	Brewing yeast strains from the Alfred Jørgensen Laboratory Largest commercially-available collection of brewing yeasts in the world We can offer you the access to the largest collection of brewing yeasts in the world - 850 yeast strains collected, characterized and carefully preserved over almost 130 years. Our collection includes lager yeast, ale yeast, stout yeast, wheat beer yeast, specialty (Saccharomycodes) yeasts for non-alcoholic and low-alcohol beers, and yeasts for bottle conditioning, including Brettanomyces strains. Our yeasts and how we characterize them To classify the technological properties of our yeast strains for beer, our Alfred Jørgensen Laboratory has developed a coding system in which yeasts are typed according to a 6-digit code (the Alfred Jørgensen Descriptive Code). This provides you with a description of the technological and aromatic properties of each strain. Typing of Alfred Jørgensen culture yeast is carried out by analysing laboratory-scale fermentations. Lab fermentations for two generations are conducted in laboratory tube fermenters Yeast strains are typed according to their technological properties, based on the examination of 25 physical and hedonic fermentation characters under standardized conditions. These include sensory evaluation and optional aroma profiling by Gas Chromatography. From these characteristics, the properties of each brewing yeast strain are succinctly expressed by a 6-digit code. Today, more than 150 brewing yeast strains have been typed according to the 25 physical and hedonic characters and given a 6-digit code. This describes the strains’: 1) Flocculence 2) Reproduction 3) Rate of Attenuation 4) Extent of Attenuation 5) Aromatic Quality (eg level of esters and other aromatic compounds) 6) Cleanness (absence of diacetyl and sulphur compounds) What could a new brewing yeast do for you? Higher yields of alcohol from raw materials Better attenuation control More flocculence / less flocculence Better diacetyl control More sulphury / less sulphury beer Lower beer pH / higher beer pH More esters / less esters More control over brewing yeast load to centrifuge More control over brewing yeast load to filter Get rid of contaminant wild yeasts in your brewing yeast culture Get rid of contaminant bacteria in your brewing yeast culture And more!

The Alfred Jørgensen Laboratory can supply regular quality-assured cultures of your own brewing yeast.

Trusted brewery partners since 1881. All brewery yeast cultures are fully traceable and tracked during shipping. Phytosanitary certificates and other forms of official documentation are also provided for all brewing yeast cultures produced by AJL.

Before dispatching a brewing yeast culture to you we carry out a range of quality assessments, including: checks for foreign contaminants such as wild yeasts and bacteria, checks on yeast colony morphology to assure culture purity, checks on yeast flocculation performance to assure fermentation consistency and checks on DNA composition to assure yeast culture identity.

Our brewery yeast propagation service provides you with yeast when you need it. And it's guaranteed to perform.

We can propagate brewer's yeasts of all types in volumes which range from a few litres to a few hundred litres. Yeast is grown to order from your brewery yeast culture in our laboratories then shipped to your brewery by courier on ice.

We can propagate ale brewery yeast, stout yeast, lager yeast, wheat beer yeast, specialty (Saccharomycodes) yeasts for non-alcoholic and low-alcohol beers, and yeasts for bottle conditioning, including Brettanomyces strains.

All propagated yeast cultures are tested in accordance with our BS EN ISO 9001: 2008 certified quality management system.

Brewers all over the world rely on our confidential safe deposit service to protect and preserve their brewery yeast strains.

Brewery yeast strains, selected for the flavours they give to your beer, and the way they behave in your brewing process, must be looked after if their natural tendency to change is to be countered. Preservation and maintenance of industrial brewing yeast strains is an important job. It needs a high degree of technical skill and the right equipment.

All brewery yeast cultures held by us are stored at -196^oC in liquid nitrogen - one culture in the UK, a second culture in Denmark. All brewing yeast strains are held confidentially for the exclusive use of the brewery or brewery group that deposited them.
