Liquid Brewing Yeast and its effects on your brew
There has been much debate in the home brewing community as to whether or not liquid yeast is better to use than its dry counterpart. Seeing that we have just introduced Liquid yeast to our stores, perhaps it’s worth a bash to have a look at both the pros and cons with regards to its claims of superiority.
Why use liquid yeast instead of dry yeast? Well put simply, it is far more pure and it all lies in the variety of liquid cultures. If you think of it logically, dry yeast does in fact, contain a certain level of contamination as sterilization is practised in the form of fluids. This is no doubt a minor plus –side to utilizing liquid yeast.
However, there is a downside and it can be quite cumbersome if utilization and refrigeration is ignored. Good quality Liquid Yeast only has a shelf life of 4 months. This is because yeast is a living, breeding organism and it is essential that they are placed in their favourable conditions in order to flourish. Dry yeast on the other hand, can live up to a year – having twice he shelf life of its liquid form. This boils down to one important factor regarding liquid yeast – although it is better where beer taste is concerned, it is certainly more perishable.
Now for the storing of your yeast. Liquid yeast MUST be placed in a refrigerator prior to use in order to keep it fresh and alive for a wee longer. Then, remove the yeast approximately 6-8 hours before you intend to pitch. This is to insure that the yeast does not go into temperature shock. However, dry yeast is also not out of the woods with regards to refrigeration. It is also vital or more preferable to refrigerate dry yeast in order to get optimum results in your brewing. The last thing you want is beer of inferior quality – especially if it is YOURS!
If you’re still curious about its effects on your brew, why not have a bash? What could be the worst that could go wrong?
