Carefully place the keg into the ice bath 4 Select Continue and the Zymatic will resume with the chill cycle 5 Monitor the ice bath as the keg will quickly melt the ice as it chills 6 The temperature will continue to be monitored by the Zymatic as it chills to the pitching temperature selected by the recipe 7 When the temperature reaches pitching temperature the wort will continue to circulate for 10 minutes to ensure all the wort is at the same temperature in the keg 8 After the chill cycle is complete the Zymatic will drain the remainder of the wort in the step filter into the keg 9 When the brew is complete it will return to the menu Disconnect the ball locks from the keg There are many methods that could be used to chill your wort a copper coil chiller sticking the keg in a freezer leaving overnight or stirring the wort while in an ice bath We encourage you to find the method that best suits you Pitch Yeast There are two different kinds of yeast that are sold dry and liquid Either type of yeast can be used to ferment your wort If you are using liquid yeast make sure to take it out of refrigeration when you start your brew to give the yeast time to warm up Dry yeast does not require any preparation although some brewers prefer to proof their yeast 1 After your wort is sufficiently chilled remove the foam trap from the Keg Seal remove the Keg Seal and pour in your yeast Your ke
