Your liquid yeast must be refrigerated. Please see the temperature scale below, but in general the closer to 0°C the better. Warmer temperatures will lead to a decrease in viability and a greater chance of pressure build up in your pouch(es).
4°C+ Not Recommended
All of our Imperial Yeast Pitch-Right pouches are guaranteed to be viable for 3 months from the manufacturing date printed on the pouch. Because Imperial Yeast package 200 Billion cells in each pouch, the actual shelf life of the Pitch Right pouches may be much longer
Absolutely, making sure that you adequately create/oxygenate your wort will help to ensure that you give your yeast the best possible conditions to get started fermenting your wort and turning it into delicious beer. Adequate oxygenation will also help to minimise certain off-flavours, and reduce the possibility of a stuck fermentation.
The Pitch-Right pouches were designed to give home-brewers enough yeast to directly pitch into 19 litres of wort. If the volume of the wort exceeds 19 litres or the original gravity of the wort is higher than 1.070 (17°P) more yeast may be required.
Because there is so much yeast in each Pitch Right pouch, Imperial Yeast do not recommend making starters smaller than 4 litres without a stir plate, or 2 litres with a stir plate. This will give you about the same amount of yeast contained in two Pitch Right pouches.
We recommend not using the yeast if it has been frozen. That said, slowly thaw the pouch in a refrigerated environment, once the pouch is thawed it will be ready to pitch. Imperial Yeast's internal testing has concluded that you can expect around a 20-30% viability decrease if the pouch has been frozen.
at the moment, in order to offer affordable shipping to our customer, we have set an order limit of two pouches, If you would like to order more than two pouches, please reach out to us, and we will do everything that we can to fulfil your order.
