Between roughly 12:30 and 14:30 — sacredly on Sundays — Madrid stops for the vermút: sweet red vermouth drawn from the tap (de grifo), over ice with an orange slice, cut to taste with a hiss of soda from the siphon. It is an appetite-opener, not a session; two rounds and you move to lunch.
What lands beside the glass matters as much: olives stuffed with anchovy, a gilda on a stick, banderillas, tinned cockles or mussels lifted straight from the lata. Ordering conservas with vermouth is not a compromise — it is the highest form of the ritual.
Madrid keeps an unbroken line of tabernas over a century old: carved wooden fronts painted oxblood red, zinc counters with a water channel, tiled walls advertising vinos finos, and barrels that once held the house vermouth. La Latina, Sol and Lavapiés hold the densest constellation.
Treat the room as the attraction and order simply: vermút de grifo, a caña, a half ración from the short list. The houses that survived a hundred years did it by refusing to complicate — reward that.
Say "un vermút de grifo" and you will be understood everywhere; add "con sifón" for the soda. Expect €2.50–4 standing at the counter — terrace seating adds a euro and subtracts the theatre. In the old code, the counter is where things happen.
Vermouth here is almost always red and gently sweet, bittered with botanicals; if you want it drier, ask for blanco. Nobody will hand you a wine list of vermouths — the house pour IS the house.
The canonical route: El Rastro flea market from 10:00, then let the crowd wash you uphill into La Latina at noon. Work the tabernas around the Cava Baja and Plaza de la Cebada one vermút at a time, claim a terrace scrap on Plaza de la Paja, and land at a lunch table by 14:30.
Sleeping in La Latina, Sol or Lavapiés puts the whole rite within ten walked minutes of your bed — which matters, because the vermouth hour has a way of becoming the whole afternoon.
