Tea bricks are compressed blocks of tea leaves that need to be broken apart before brewing. The process is straightforward once you know the right tools and technique: pry off a portion with a pointed tool, rinse the leaves briefly, then steep them in hot water. The details vary depending on the type of tea brick and the brewing style you choose.
Breaking Apart a Tea Brick
Tea bricks are densely compressed, so you can’t just crumble them with your fingers. The goal is to separate the leaves in chunks without crushing them into dust, which would make your tea bitter and cloudy.
The best tool for the job is a tea pick (sometimes called a tea needle), which looks like a small ice pick. Insert it into the side of the brick at a slight angle, then stab two or three more times nearby at slightly different angles. This loosens a section of leaves, and you can gently pry it apart. Work along the natural layers of the brick rather than trying to chip straight through it. A dedicated puerh knife works too, though many tea drinkers find picks easier for heavily compressed bricks. If you don’t have specialty tools, an oyster knife does the job surprisingly well.
For a single serving, you’re aiming to break off roughly 5 to 8 grams, about a heaping tablespoon of loosened leaf. You don’t need a scale, but one helps if you want consistency. Once you’ve broken off what you need, store the rest of the brick as-is.
Rinsing the Leaves
Before your first real steep, rinse the broken-off leaves with hot water for 5 to 20 seconds, then pour that water out. This step is especially important for compressed teas. The rinse washes away dust and fine particles that accumulate during pressing and storage, and it “wakes up” the leaves by pre-soaking them so they unfurl more evenly during brewing. For aged teas like puerh, rinsing also clears any stale surface flavor, letting the true character of the tea come through. Think of it as a warm-up, not a waste.
Brewing With the Gongfu Method
The gongfu method uses a small vessel, a higher ratio of leaf to water, and multiple short steeps. It’s the most common way to brew tea from a brick if you want to explore the full range of flavor.
Use about 5 grams of tea per 100 ml of water. For most brick teas (puerh, fu brick, dark tea), bring your water to a full rolling boil at 212°F. Pour it over the rinsed leaves, steep for 20 to 30 seconds on the first infusion, then pour off all the liquid into your cup. The second steep can be slightly shorter, around 15 to 25 seconds, since the leaves are now fully open. For each steep after that, add 10 to 15 seconds. A good brick tea can yield anywhere from five to ten or more infusions, with the flavor shifting noticeably from one round to the next.
You can use a gaiwan (a lidded bowl) or a small teapot. Either works. The key is keeping the vessel small so the tea stays concentrated without oversteeping.
Western-Style Brewing
If you’d rather make a single large mug, use less leaf and steep longer. A ratio of about 1 to 2 grams per 100 ml of water works well. Place your broken-off tea in a strainer or infuser, pour boiling water over it, and steep for 3 to 5 minutes. You’ll get fewer infusions this way (typically two or three), but the process is simpler and requires no special equipment beyond a mug and a strainer.
Traditional Recipes: Butter Tea and Milk Tea
Tea bricks weren’t designed for delicate steeping. For centuries across Tibet and Mongolia, they were boiled aggressively and combined with fat and salt.
Tibetan butter tea (po cha) starts by crumbling tea off a brick and boiling it in water for hours. Traditionally, an entire brick goes into a huge pot and simmers all day, with water added as it evaporates, until you’re left with a deeply concentrated liquid. That concentrate is then blended with yak butter and salt. At home, you can simplify this: boil a few tablespoons of crumbled brick tea in water for 15 to 20 minutes to get a strong base, strain it, then blend it with a tablespoon or two of butter and a pinch of salt until frothy.
Mongolian milk tea (suutei tsai) uses green tea bricks instead of black. The traditional approach is to boil a small amount of crumbled green brick tea in equal parts water and whole milk, roughly 2 cups of each, with salt added from the start. Let it simmer for 4 to 6 minutes, strain the leaves, and serve hot. Some versions include toasted millet cooked directly in the tea for 15 to 30 minutes, turning it into something closer to a porridge than a drink.
Spotting Mold vs. Golden Flowers
Some tea bricks, particularly fu brick tea, develop tiny golden-yellow specks throughout their layers. These are a beneficial fungus that tea producers deliberately cultivate during processing. It enhances the tea’s sweetness and gives it a malty, clean flavor. The specks are granular, bright amber, and distributed evenly within the brick’s interior.
Harmful mold looks completely different. It’s fuzzy, web-like, or slimy, and tends to appear in white, green, blue, or black patches on the brick’s surface. The smell is the clearest giveaway: spoiled tea smells musty, sour, or like a damp basement. If your brick smells that way, discard it. A healthy tea brick should smell earthy, woody, or slightly sweet, never fishy or rotten.
Storing Tea Bricks
Tea bricks, especially puerh, can improve with age if stored properly. The two variables that matter most are humidity and temperature. Aim for around 65% relative humidity and a room temperature between 65 and 75°F. At that humidity level, the tea retains enough moisture for slow biochemical aging without encouraging mold growth. For shou (ripe) puerh, you can go slightly drier, around 60 to 65%.
Below 65°F, the aging process nearly stops. Above the mid-70s, the tea ages faster but you risk drying it out or losing control of humidity. Store bricks away from strong odors (compressed tea absorbs smells readily), out of direct sunlight, and in a spot with some air circulation. A closet shelf in a room you keep comfortable works for most people. If your home is very dry, a small humidifier or a sealed storage container with a humidity pack can help maintain the right range.
Bricks you plan to drink within a few months don’t need any special treatment. Just keep them in a cool, dry place away from the spice cabinet and they’ll be fine.
