Recipe Development¶
Recipe development is the skill of creating and refining brew recipes — the specific parameters (dose, yield or ratio, temperature, time, grind) used to produce a coffee — for a given coffee and brew method. It combines extraction knowledge, sensory evaluation, and systematic experimentation to find the parameters that best express a specific coffee's character.

What a Recipe Is¶
A coffee recipe is a complete specification of the variables that define a brew:
For espresso: Dose (g in), yield (g out), extraction time (seconds), water temperature (°C), grind setting (relative)
For filter: Coffee dose (g), water volume (g or ml), ratio (e.g. 1:16), water temperature (°C), total brew time (minutes), bloom volume and time (if applicable)
A recipe is not universal — the optimal recipe for a washed Ethiopian pour over is not the optimal recipe for a natural Brazilian. Recipe development means finding the right recipe for a specific coffee, not applying a fixed formula to everything.
Starting Points¶
Begin from a well-tested baseline:
| Method | Starting Recipe |
|---|---|
| Espresso | 18g / 36g / 28–30s / 93°C |
| V60 | 15g / 250g water / 1:16.7 / 93°C / 3:00 |
| AeroPress | 15g / 200g water / 80°C / 2:00 steep / press 30s |
| French Press | 30g / 500g water / 93°C / 4:00 |
| Cold brew | 100g / 700g cold water / 18 hours |
These are starting points only. The development process adjusts from here based on taste.
The Development Process¶
Step 1: Brew to the Baseline¶
Brew at the starting recipe and taste carefully. Note: - What is good about this cup? - What is lacking or imbalanced? - Is the issue under-extraction (sharp, thin, sour, lacking sweetness) or over-extraction (bitter, dry, hollow)?
Step 2: Hypothesise¶
Based on the diagnosis, form a clear hypothesis: - "This is slightly under-extracted — I'll try a finer grind to increase extraction" - "The acidity is too sharp — I'll reduce the water temperature to soften it" - "The body is too thin — I'll increase the dose slightly"
Step 3: Change One Variable¶
Change exactly one variable at a time. If you change two simultaneously and the cup improves, you do not know which change caused the improvement — or whether one change improved while the other harmed.
Step 4: Compare Side by Side¶
Brew the adjusted recipe alongside the baseline and taste them simultaneously. Differences that are difficult to detect in isolation become obvious in direct comparison.
Step 5: Document and Iterate¶
Record every brew: the recipe, the taste result, and the conclusion. This creates a development log that makes the next iteration faster and prevents repeating the same experiments.
Lever Relationships¶
Understanding how variables interact:
| Change | Primary Effect | Secondary Effect |
|---|---|---|
| Finer grind | Higher extraction | Longer brew time (filter) or slower flow (espresso) |
| Higher temperature | Higher extraction | Can increase bitterness |
| More coffee (dose) | More body, slower extraction | Higher cost, stronger cup |
| Longer time (filter) | Higher extraction | Can increase bitterness/astringency |
| Higher yield (espresso) | More water contact, higher extraction | More dilute cup |
| Lower ratio (more coffee to water) | Stronger, more concentrated | Higher extraction rate |
Adapting Recipes to Coffee Characteristics¶
Light roasts: Dense, slow to extract, often high in acidity. Benefit from: finer grind, higher temperature (94–96°C), higher yield (espresso), longer brew time (filter).
Dark roasts: Soluble, fast to extract, low acidity, high bitterness potential. Benefit from: coarser grind, lower temperature (88–91°C), lower yield, shorter brew time.
Natural/anaerobic coffees: Rich, fruity, sometimes sweet. May need lower extraction to preserve fruit character without becoming syrupy or fermented-tasting.
Washed coffees: Clean, bright, structured. Benefit from the full extraction range — take time to find the balance point where sweetness and acidity are both present.
Signature Recipes¶
At Level 3, recipe development includes creating signature drinks — original espresso or filter recipes that go beyond the standard menu. A signature recipe might involve:
- A specific ratio designed for one particular coffee
- An unusual temperature that highlights a specific attribute
- A blended recipe combining two coffees for a specific flavour goal
- A filter recipe designed for serving cold that accounts for the flavour shift of cold serving temperature
Assessment¶
An Advanced Barista should be able to: - Start from a baseline recipe and systematically develop an optimised recipe for a new coffee - Change one variable at a time and articulate the hypothesis being tested - Document the development process and the reasoning for each decision - Produce a final recipe with sensory notes explaining why each parameter was chosen
