Short answer: Many Jains avoid coffee; some householders take it with care and limits.

Why it’s discouraged

• It is a stimulant (caffeine) that can agitate the mind and hinder saiyam (self‑restraint).
• During Paryushan/Das‑Lakshan, tea/coffee are usually given up as part of austerities.
• Night rules: those who keep chovihār/tivihār don’t take beverages after sunset.
• Milk coffee adds dairy himsā concerns; many Jains now prefer to avoid dairy.
• Instant coffee often has chicory (a root). Strict Jains avoid root‑based ingredients. Check labels.

If you still choose to have it (for lay Jains, outside vrats)

• Prefer plain black coffee in small quantity.
• Avoid after sunset.
• Avoid chicory blends and flavored syrups (may involve root extracts, honey, or fermentation).
• Prefer plant‑based milk if you avoid dairy himsā.

Tradition notes

• Both Shvetāmbara and Digambara traditions discourage stimulants; household practice varies in strictness.
• During Paryushan/Das‑Lakshan, best is to avoid coffee entirely.
