I had a question concerning making a high gravity beer. I'm planning on brewing a high gravity wheat beer and I am using Coopers 1.7kg hopped wheat malt extract. Apparently it's labelled at 200 IBU. I've previously read the posts about Coopers extracts and how the IBU # is the amount over 22-23 litres of beer. My question concerns using that hopped extract for approximately a 2-2.1 gallons batch (roughly 8 litres). I plan to do this to up the alcohol % to about 7-7.5%. I'm figuring that the IBU will be through the roof if I do so. I've estimated 38 IBU for the batch; is this approximately correct?
also, what could I do to counteract the bitterness? Would adding a ton of sugar help? I figured I'll try buying unhopped extract next time but bought this one because I didn't have unhopped wheat extract available to me from where I live.
