How To Culture Liquid Yeast

Using a liquid yeast is a great way to improve the quality of the beers you brew. Our range of “White Labs” pitchable brewers yeasts are as easy to use as the dried yeasts most of us are familiar with. At around $16.50 per vial it can add considerably to the cost of a brew so here is a way of making it more cost effective.

This is what you will need:-

A 2 litre bottle (a soft drink bottle will do).
A rubber band.
100g dry malt extract.
6 stubbies.

How to do it:-

About 4 hours before you start take your vial of liquid yeast out of the fridge and let it warm up to room temperature.
Wash and sterilise all your equipment and bottles.
Dissolve malt in 2 cups of boiling water; add 2 cups of boiling water.
Add water and leave to cool down to room temperature.
Shake the yeast to mix then add it to your bottle. Put glad wrap over the bottle top, secure with rubber band and put a small hole in the top with a pin then leave to ferment.
Because you have a large amount of yeast and a small amount of malt it won’t take long to ferment out, (around 24 to 48 hours.)
When it has finished fermenting gently stir and bottle into your clean & sterilised stubbies and cap. Use one to start up the beer you are brewing now and refrigerate the rest till you need them.
These starters should now last between 6 and 12 months in your fridge.

How to use:-

Take out of the fridge at least 4 hours before you plan to use the yeast then open and add to your brew. Ferment as per your normal method.
