The key to getting the most out of your fresh wort kit is care with fermentation. Be kind to your yeast!
Rehydrating dried yeast, and giving them plenty of oxygen on pitching will ensure a healthy fermentation and a better tasting beer. Here is a way to do that.
- Sanitise a clean fermenter with a no rinse sanitiser.
- Spray the sachet of yeast and a pair of scissors with sanitiser.
- Add 1 litre of tepid or slightly warm water – say 25 to 30°C, to the fermenter.
- Open the sachet of yeast and sprinkle it evenly over the entire surface of the water. Place the lid back on the fermenter.
- Wait five minutes for the yeast to rehydrate.
- Spray the lid of the wort kit with sanitiser, open and pour into the fermenter. Hold the drum on its side to get a smoother pour. Work the drum up and down as you pour to froth up the wort in the fermenter.
- Add a further two litres of water to the fermenter to bring up the volume to 20 litres.
If you can, use a hose to add the water. Hold your clean thumb over the end of the hose and spray the water in hard. This will get plenty of air into the wort which will froth up. It will also mix the wort and water.
If you are adding the water from a jug, then pour it in from a height to froth up the wort. Next take a sanitised mixing spoon and stir the wort vigorously working air into it.
These are easy measures to take. You will probably find that fermentation will take about the same time to start as normal. However, the result will be a much smoother and more mellow tasting beer.
The other kindness to give your yeast is a stable temperature. If you are half-way serious about your brewing then a fridge with an adjustable temperature controller is essential. It will allow you to brew all through summer. Even in milder seasons when you can brew at ambient temperatures, a fridge and temperature controller will provide a stable temperature which will benefit fermentation.
