| One of SPL's core strengths is the ability to develop and manufacture our own dried yeast strains available for supply in either bulk or sachets to both the home brew and commercial drinks sectors.
Drawing on a wealth of knowledge, expertise and state of the art facilities we have the capabilities to develop and isolate new strains, then through correct propagation and drying methods has allowed us and continues to allow us to bring NEW strains to the commercial and home brew drinks sectors. Our yeast strains are used in the production of spirits, liqueurs, beers, ciders, wines, alco bases and a significant number of other flavoured and un-flavoured alcoholic beverages.
SPL supply there core yeast strains, nutrition, carbons and spirit flavourings to the commercial alcoholic drinks industry and are responsible for a variety of market leading and award winning brands around the world.
One yeast cell is invisible to the naked eye, measuring about 1/100th of a millimetre. Most people can resolve down to 1/10th of a millimetre so the yeast cell is `ten times too small` to see. One gram of SPL yeast will contain 10,000 MILLION living yeast cells (expressed as 1 x 1010 CFU/gram).
There are many thousands of different strains of yeast, but only a small number of these strains are suitable for the fermentation of pure sugar into alcohol. Since 1992 SPL have carried out in excess of 10,000 individual fermentations as part of an on going screening program to identify the `best` alcohol yeast strains for the fermentation of pure sugar into alcohol.
In addition to the ongoing yeast strain screening program, SPL is actively working with leading Universities in the United Kingdom looking for further improvements within the areas of temperature tolerance, yield (grams ethanol per kg of sugar), fermentable ethanol ceiling & tolerance, alcohol purity and rate of fermentation. The most significant projects have been;
