Sober Spirits' bitter is built from genuine Italian bitter aperitif that has had its alcohol extracted in Grasse using perfumery distillation. The distillery dates to 1875 and uses the same precision extraction techniques that isolate fragrance compounds in high-end perfume making. What survives is an intensely botanical flavour profile without any ethanol. The aroma is the first thing that hits: blood orange, gentian root, and juniper, with angelica and a dry herbaceous edge. On the palate it is genuinely bitter in the way a Campari or Aperol is bitter — not a watered-down approximation. At 72 calories per 100ml it is the most calorie-dense of the Sober Spirits range, though still modest. No sugar at all. It is well suited to a Negroni build or a Spritz, where the bitterness can carry the drink properly. Mix with Sober Spirits' own gin for an AF Negroni that actually tastes like a Negroni.
