This past Saturday I brewed a stout using WLP004 (Irish Ale Yeast). On Friday I was preparing to make a starter with the yeast and when I opened the vial about half of it sprayed out all over the place like what happens when you shake up a beer and open it. I put the rest of the vial in the starter (1/2 cup DME boiled in 2 cups of water for 20 min) and put it on my stir plate. It had a good amount of bubbles on it by Saturday afternoon so I pitched it in the wort and stuck it in my ferm chamber. Do you think there was enough yeast in the starter to complete fermentation? And is this something I should expect from all yeast in a vial (the spraying all over the place) and be more careful about shaking it prior to opening the vial?
Thanks.
Thanks.
