How to brew tea in Rust
Tea is brewed at a Mixing Table or Cooking Workbench using berries you've farmed. Every tea has three tiers — basic, advanced and pure — that scale by how many same-colour berries you put in. Pure-tier teas are the only ones worth using in a serious farm.
Tea types and their berries
- Healing tea — Red berries. Heals you over time. Mostly outclassed by Max Health tea.
- Max Health tea — 3× Red, 1× Yellow. Buffs max HP — essential before any fight or raid.
- Ore tea — 2× Yellow, 2× Blue. Boosts ore yield. The grinder's tea.
- Wood tea — 2× Red, 2× Blue. Boosts wood yield. Pair with chainsaw runs.
- Scrap tea — Yellow + White. Boosts scrap from recycling and barrels.
Pure tier vs basic tier
A basic tea takes 4 berries (e.g. 2× yellow + 2× blue for ore tea). An advanced tea combines 4 basics into 1 advanced — so 16 berries' worth. A pure tea combines 4 advanced into 1 pure — so 64 berries total. Pure-tier buffs are dramatically stronger and the standard for serious farming; basic-only is a wipe-day stopgap. The calculator above shows how many of each tier you can make from your current berry stockpile.
How long do tea buffs last?
Most farming buffs (Ore, Wood, Anti-Rad) last 30 minutes at every tier. Pure Scrap Tea is the longest at 60 minutes. Max Health Tea lasts 20 minutes. Healing Tea is consumable-style (instant heal at consume + heal-over-time). Plan to drink each tea right before the activity, not in advance.
Stacking rules
You can stack one tea per type at the same time — drink ore tea, max-health tea and wood tea simultaneously and all three buffs apply. You cannot stack two of the same type at different tiers. Drinking a pure tea after a basic immediately replaces the basic.
What to brew first on a wipe
Most farmers prioritise max-health tea first (combat survivability), then pure ore tea for sulfur runs. If you're playing a building/farming role, brew pure scrap tea before recycler trips. Run the numbers through the Yield Calculator to see exactly how much extra you'll net per session.
