General coffee community vs espresso-focused practice

r/Coffee is a general coffee discussion room. r/espresso concentrates on espresso brewing—machines, technique and gear culture.

In our directory Coffee is about 2.5M members (rank #447); espresso resolved at about 0.65M without a Top-1000 rank in the same snapshot. Activity samples show espresso busier (~104 posts/day vs ~28), typical of a specialized troubleshooting/gear room.

Rule titles: Coffee emphasizes coffee focus, limits low-effort questions, bans elitist nonsense and affiliate shilling. espresso tells people to read the wiki first, use flair, bans boxed-equipment flex photos and purchase screenshots, and keeps posts relevant to espresso.

  • Ask general bean/brew/cafe questions on r/Coffee.
  • Take machine dial-in, espresso gear and technique questions to r/espresso (after the wiki).
  • Neither sits in the live Top 100 cut—SubMouse links go through the info tool when no full /r/ page exists.

Where this comparison comes from

Coffee members/rank from the SFW directory; espresso members via SubMouse resolve of public directory/archive data. Short rule titles and activity samples SubMouse collected. Short titles only.

Members and public descriptions come from SubMouse's safe-for-work directory (as of 2026-11-02 UTC); 7-day growth measured from 2026-10-26. Posts/day and post-type mixes appear when we have an activity sample. Rule lines are short titles, not the full sidebar. Directory rank is listing order — communities outside the current Top 100 open in the info tool instead of a full community page.
