Hi everyone, yesterday I did my first all grain - a Founders Breakfast clone. When I went to pitch my yeast, WLP001 , I lost about 1/2 a vial to it exploding like a shaken beer can on open. I do have a small bit of krausen in the fermenter this afternoon but the is not a whole lot of airlock activity. My question is is the amt of yeast used enough for a 5 gallon batch to get full fermentation to FG or should I add some from a starter in the next day or two to give it an extra push?
