About this calculator
The Tea Preparation Calculator is a practical tool to determine the ideal amount of tea, water temperature, and steeping time for different types of tea. It follows standard recommendations: 1 teaspoon (about 2 grams) per 200 ml cup. For green tea, the recommended temperature is 75°C with a 2-minute steep; for black tea, 95°C for 4 minutes; and for herbal infusions, 100°C for 5 minutes. These parameters help extract the best flavor and avoid bitterness.
How it works: simply select the tea type (green, black, or herbal) and enter the desired number of cups. The calculator displays the amount of tea in teaspoons, water temperature in Celsius, and steeping time in minutes. The calculation uses fixed proportions for each type, ensuring consistent results.
When to use: perfect for anyone wanting to prepare quality tea, whether daily or for guests. Useful for beginners who don't know the correct measurements and for enthusiasts seeking standardized preparation. Also handy for adjusting recipes that call for tea as an ingredient.
Cautions: water temperature is critical; too hot water can burn delicate teas like green, while cold water fails to extract compounds properly. Use a kitchen thermometer if possible. Steeping time must be respected to avoid bitterness. For tea bags, the same logic applies, but the amount per cup is already defined.
Frequently asked questions
Can I use the same temperature for all teas?
No, each tea type has an ideal temperature. Green tea needs cooler water (75°C), black tea needs hot water (95°C), and herbs need boiling water (100°C). Wrong temperature can result in bitter or weak flavor.
How many teaspoons should I use for a large cup?
The calculator considers 200 ml cups. If your cup is larger, increase the amount proportionally. For example, for 300 ml, use 1.5 teaspoons.
Does steeping time vary if I use tea bags?
Generally no, the recommended time is the same. However, tea bags usually have the right amount for one cup, so you don't need to measure.
How can I measure water temperature without a thermometer?
For 75°C, boil water and let it rest for 2-3 minutes. For 95°C, boil and wait 30 seconds. Boiling water is 100°C, use immediately.
Can I reuse tea leaves?
Yes, some leaves can be reused, but the steeping time should be longer (about 30 seconds more) and the flavor will be milder.
