I am going to be brewing an all grain Peat Smoked Porter for the first time in the next couple of weeks. It's a recipe I found and tweaked a little that hopefully will be great for Christmas.
I find WD40 works very well with any stubborn label. I soak in hot water to get rid of most of the label or what I can then loosen what is left with WD40. Never found one yet that this does not work with.
Where I purchase my ingredients from has three grades if you like of crystal malt. They are listed as crystal malt, light crystal malt & dark crystal malt. I just use the one listed as crystal malt with an EBC of 152 unless a recipe specifically asks for light or dark.
