    Any idea why the IBU values are so much higher? It says it is a recipe for 6 gallons. I assumed that was the boil size and I'd end up with about 5 gallons.
    Thanks

    OK, then no worries I guess. I'm new to brewing and it is a little disconcerting that discrepancies like this can occur. Any idea why mismatches occur?

    Than ks

    this site uses your settings in the equipment profile, all stats are based on the settings, brew kettle size, losses also the efficiency for brew house and yeast attenuation, not everyones settings are the same, I set my recipe's at 80% a new brewer will not even get 70 if lucky, big difference and the list goes on
