My buddy just got himself a brew-magic system and we are currently on our 3rd brew and we want to go big.
Right now we are looking at brewing up a 5.5 gallon batch of wheat wine with an OG of 1.092. I have never brewed anything this big before - the grain bill alone is 19 lb (with 1 lb of table sugar to be added during primary, bringing the OG to 1.100). The efficiency is set to 70%. The previous few brews have yielded efficiencies in the 80's (though they were of much lower OGs). The mash tun has more than enough room to fit the grains and water needed (its a converted keg)
I'm just curious how I should go about hitting the desired OG - I would really like to make 5.5 gallons (or more), but I def wouldn't want to make less than 5 gallons. I don't mind sparging with more water and boiling longer - I'm just not sure how to go about calculating that. I do have a refractometer to take quick readings of the run off if needed.
Any help would be greatly appreciated!
