I did my first brew (all grain), some things were complicated to achieve and finished at 4 o'clock in the morning because I decided to start at 10 pm (big mistake).
At the end of it all, after I sanitize equipment and put the wort in the fermenter bucket, I sealed and placed the arilock.
Only to realize that I did not put water in the airlock after only seven days of fermentation!
What can I do now? A second fermentation? Set everything out and redo my beer?
The airlock ("S" type) that I use is this: http://ebrew.com/Products_A/airlock_s-type.jpg
