Wyeast Activator™ 3944 Belgian White Beer yeast

This versatile witbier yeast strain can be used in a variety of Belgian style ales. This strain produces a complex flavor profile dominated by spicy phenolics with low to moderate ester production. It is a great strain choice when you want a delicate clove profile not to be overshadowed by esters. It will ferment fairly dry with a slightly tart finish that compliments the use of oats, malted and unmalted wheat. This strain is a true top cropping yeast requiring full fermenter headspace of 33%.

Instructions for the proper use of Activator™ packages:

1. To activate, locate and move inner packet to a corner. Place this area in palm of one hand and firmly smack package with the other hand to break inner nutrient packet. Confirm inner packet is broken.
2. Shake the package well to release the nutrients.
3. Allow package to incubate and swell for three hours or more at 70-75°F (21-24°C) or immediately direct pitch into wort.
4. Use sanitizing solution to sanitize the package before opening.
5. Shake well, open and pour Activator™ into five gallons of well-aerated or oxygenated wort at 70-75°F (21-24°C). Maintain temperature until fermentation is evident: by CO2 bubble formation, bubbling airlock or foaming on top of wort.
6. Adjust to desired fermentation temperature.

Full swelling of Activator™ packages is not required for their use. The contents of Activator™ packages may be direct-pitched without prior activation. Our smack pack technology is intended to be a tool for your use in determining viability, and in initiating metabolism for faster starts to fermentation.

Swelling of the packs before they are smacked .If the packs warm up, dissolved CO2 in the yeast slurry will come out of solution and cause the pack to swell. It is not going from liquid to a gas state.. the liquid form of CO2 only exists at extremely high pressure or extremely low temperatures.
The swelling DOES NOT indicate that there is an infection or cross contamination

Customer Comment:

First time user of liquid yeast. 2 weeks at a controlled 21C and still thick foam on top. Hopefully it will drop soon.

On 26-May-2016 the supplier responded:
Hello, John

Sorry for the problems, we sell a lot of Wyeast and we store the yeast in our dedicated Wyeast fridge to keep it at its best
We have has some customer who have issues with Wyeast. best advice is on the brew day get it out of the fridge let it warm up to room temperature for 2-3 hours, Then smack the pack, This way the yeast does not go in to shock and die.
Its always as a homebrewer worth having a spare dried yeast just in case.

If its think foam it sounds like an infection
Whyeast generally starts to ferment like normal yeast in a day or 2 any longer and there is an issue with it
