Leaf-to-water ratios

Here’s a TESDA- and Oud Academia–aligned module on Leaf-to-Water Ratios for agarwood leaf tea, designed for food-grade, non-resin leaves, for consistent brewing, sensory quality, and export-ready standards.


Leaf-to-Water Ratios

Food-Grade Agarwood Leaf Tea


1. Core Principle

“Correct leaf-to-water ratio ensures balanced aroma, flavor, and bitterness.”

Even premium agarwood leaves can produce overly bitter or weak tea if the leaf-to-water ratio is incorrect. Standardized ratios allow consistent infusion, optimal extraction of bioactives, and a pleasing sensory profile.


2. Recommended Ratios

Tea FormatLeaf WeightWater VolumeNotes
Loose Leaf (Green / Semi-Fermented)2–3 g150 mL (1 cup)Standard cup brewing; adjust steeping time for aroma control
Tea Bag (Single-Serving)2 g150–200 mLEnsure tea bag fill matches particle size (broken leaves or fannings)
Functional Blend2–3 g total150–200 mLMaintain agarwood as primary ingredient, scale companion herbs proportionally
Bulk Brewing (Multiple Cups)10 g1 LUse standardized ratios to maintain consistent flavor across batch

Note: Ratios can be adjusted slightly for stronger aroma or milder flavor, but must remain documented for traceability and quality control.


3. Brewing & Sensory Guidelines

  • Steeping Time: 3–5 minutes (green), 4–6 minutes (semi-fermented)
  • Water Temperature: 80–90°C (green), 85–95°C (semi-fermented)
  • Agitation: Gentle swirl; avoid crushing leaves in cup
  • Sensory Evaluation: Check color, aroma, bitterness, and finish

4. TESDA-Aligned Learning Outcomes

Learners will be able to:

  1. Calculate correct leaf-to-water ratios for different tea formats
  2. Adjust ratios for functional blends and single-origin teas
  3. Integrate ratios into sensory evaluation for bitterness, aroma, and finish
  4. Document brewing ratios for batch consistency and export compliance
  5. Train others in standardized brewing techniques for consumer satisfaction

5. Integration with Other Modules

  • Moisture & Particle Size: affects infusion strength and extraction rate
  • Oxidation Control: ratio adjustments may be needed for semi-fermented leaves
  • Functional Blends: scale water proportionally to maintain flavor balance
  • Water Quality: leaf-to-water ratio interacts with mineral content to influence taste

6. Regulatory & Export Notes

  • FDA-PH and ASEAN require accurate ingredient listing and batch documentation, including:
    • Leaf-to-water ratio guidance for consumers (optional)
    • Sensory and quality consistency across batches

7. Training Disclaimer

This module applies exclusively to food-grade agarwood leaves.
Resin and medicinal claims are outside the scope of leaf-to-water ratio guidance.


✅ Ideal For:

  • TESDA CBLM & brewing modules
  • Oud Academia premium tea preparation courses
  • Plantation SOPs for functional blends, single-origin, and sensory evaluation
  • Export-ready food-grade herbal teas

I can next create:

  1. A visual infographic showing leaf-to-water ratios for cups, tea bags, blends, and bulk brewing
  2. A brewing guide template for training or consumer instruction
  3. Integration into TESDA submission package with moisture, oxidation, particle size, and sensory modules
