Calculate Tea & Coffee Strength for Any Brewing Style

This Tea & Coffee Strength Calculator combines four practical modes in a single tool. Use professional brew ratio and TDS inputs, or keep it simple with spoons and cups. You can switch between coffee and tea, and there is also a barista mode with extraction yield for dialing in espresso or filter coffee.

Typical coffee brew ratios are around 1:15–1:17 (1 g of coffee per 15–17 g of water). Tea is often brewed milder, but steep time matters more. Professional coffee strength is commonly measured with TDS (total dissolved solids) in the range of 1.15–1.45% for many filter brews.

Brew ratio is computed as water divided by dose (for example 270 g water and 18 g coffee gives a ratio of 1:15). Extraction yield is approximated from the simple relation EY% ≈ TDS% × (beverage mass / dose). Here we use your entered water amount as a proxy for beverage mass, which works well for quick tuning.

This mode is designed for quick home use. It assumes 2 grams of tea or coffee per teaspoon. It converts spoons and cups into an approximate brew ratio and then classifies your drink as weak, balanced, or strong, with easy suggestions on how to adjust next time.

This mode compares your current dose, water volume and steep time with typical ranges for coffee and different types of tea. It returns a simple verdict (too weak, balanced, or very strong) and explains whether you should mainly adjust time, amount, or water next time.

This mode is aimed at baristas and advanced home brewers. It uses your dose, beverage yield and TDS to compute brew ratio and extraction yield. It then compares the numbers with the classic “brew control chart” style ranges (about 18–22% extraction yield and 1.15–1.45% TDS for many filter coffees).

Tea & Coffee Strength Calculator Formula or Method

  • Brew strength depends on the ratio of coffee or tea to water. A simple dose ratio is brew ratio = water amount ÷ dry coffee or tea amount . Extraction, grind, steep time and brewing method can change perceived strength even at the same ratio.
