Beer Making
Propagator Packs each contain around 25 billion cells of pure yeast and a smaller inner sachet of yeast nutrient. In order to activate the yeast the inner sachet must be ruptured and the yeast thoroughly mixed with the nutrient by kneading the pouch.
When left in a warm place the yeast will grow and the pouch will expand.
This can take anywhere between two and ten days.The pouch can then be opened and the yeast pitched.
Activator Packs contain a minimum of 100 billion cells in a yeast slurry. The Activator is designed to directly inoculate 5 gallons of standard strength ale wort (1.034-1.060 SG) with professional pitching rates.
For lagers, we recommend inoculating the wort at warm temperatures (20-21°C), waiting for signs of fermentation, and then adjusting to the desired temperature.
Alternatively, for pitching into cold conditions (1-14°C) or higher gravity wort, we recommend increasing this pitching rate.
This can be achieved by pitching additional Activator packages or by making a starter culture.
Propogator packs are being phased out in favour of Activator Packs which have substantially more volume and yet cost only £6.75.
During this phase in period we will seek to replace the Propagator orders for the Activator as stocks allow.

1968 - London ESB
£6.75More information
A highly flocculent top fermenting strain with a rich malty character and balanced fruitiness. This strain is so flocculent that additional aeration and agitation is needed.

2565 - Kölsch
from £5.75More information
True top cropping yeast similar to Alt strains. Produces slightly more fruity/winey characteristics. Fruitiness increases with temperature increase. Low or no detectable diacetyl production. Also ferments well at cold temperatures 13-16° C. Used to produce quick-conditioning pseudo-lager beers. Requires filtration or additional settling time to produce bright beers.
Flocculation: low
Attenuation: 73-77%
Temperature Range: 13-21°C
Alcohol Tolerance: approximately 10% ABV
