I doubled up on my specialty grains(roasted barley and chocolate malt) for what I thought was total of 2.5 lbs. When I got home I realized that my LHBS also doubled up my crystal malt as well and threw it in the same bag as the dark grains. I now have 4.5 lbs. in one bag. Can or should I cold steep all three? I realize I'll probably need around 2 gallons of water to do so.....or should I just repurchase the correct amount of specialty grains in SEPARATE bags! Thanks for any input....Mark
