SafAle S-04 substitute: what to use instead
SafAle S-04 (Fermentis)If you cannot get SafAle S-04, this is the closest replacement and what changes.
Close, with a caveat. White Labs WLP002 English Ale or Wyeast 1968 London ESB is the nearest substitute for SafAle S-04, but it will not match on every point.

Notes
S-04 is a Whitbread-derived English strain; WLP002 and Wyeast 1968 are the usual liquid substitutes because all three are high-flocculating English ale yeasts.
They match on behaviour, high flocculation and a fast, warm English ferment, but not on flavour: WLP002 and 1968 are noticeably more estery and finish higher than S-04. Treat them as the same job, not the same beer, and expect a fruitier, slightly sweeter result.
