About the Affinity

What 'perfect' means here
Bartenders call a drink 'perfect' when the vermouth is split half sweet, half dry. It is shorthand about the build and has nothing to do with quality. Affinity is a perfect Rob Roy under a different name, which tells you roughly what to expect: cereal and light smoke from the Scotch, wine sweetness on one side, a dry herbal snap on the other.
Two dashes of Angostura do more work here than in most Scotch drinks. Whisky and vermouth share a lot of soft, rounded flavors, and without bitters the middle of the drink goes vague and sweetish. Clove and gentian are what give it definition. Three dashes if your blend is a gentle one.
Common questions
Affinity FAQ
Does a peated Islay malt work in this?
It takes the drink over. Smoke sits on top of vermouth instead of blending into it, so a Laphroaig version tastes like two separate drinks in one glass. Blended Scotch is the traditional pour and the safest. For malt character without the bonfire, use an unpeated Speyside.
I only have one vermouth. What have I made?
Sweet alone gives you a Rob Roy. Dry alone gives you a Dry Rob Roy, which is austere and leans on the bitters much harder. Splitting them is the entire point here: sweet brings fruit and body, dry brings acidity and herbs, and between them the whisky's edges come off.
Is it meant to be this whisky-light at 30 ml?
That's the build as written, and it makes a mild drink. Thirty milliliters of Scotch under 44 ml of vermouth sits closer to an aperitif than to a Manhattan. If you want the whisky leading, go 45 ml Scotch with 22 ml of each vermouth and leave the bitters alone.
Cherry or a twist?
A cherry echoes the sweet vermouth and is traditional. A lemon twist does the opposite job, cutting the wine and pushing the drink drier, which suits a lighter blend. Use a proper brandied cherry if you use one; the neon supermarket kind bleeds dye and tastes of very little.
What ingredients are in an Affinity?
A classic Affinity calls for 30 ml (1 oz) Scotch whisky, 22 ml (0.75 oz) Dry vermouth, 22 ml (0.75 oz) Sweet vermouth, 2 dashes Angostura Angostura bitters. That single-serve spec scales cleanly — the recipe above converts it to oz and multiplies it for 2–4 drinks.
How strong is an Affinity?
A standard Affinity is roughly 27% ABV once mixed (before ice melt softens it further). That makes it spirit-forward — closer to a Martini than to a beer, so sip it slowly.
Is an Affinity shaken or stirred?
An Affinity is shaken. About 13 seconds with plenty of ice chills and dilutes it correctly.
