A homemade vanilla soy drink tastes more intense than store-bought versions and contains no additives. The base is soy milk, enhanced with maple syrup and real vanilla. The drink is great on its own, as a coffee accompaniment, or as a base for dessert cocktails. Important: The beans must be thoroughly pureed and filtered, otherwise the drink will be grainy – a nut milk bag is the secret here.
And here’s what you need for the vanilla soy drink
200 g dried soybeans
1 litre water (plus extra for soaking)
30 ml maple syrup (adjust to taste)
1 tsp vanilla extract (or 1 scraped vanilla pod)
1 pinch of salt
Key points
The trick is in the second filtering: After heating, pour the drink through a fine sieve or coffee filter once more. This makes it silky-smooth and stable – especially important if you plan to use it later in cocktails like a Vanilla Soytini or a Matcha Latte. If using vanilla pods, add the pod itself to the pot after scraping and remove it only before bottling – this gives more aroma than the seeds alone.
Variations
- Chocolate soy drink — stir 2 tbsp unsweetened cocoa powder into the maple syrup. Pairs well with espresso.
- Cardamom-vanilla soy drink — heat 3 crushed cardamom pods with the soy drink and remove before straining. Adds a warm, spicy note.
- Iced coffee with vanilla soy drink — Shake chilled soy drink with 1 shot of espresso and ice cubes in a shaker. Dust with cocoa powder.
Frequently asked questions
Why does the soy drink curdle when heated?
Soy milk curdles if heated too strongly or comes into contact with acidic ingredients (e.g., lemon juice). Always stir at medium heat and do not boil. If it happens: Strain through a sieve and stabilize with a little starch (½ tsp cornstarch dissolved in water).
Can I make the drink without vanilla?
Yes, but vanilla rounds off the slightly beany flavour. Alternatively, cinnamon, tonka bean, or a pinch of nutmeg work well.
How long does homemade soy drink keep?
In the fridge, 3–4 days. Always shake before drinking as natural sediments settle. For longer shelf life, pasteurize: Heat the drink to 70 °C for 30 minutes, then pour hot into sterile bottles.
