Green Tea — Western Brewing Guide
Pro Tip
Never use boiling water for green tea. Water that is too hot will scorch delicate leaves and create a bitter, astringent cup. Let boiling water cool for 2-3 minutes before pouring.
How Tea to Water Ratio Works
The tea to water ratio determines how much loose leaf tea you use relative to the volume of water, directly controlling the strength, body, and flavor of your cup. A stronger ratio like 1:15 produces a concentrated, full-bodied brew, while a lighter ratio like 1:60 delivers a delicate, refreshing infusion. Different tea types have different ideal ratios because leaf density, surface area, and flavor intensity vary widely between green, black, white, oolong, and herbal teas.
The ratio also depends heavily on your brewing style. Western brewing uses a larger vessel with more water and a single longer steep, requiring less tea per volume (typically 2-3 grams per 240ml). Gongfu brewing uses a small vessel like a gaiwan with less water but significantly more tea (5-8 grams per 100ml), producing a concentrated liquor designed for multiple short infusions that each reveal different flavor layers.
Tea Ratios for Western vs Gongfu Brewing
Western brewing is the most common method worldwide. You add tea leaves to a teapot or infuser, pour hot water, and steep for 2-5 minutes depending on the tea type. The standard ratio ranges from 1:40 for robust black teas to 1:60 for delicate white teas. This produces a single full-flavored cup that is ready to drink without dilution. Most tea bags are pre-portioned for Western brewing at approximately 2 grams per 240ml cup.
Gongfu brewing originated in China and uses significantly higher leaf-to-water ratios. A typical gongfu session uses 5-8 grams of tea per 100-150ml of water, with multiple infusions lasting just 10-30 seconds each. The first infusion is sometimes discarded as a rinse. Each subsequent infusion extracts different flavor compounds, making gongfu ideal for high-quality oolong, pu-erh, and Chinese green teas where you want to explore the full range of flavors a single batch of leaves can offer.
Temperature and Steep Time by Tea Type
Water temperature is just as important as ratio. Green and white teas are the most heat-sensitive, requiring water between 160-185°F (71-85°C). Pouring boiling water on green tea will burn the leaves and create a bitter, unpleasant taste. Black tea and herbal infusions can handle full boiling water at 200-212°F (93-100°C) because their leaves are more oxidized and robust. Oolong falls in between at 185-205°F (85-96°C), with lighter oolongs needing cooler water and darker roasted oolongs tolerating higher temperatures.
Steep time works alongside ratio to control extraction. Over-steeping any tea leads to excessive tannin release and bitterness. Green tea typically needs 2-3 minutes in Western style, while black tea can steep 3-5 minutes. Herbal infusions often need the longest steep at 5-7 minutes because they contain no actual tea leaves and extract flavor more slowly from dried herbs, flowers, and roots. In gongfu style, steep times start at just 10-15 seconds and increase by 5-10 seconds with each subsequent infusion.
Tips for Measuring Tea Accurately
Weighing tea with a digital scale is the most accurate method, especially for loose leaf tea where volume varies dramatically by leaf size. One gram of tightly rolled oolong takes up far less space than one gram of fluffy white tea. If you do not have a scale, use approximately one teaspoon per cup for small-leaf teas (green, black) and one tablespoon per cup for large-leaf or fluffy teas (white, some oolongs). Always adjust by taste after your first brew — if the tea tastes too strong, use less leaf or more water next time. If it tastes weak and watery, increase the leaf amount or reduce water volume.
2026 Specialty Tea Association Brewing Standards
The Specialty Tea Association publishes the most cited Western brewing reference: 2.25 grams of leaf per 6 ounces (177 ml) of water, which is a 1:78 ratio for sensory cupping but adjusts to 1:50 for everyday drinking. The International Tea Importers / ITTA professional brewing guideline for 2026 confirms the same baseline and adds tea-specific adjustments: 1:40 for fully oxidized black tea, 1:50 for partially oxidized oolong, 1:55 for green tea, and 1:60 for delicate white tea. Gongfu ratios in the 1:15 to 1:20 range — long the standard in Chinese tea houses — gained formal recognition in the Specialty Tea Association 2024 brewing guide and remain unchanged for 2026. Once you have your ratio, dial in the rest of the brew with the tea brewing temperature guide, time it precisely with the tea steeping timer, and check the tea caffeine calculator if caffeine intake matters. For matcha specifically, switch to the matcha ratio calculator since whisking ratios differ from leaf-tea brewing.
2026 Tea-to-Water Ratio Update by Tea Type
For 2026, the verified ratio table from the Specialty Tea Association and ITTA is: black tea 1:40 (240 ml water + 6 g leaf), oolong 1:45-50, green tea 1:50-55, white tea 1:55-60, pu-erh 1:40, herbal 1:40, and matcha 1:30 to 1:60 depending on usucha vs koicha preparation. These are starting points — Specialty Tea Association sensory research shows that personal preference shifts the optimal ratio by 20 percent in either direction without crossing into bitter or weak territory, so use the calculator above as a baseline and adjust by half a gram at a time. If you are blending your own herbals or scaling for cold brew, use the herbal tea blend builder; for pitcher-style iced tea where ice melt dilutes the brew, the iced tea dilution calculator back-calculates the stronger starting concentrate. Once you find your perfect ratio, log it in the tea collection tracker so you never have to retest the same tea twice.

Cold Brew Tea Ratios — Overnight Method
Cold brew tea uses the same leaf types as hot brewing but extracts flavor with cold or room-temperature water over 6–12 hours rather than minutes of heat. Because cold water extracts caffeine and tannins far more slowly, you typically need a stronger starting ratio to achieve satisfying flavor. The cold brew standard from the Specialty Tea Association is approximately 1:20 to 1:25 — roughly double the leaf you would use for a hot Western brew. Green tea cold brew is particularly forgiving at 1:20 (5 g per 100 ml), producing a sweet, almost grassy cup with almost none of the bitterness that hot water can trigger. Black tea cold brew works best at 1:20 to 1:22 and should steep no longer than 12 hours to avoid astringency buildup. White tea is excellent at 1:25 steeped 8 hours. All cold brews should be refrigerated during steeping; remove leaves once the flavor reaches your preferred strength. The iced tea dilution calculator helps you account for ice melt if serving over ice.
How Water Hardness Affects Your Tea Ratio
Water mineral content — specifically calcium and magnesium hardness — significantly influences how tea extracts and how strong the same ratio will taste. Hard water (above 150 ppm total dissolved solids) suppresses the perception of sweetness and floral notes in green and white teas, making them taste flat even at the correct ratio. It also accelerates tannin precipitation in black tea, causing the cloudy "cream" layer that forms when tea cools. In hard water areas, reducing your ratio by roughly 10 percent (for example, 1:55 instead of 1:50 for green tea) and filtering or using bottled water at 50–100 ppm TDS will produce a cleaner, brighter cup. Very soft water (under 30 ppm) can make tea taste thin and hollow — a small pinch of mineral-rich sea salt (literally one or two granules per cup) is a traditional UK fix that rounds out the flavor. The World Tea Academy recommends water in the 50–150 ppm range as optimal for all tea types. If your tap water is heavily chlorinated, let it stand for 30 minutes or use a filter — chlorine interferes with volatile aromatic compounds and is the single most common reason a technically correct ratio still produces an off-tasting cup.
Frequently Asked Questions
What is the standard tea to water ratio?
The standard Western tea to water ratio is approximately 1:40 to 1:60, which translates to 2-3 grams of loose leaf tea per 240ml (8oz) cup of water. Black tea is typically brewed stronger at around 1:40, while delicate green and white teas use a lighter 1:50 to 1:60 ratio. Gongfu brewing uses a much stronger ratio of 1:15 to 1:20.
How much loose leaf tea per cup?
For a standard 240ml (8oz) cup, use 2-3 grams of loose leaf tea for Western brewing. One teaspoon of small-leaf tea (like green or black) weighs about 2-3 grams. Large-leaf teas like white tea or some oolongs are fluffier, so you may need a tablespoon to reach the same weight. For the most consistent results, use a kitchen scale.
What is the difference between Western and Gongfu brewing?
Western brewing uses more water and less tea (2-3g per 240ml) with a single long steep of 2-5 minutes. Gongfu brewing uses more tea and less water (5-8g per 100ml) with multiple very short infusions of 10-30 seconds. Gongfu extracts different flavors with each infusion, making it ideal for exploring high-quality oolongs and pu-erh teas.
Why does water temperature matter for tea?
Water temperature controls which compounds are extracted from tea leaves. Boiling water (212°F/100°C) is perfect for black tea and herbal infusions, but it scorches delicate green and white tea leaves, releasing excess tannins that create bitter, astringent flavors. Green tea needs 170-180°F (77-82°C), white tea needs 160-185°F (71-85°C), and oolong varies from 185-205°F (85-96°C) depending on oxidation level.
Can I reuse tea leaves for multiple infusions?
Yes, most high-quality loose leaf teas can be steeped multiple times. In gongfu brewing, this is the standard practice — oolong and pu-erh can yield 5-10 infusions. In Western brewing, green and oolong teas can typically be re-steeped 2-3 times by adding 30-60 seconds to each subsequent steep. Black tea is usually good for 1-2 steeps. Herbal teas generally only produce one good infusion.
How do I adjust the ratio if my tea tastes bitter or weak?
If your tea tastes bitter, you are likely over-extracting. Use less tea, lower water temperature, or shorter steep time. If your tea tastes weak and watery, use more tea leaves, slightly hotter water, or a longer steep time. Adjusting the leaf amount is the easiest method. Start with the recommended ratio and change by half a gram at a time until you find your preferred strength.
What is the official Specialty Tea Association tea-to-water ratio for 2026?
The Specialty Tea Association cupping standard for 2026 remains 2.25 grams of leaf per 6 ounces (177 ml) of water — roughly a 1:78 ratio used for professional sensory evaluation. For everyday drinking, the International Tea Importers / ITTA professional guideline recommends 1:40 for black tea, 1:45-50 for oolong, 1:50-55 for green tea, and 1:55-60 for white tea. Gongfu ratios of 1:15 to 1:20 also gained formal recognition in the Specialty Tea Association 2024 brewing guide and remain the 2026 standard.
How do I scale the tea ratio for a teapot or pitcher in 2026?
Multiply both sides of the ratio. For a 1-liter (1000 ml) Western brew at 1:50, you need 20 grams of leaf — about 4 teaspoons of small-leaf tea or 4 tablespoons of fluffy white tea. For cold brew pitchers, use the same ratio but extend the steep to 8-12 hours in the refrigerator. For iced tea where you will pour over ice, double the leaf amount (effectively a 1:25 ratio) so the melting ice dilutes back to a normal 1:50 strength. Always weigh leaf with a digital scale for repeatable results across different sized vessels.
What is the best tea to water ratio for cold brew tea?
Cold brew tea requires roughly double the leaf of hot Western brewing because cold water extracts flavor more slowly. The Specialty Tea Association cold brew standard is 1:20 to 1:25 — about 4-5 grams per 100 ml of cold water. Green tea cold brews well at 1:20 for 6-8 hours in the refrigerator. Black tea works at 1:20 for up to 12 hours. White tea uses 1:25 for 8 hours. All cold brews should steep in the refrigerator to prevent bacterial growth, and leaves should be removed once the desired strength is reached to avoid bitterness developing overnight.
Does water hardness affect the tea to water ratio?
Yes, water mineral content significantly changes how tea extracts. Hard water above 150 ppm total dissolved solids suppresses sweetness and floral notes, making tea taste flat at the standard ratio. In hard water areas, reduce your ratio by about 10 percent (use 1:55 instead of 1:50 for green tea) and consider filtered or bottled water at 50-100 ppm TDS. The World Tea Academy recommends water in the 50-150 ppm range as optimal for all tea types. Heavily chlorinated tap water also interferes with tea aroma — let it stand 30 minutes or use a filter before brewing.
