Go before 13:30 or after 20:00 on weekdays
Bodegas Castañeda pulls the tourist crowd at lunchtime — the calicasas queue at the bar is real by 14:00. Come before 13:30 and you get bar staff with attention to spare. The same logic applies after dinner: from 20:00 onwards the crowd at Castañeda and Los Manueles shifts toward local regulars. The tapas tend to be more generous at those hours too.
