CROSSMYLOOF BREW YEAST

​

​

BELGIAN STRAIN CLASSIFICATION: Suitable for anything Belgian – i.e. a strong & phenol rich blonde, a spicy golden ale, or light or dark abbey ales. Beers fermented with our Belgian have that classic Belgian ale flavour - i.e. hints of clove with distinctive fruity esters and banana character. For a more intense flavour ferment at its higher end.
Saccharomyces cerevisiae. RECOMMENDED TEMPERATURE RANGE: 59 - 82°F (15 - 28°C); ATTENUATION: (77-83%); FLOCCULATION RATE: 70-72%; VIABLE YEAST CELLS: >20 x 109 cells; GMO STATUS: GMO Free; Max brew strength per sachet in a 23 l brew - 9.5% ABV (Double pitch if a higher abv is required) 

​

KöLSCH STRAIN CLASSIFICATION: Kölsch lager ale yeast is a top fermenting lager clone yeast and produces a clean lager aroma without the associated sulphur. This yeast is perfect for most kinds of lager.  Ferment at lower temps for a cleaner taste and extended lagering time will produce a cleaner brew.  2 packs may be required if fermenting below the recommended temperatures. Can’t ferment at 15c?  Room temp will do just fine… COLD AGE FOR 8 WEEKS for best results.
Saccharomyces cerevisiae. RECOMMENDED TEMPERATURE RANGE: 15 - 22°c; ATTENUATION: (75-82%); FLOCCULATION RATE: 76-80%; VIABLE YEAST CELLS: >20 x 109 cells; GMO STATUS: GMO Free; Max brew strength per sachet in a 23 l brew - 9% ABV

​

KRISTALLWEIZEN STRAIN CLASSIFICATION: A top-fermenting wheat beer yeast that ferments clear and imparts hints of banana and clove esters, balanced with spiced aromas. Ferment at the higher end for a more robust flavour. This yeast produces a silky mouthfeel and rich body.
Saccharomyces cerevisiae. RECOMMENDED TEMPERATURE RANGE: 59 - 95°F (15 - 35°C); ATTENUATION: (73-79%); FLOCCULATION RATE: 70-73%; VIABLE YEAST CELLS: >20 x 109 cells; GMO STATUS: GMO Free; Max brew strength per sachet in a 23 l brew - 9% ABV (Double pitch if a higher abv is required) 

​

ALE (CASK) STRAIN CLASSIFICATION:  A top-fermenting ale yeast suitable for a variety of ales. It's primarily a strain that prefers cask conditioning, but it's suitable for all types of ale. For a cleaner finish ferment at the lower temperature end
Saccharomyces cerevisiae. RECOMMENDED TEMPERATURE RANGE: 16 - 25°C; ATTENUATION: (73-82%); FLOCCULATION RATE: 75-78%; VIABLE YEAST CELLS: >20 x 109 cells per gram; GMO STATUS: GMO Free; Max brew strength 9.5%ABV 

​

​

​INSTRUCTIONS: Although Crossmyloof Yeasts don’t require rehydration, cleaner, quicker and more professional results will be produced if rehydrated before use. For all strains add the sachet contents to 100ml of water previously boiled and adjusted to a temperature between 21-25°c.  If fermenting at a lower temp (i.e. using Kolsch at a lower temp), rehydrate using 100 ml of 17-20°C water. Stir gently into a yeast cream, let stand for 15-20 minutes then add yeast cream directly to wort. Alternatively the dry yeast can be added directly to the wort by sprinkling onto the surface and leaving to stand for 10-15 minutes before stirring.  Aerate your wort once the yeast has been pitched for 5 minutes


STORAGE: Store in original packaging at below 50°F (10°C) for optimum 29 month life. At 68°F (20°C) storage temperature viability will remain high for 12 months. At 86°F (30°C) storage temperature viability will remain high for 4 months. Above 86°F (30°C) viability and yeast condition will become seriously compromised within 6 weeks

SOUR3.5 - A LACTIC ACID PRODUCING DRY ACTIVE YEAST FOR ANY SOUR BEER

This yeast strain (Lachancea termotolerans) produces lactic acid while initiating alcoholic fermentation, so perfect for sour beers. SOUR3.5 makes a consistent “crispy” SOUR beer & is compatible with any conventional yeast, making it ideal for any sour-style beer production.

No need for the addition of lactic acid, or kettle souring shortening the brewing processing

How to use: Simply pitch, wait 1 to 4 days until ph reaches 3-3.5 then pitch another standard yeast of your choice to stop the souring process and to continue fermentation.

​

Dosage: 30g per 23l @ 18 to 25c Tolerance: 7.2% ABV

​

KVEIK ALE YEAST - No.1 (Voss) & HORN (Hornindial)

Every 10g pack has enough viable yeast to brew up to 23L (5 Gallons) of your beer and can achieve 12.5% abv. The yeast is a dried yeast.

​

Kveik means yeast in Norwegian and ferments between 25°C & 40°C (77-104°F) with an optimal range of 35-40°C (95-104°F). A fast fermentation is achieved within the optimal temperature range with full attenuation typically achieved within 2-3 days. The flavour is consistent across the entire temperature range. VOSS is semi-neutral with notes of orange & HORN is more tropical in flavour.

​

Fermentation times: - 2-4 days at 40°C (104°F), 3-4 days at 30°C (86°F), 5-7 days at 25°C (77°F)

Medium to high attenuation and high flocculation.

​

Tip. Kveik needs a good dose of yeast nutrient to be added to the wort, more so than regular yeast. If the wort has a low amount of nutrients the Kveik will stress which will in turn produce a level of esters.

​

Tip. If dry hopping bring the temperature down to around 21c to dry hop once the gravity is stable.

Pitching Directions

Pitch the yeast directly on to the surface of the wort at the fermentation temperature (or at a temperature slightly above). Sprinkle well over the wort surface to avoid clumping. Aerate well with a sterilised spoon in a splashing motion for 5 minutes.  

 

Rehydrating

Alternatively, sprinkle the yeast in 100ml of sterile water or boiled wort at 24 to 29°C (75°F to 84°F)*. Leave to rest 15 to 30 minutes, gently stir and pitch the resultant cream into the fermentation vessel. *Hell Pilsner yeast rehydration temp is between 15 to 25°C (59°F to 77°F)

 

Storage

Transportation: The yeast can be transported at room temperature for up to 3 months without affecting its performance. Once you receive it store in cool (< 10°C/50°F), dry conditions.

Shelf Life: Refer to the best before end date printed on the sachet label. Opened sachets must be sealed and stored at 4°C (39°F) and used within 7 days of opening. Do not use damaged sachets.
