hello every body.
I brew my first mexian cerveza kit and I drank it. Now I`m brewing lager. I did my wort with coopers australian lager and enhancer and i used little bit brewing sugar. When I woke up in the morning my wirt rose and went out side of fermenter in the air lock. So now I`m wondering do I have to add some more yeast to my wort. because some of them went out.
