Rust Warming Tea

By Frozen · checked in-game on the live patch · Updated 3 July 2026

// Basic: red + yellow berries · Advanced: 4× Basic Warming Teas · Pure: 4× Advanced Warming Teas

Warming Tea is the cold-biome survival consumable in Rust. With Pure Warming Tea active, you gain a temperature buff and a hydration boost that protects against freezing damage in snow biomes — letting you stay at Arctic Research Base, Train Yard in winter conditions, or ice lakes without dragging a campfire. Like every Rust tea, it follows the standard tier progression: 4 berries make 1 Basic, 4 Basics make 1 Advanced, 4 Advanced make 1 Pure. Specific temperature numbers vary by patch — verify in-game against your current map biome.

Recipe & tiers

Tier	Effect	Duration	Berries
Basic	Cold-biome heat buff (basic)	20 min	Red + yellow berries (verify pattern in-game)
Advanced	Cold-biome heat buff (medium)	20 min	4× Basic Warming Teas combined
Pure	Cold-biome heat buff (strongest)	20 min	4× Advanced Warming Teas combined

Brew at a Mixing Table or Cooking Workbench. The order of berries in the slots matters — check the Berry & Tea Reference if unsure. The Tea Brewery Calculator tells you how many of each tier you can brew from your current berry stockpile.

When to use it

Snow biome runs: Arctic monument, Train Yard in winter, ice lake roams. Drink before entering — Pure tea lasts a full hour, longer than any other tea in the game.

What it stacks with

Snow jacket / coffee can helmet — Clothing insulation stacks with the temperature buff
Burlap clothing in mid-cold areas — Burlap is enough at -5°C with Pure tea active
Max Health Tea — Run both for cold-biome combat readiness

What it doesn't stack with

Cooling Tea (the opposite tea — drinking one replaces the other).
Another Warming Tea — replaces, doesn't double up.

Tips from the wipe meta

Pair Pure Warming Tea with a snow jacket and you can stay in cold biomes for sustained periods without an external heat source.
Plan brewing in advance — Pure tier needs 16 Basic Teas (~64 berries), so a dedicated red/yellow plot helps if you play a lot of cold-biome content.
Useful in winter wipe events when cold zones expand into normally-temperate areas.

Common mistakes

Drinking in temperate biomes — no benefit, you'll waste a 60-minute buff.
Using it as a substitute for a snow jacket — the tea alone won't save you in extreme cold.
