How to Make Banana Café au Lait — Anaerobic Pour-Over Method

What you need

• pour-over dripper and paper filter
• coffee grinder
• kettle
• digital scale
• small cup or pitcher for banana mixture
• fork or small blender

Method

1. Grind 10 g of anaerobic-processed coffee at a setting slightly finer than your usual pour-over grind

   A cinnamon-forward anaerobic coffee is ideal; its intense aromatic character lets it function as a flavour ingredient rather than disappearing behind banana and sugar

   Expert tipSmell the dry grounds before brewing — a vivid cinnamon and honey scent signals the bean is expressive enough for this application

2. Set up your pour-over, rinse the filter, add the grounds, and brew: pour 70 g of 95 °C water first, then follow with a second pour of 50 g, and wait for the full extraction to drip through

   The two-stage pour is intended to draw a concentrated brew from a small 10 g dose

   Expert tipPause briefly after the first pour to let the grounds bloom — at this moment the cinnamon and honey aromas from the anaerobic processing are especially pronounced

3. While the coffee brews, place 50 g of ripe banana in a small cup, add approximately 10 g of the total milk, and mash thoroughly with a fork

   Adding only a small amount of milk at this stage prevents the excessive foam that forms when banana meets a larger volume of milk all at once

   Expert tipIf a small blender is available, blend the banana with the initial milk portion for a smoother texture; be aware that blending generates more foam, which can affect the drink's mouthfeel

4. Stir 15 g of raw or yellow sugar into the mashed banana until fully incorporated

   The sugar contributes body and helps bind the mixture; the point is not sweetness alone but how the sweetness interacts with the other components

5. Add 2 ice cubes to the banana-sugar mixture to cool it down

6. Add 10 g of banana concentrate and stir to combine

   Banana concentrate carries more actual fruit flavour and body than banana syrup, which tends to be more aromatic; syrup can be substituted but the profile will shift toward fragrance rather than taste

7. Pour the remaining milk into the banana base and stir gently to bring it together

   Total milk across both additions is 50 g

8. Divide the brewed coffee and the banana mixture between two glasses and stir each drink thoroughly before serving

   Mashed banana will not homogenise on its own — stir completely before each sip

   Expert tipAny texture from banana pieces mid-drink is part of the drink's character; the creator describes it as a distinctive and appealing contrast

Why this works

Using only 10 g of coffee demands a highly expressive bean — the anaerobic processing amplifies aromatic compounds, particularly cinnamon and honey notes, making them legible even against sweet and fruity ingredients. Brewing by pour-over rather than espresso keeps the extraction thinner and more aromatic, matching the lighter body of classic café au lait. Mashing the banana with a small amount of milk first controls foam formation and creates a paste that disperses more evenly through the drink. Banana concentrate supplements the fresh banana with depth of actual fruit flavour, while banana syrup would add fragrance only.

Where beginners go wrong

1. 1

   Excessive foam when mixing banana and milk

   Add only a small amount of milk — around 10 g — when mashing the banana, and hold back the rest until after the sugar and concentrate are incorporated. Combining banana with a large volume of milk at once creates significantly more foam.

2. 2

   Banana will not blend smoothly into the drink

   Mash the banana as thoroughly as possible before adding any other components. A small blender used on the banana-and-milk portion produces a finer paste; alternatively, stir the assembled drink very well — it does not self-combine.

3. 3

   Coffee flavour disappears behind banana and sugar

   Choose an anaerobic-processed coffee with a strong, distinct aroma — cinnamon and spice-forward profiles are recommended. A mild or balanced bean will not register against assertive sweet ingredients.

4. 4

   Drink tastes flat even with quality components

   Good individual ingredients do not automatically make a good combined drink. Taste the banana base and the brewed coffee separately first, then assess the balance before joining them; adjust the concentrate or sugar level if either element is overpowering.

What you should taste

The drink opens with vivid cinnamon and honey aromas carried by the anaerobic coffee. Banana is present as both flavour and gentle texture from the mashed fruit. At the finish, the coffee's intensity cuts through the sweetness and richness of the banana, preventing the drink from feeling cloying. Cinnamon, banana, and coffee are described as working in harmony rather than competing, with each component playing a distinct role.
