I'm currently working on my third batch of home brew so I'm still a bit new to this.
I used a chocolate porter kit, but I doubled the cocoa powder, added peanut butter powder, and 1lb of oats. Thus resulted in an OG of 1.075 when it was supposed to be about 1.051. I used Wyeast 1338 European Ale. I put the yeast in when the fluid was 67.5°... there are small bubbles in the air lock, but I don't see active bubbling about 24 hours later. Should I worry?
