Based on boiling 6.50 gallonsliters at 1.049 for 60 minutes, this will decrease your wort by 1.00 gallonsliters, bringing your after boil OG to 1.057. You wanted an OG of 1.062. It looks like it will be under.
Very good, light tasting beer, a lot like a Vienna Lager. Best beer I've made yet. Used bottled spring water, no off flavors. Wife really liked it. 5 gallons only lasted 3 weeks.
