I helped a friend brew an Arrogant Bastard clone kit (Brewer's Best Imperial IPA) today. The instructions said it would be OG 1.081-86, but when I punched the ingredients into brewtarget, the calculated OG was more like 1.065. Also, the amount of hopping they recommended was insane, something like 2oz of 14.2% Columbus (which worked out to over 100 IBUs). Is this normal for kits, to be off so wildly?
I have never done a kit--I usually make my own recipes, and got started out of a clone book, so I always had to buy the ingredients I needed severally. In retrospect I guess it might have been a lower volume than a 5 gallon batch, but I reined in their hopping and ended up with fully 2 oz left over. I am looking forward to the batch, but wow, I am not used to kits.
