From Competition Recipe to Cafe Recipe: Carry the Principles, Not the Numbers
Turning competition thinking into cafe numbers
Written by Chanho Hong
What this chapter covers
What to take from a WBC or WBrC competition recipe and what to change for the cafe: the difference in conditions, three principles worth keeping, five translation steps and a worked example.
A competition is a stage for a few perfect cups in a fixed time; a cafe is a floor where many similar cups go out all day. So what you take from a competition recipe is its principles, not its numbers, and the cafe recipe is rebuilt around reproducibility.
Competition and cafe aim at different things
Reproducibility is the ability to make the same cup when people, time and coffee lots change.
In the WBrC open service, after five minutes of preparation, the competitor serves three identical drinks within ten minutes, and the head judge scores their uniformity separately. In WBC round one, the competitor serves twelve drinks in fifteen minutes: four espresso, four milk and four signature. Both assume short time, few cups and ideal conditions (Chapters 12 and 13).
| Item | Competition | Cafe |
|---|---|---|
| Cups | Three to twelve | Tens to hundreds a day |
| Time | 10 or 15 minutes | All trading hours |
| Who brews | One competitor | Several staff |
| Water | Designed water | The shop's filtered water |
| Coffee | Small competition lot | A coffee supplied week after week |
| Goal | One high score | A similar cup every time |
Three principles worth taking from a competition recipe
A routine starts from one sentence about what the coffee should show, then the recipe follows. In a cafe, a goal such as "sweetness arrives before acidity" keeps every adjustment pointed the same way.
Competitors measure ratio, grind, temperature and time to serve three identical cups. A cafe recipe card needs every line written as a number so the cup survives a change of staff.
Change a single variable on the same coffee and recipe and compare blind. In a cafe, if you move the grind, leave everything else alone and taste (Chapter 8, Correlation).
Five steps from competition to cafe
| Step | What to do | Why |
|---|---|---|
| 1. Change the water | Re-taste with your shop water | The same recipe tastes different on different water |
| 2. Widen tolerances | Use ranges such as 2:10~2:30 | Ranges can be held during a rush |
| 3. Simplify the pour | Drop moves that barely change the result | Fewer moves, less staff-to-staff variation |
| 4. Choose the coffee | Build the recipe on a coffee you can keep buying | The card stays useful for longer |
| 5. Card and opening check | Measure the first cup and record the taste | A baseline is how you notice drift (Chapter 10, QC) |
"A competition recipe is a better recipe." It is the best recipe for that stage's conditions. Change the water, the people or the coffee and the same cup does not come out.
Example: the cafe recipe for a single origin roasted on a competition profile
MTSPACE roasts its single origins on the same light profile it uses in competition, and publishes a reference recipe for each coffee that a cafe can start from straight away.
Roast. Light profile: first crack at 6:30, +5℃ after crack, 45 seconds of development.
Cafe reference recipe. Filter (V60) 15g, grind 700, 45g bloom for 90s, 225g total, 2:10~2:30. Espresso 18g to 43g in 24s. Milk 20g to 40g in 26s with 150ml milk.
How to read it. Time is a range; everything else is a fixed number. Re-find the grind on your own grinder and leave the rest as written.
Questions this chapter answers
- Can I use a competition recipe as it is in my cafe?
- You can, but once the water, the staff or the coffee changes, the same cup does not come out. Take the principles and re-tune them to your shop's conditions.
- What should I take from a competition recipe?
- Three principles: write the taste goal as a sentence, fix every variable as a number, and change one thing at a time before tasting.
- The cup changes from barista to barista. Where do I start?
- Start with a recipe card written in numbers and an opening check that measures the first cup. If the pour is complicated, drop the moves that barely change the result.
