcohol, and rested for weeks until the parts read as one flavor. The practical differences are quantity and patience. A handful of botanicals in two weeks fills a 100 ml dasher bottle, while a bottle of amaro takes several times the material, a syrup, and a month or more of resting.

Less than the finished taste suggests: 150 to 250 g per litre is the usual home range. Add it as a syrup after straining rather than during the maceration, so the sweetness is judged against the bitterness that actually developed rather than the one that was expected. Caramelizing part of the sugar first darkens the color and brings a burnt-sugar note. Stir in half, wait a day, then decide about the rest, because sugar mutes bitterness slowly and nothing takes it back out.
