i was so excited to get into this hobby. put my first brew in january 1st. a cherry wheat. i know the hydrometer is the tell-tell sign of fermentation but i couldn't help to be worried and overly concerned since i had no activity whatsoever in the airlock. however, i woke up this morning, 8 days after putting my batch in the primary and i had bubbles. i go to the grocery store and take my son to the park and come back home to beer coming up into the airlock. i was so happy, i thought i was gonna cry. all that noob worrying for nothing.
