Common Green Tea Mistakes
Why your green tea tastes bitter: the five most common mistakes. Water too hot, steeping too long, wrong ratio, stale tea, and poor water quality.
Introduction
Green tea has a reputation for bitterness that is largely undeserved — it is the result of brewing errors, not inherent character. When prepared correctly, quality green tea is sweet, smooth, and complex. Here are the five most common mistakes and their corrections.
Mistake 1: Water Too Hot
This is the single most destructive error. Pouring boiling (100 C) water on green tea extracts catechins at 3-4 times the rate of 70 C water, flooding the cup with harsh astringency. Fix: Use 65-80 C for most green teas. Invest in a variable-temperature kettle — it will transform your green tea experience within a single cup.
Mistake 2: Steeping Too Long
After temperature, time is the second most impactful variable. Leaving green tea in water for 5 minutes when it needed only 60-90 seconds extracts deep, bitter tannins that overwhelm subtle flavors. Fix: Time your steeps. Start with 60 seconds and adjust to taste. Remove the leaves completely when the steep is done — a strainer basket or gaiwan allows clean separation.
Mistake 3: Too Much Leaf
Excessive leaf-to-water ratio concentrates every compound, including bitter catechins. Fix: Use 2-3 grams per 150ml for Western brewing. A kitchen scale is more accurate than volumetric scoops, since leaf density varies enormously between rolled, flat, and needle-shaped teas.
Mistake 4: Stale Tea
Green tea is the most perishable tea category. After 6-12 months, catechins oxidize, amino acids degrade, and chlorophyll breaks down. Stale green tea tastes flat, dusty, and unpleasantly astringent. Fix: Buy from vendors with harvest dates. Purchase in small quantities (50-100g). Store properly: opaque, airtight container in a cool, dark place.
Mistake 5: Bad Water
Hard water suppresses green tea's brightness and creates a chalky film. Chlorinated water introduces off-flavors that are more noticeable in delicate green tea than in robust black tea. Fix: Use filtered water with 50-150 ppm TDS. If your tap water tastes of chlorine, a simple carbon filter solves the problem.
