All dried brewing yeasts are suitable for adding directly to your wort by sprinkling onto the surface of the liquid. However, you can get the fermentation going quicker and more vigorously by starting your yeast first. Here's how you do this.
- Start with 100ml of water that has been boiled and cooled to 25°C - 30°C (for ales) or 20°C - 25°C (for lagers). Use a sterilised thermometer to check the temperature.
- Sprinkle the yeast onto the surface and stir gently.
- Wait for 15min, swirling the mixture occasionally.
- Add 1 heaped teaspoon of dry malt extract powder and stir to dissolve.
- Wait for 30min then swirl the mixture to lift the yeast off the bottom and add it all to the wort in your fermenter.
