I attempted to make a Brewers Best American Pale Ale extract kit, OG was to be between 1.051-1.055 but it ended up as 1.039, after looking into why this was off so much, I see that I topped the water off to the top notch of the 6.5 gallon big mouth bubbler, indicating that this might be 6 gallons of brew and not 5.
The estimated FG was to be 5.0-5.5, but it looks like it's going to be around 3.8%, this brings several questions...
Is there anything that can be done to correct this?
Will there be enough head space to ferment? It looks like there should be.
What's the worst case/best case scenario?
