About African Tea Made Tea Yield
Estimate Made Tea Output from Fresh Green Leaf
In the African tea industry, the term "made tea" refers to processed, dried tea ready for auction or sale - as distinct from fresh green leaf harvested in the field. The African Tea Made Tea Yield tool on ToolWard helps tea farmers, factory managers, and estate planners calculate how much made tea they will produce from a given quantity of freshly plucked green leaf. This ratio is arguably the most important metric in tea manufacturing economics.
Understanding the Green Leaf to Made Tea Ratio
Fresh tea leaves contain approximately 75-80% moisture. The manufacturing process - withering, rolling or CTC (crush-tear-curl), oxidation, and drying - removes most of this moisture while transforming the leaf into finished black tea. The industry-standard conversion ratio is approximately 4.2:1 to 4.5:1 in East Africa, meaning 4.2-4.5 kg of green leaf produces 1 kg of made tea. However, this ratio varies with leaf quality, weather conditions at harvest, factory efficiency, and the type of tea being produced.
How to Use the African Tea Made Tea Yield Tool
Enter the weight of green leaf delivered to the factory. Select your tea type (CTC black tea, orthodox black tea, green tea, or white tea - each has different conversion ratios). The tool calculates your expected made tea output, moisture removed, and effective cost per kilogram of made tea if you provide your green leaf purchase price.
Factory managers can enter multiple deliveries or daily intake volumes to plan weekly or monthly production targets. The tool also shows how changes in the green-to-made ratio affect output - a shift from 4.5:1 to 4.2:1 on a 100-tonne green leaf intake means an extra 1.6 tonnes of made tea, which at auction prices can represent significant additional revenue.
Who Benefits from This Tool?
Tea factory managers in Kenya, Malawi, Tanzania, Uganda, and Rwanda use made tea yield as a daily performance metric. If your factory's ratio deteriorates, it could indicate problems with withering trough calibration, dryer temperature, or incoming leaf quality. This tool provides a quick benchmark. Smallholder tea farmers supplying green leaf to factories can use it to understand how much their leaf contributes to the factory's made tea output - and whether the price per kg of green leaf fairly reflects the made tea value.
Tea estate managers planning seasonal production use the tool to convert field yield estimates (green leaf per hectare) into made tea projections for budgeting and sales commitments. Tea auctioneers and brokers tracking supply forecasts also find it useful.
Real-World Scenario
A KTDA-affiliated factory in Kericho, Kenya, receives 80,000 kg of green leaf per day during peak season. Using the tool with a CTC ratio of 4.35:1, the projected daily made tea output is 18,391 kg. At an average auction price of $2.50 per kg, that represents $45,977 in daily revenue. The factory manager uses this estimate alongside actual production data to monitor efficiency and detect deviations promptly.
Tips for Optimising Made Tea Yield
Pluck fine - two leaves and a bud give the best made tea quality and consistent conversion ratios. Transport green leaf quickly to the factory; wilted or overheated leaf at intake leads to poor withering and higher-than-normal moisture retention. Calibrate dryers carefully - over-drying wastes weight, under-drying risks mould. Monitor ratio daily and investigate any shift beyond the normal 0.1-0.2 point range immediately.
From Field to Auction, Know Your Numbers
The African Tea Made Tea Yield tool bridges the gap between green leaf harvested and made tea produced. It is calibrated for African tea-growing conditions and factory practices. Free, browser-based, and instant - it belongs in every tea professional's toolkit.
