Hello 3rd batch I have ever brewed and I was wondering when I should add bourbon barrel chunks to my Russian Imperial stout? I have had the chunks soaking in Knob Creek for 2 weeks now and the stout is going to be in my primary fermenter for about 4 weeks or more. Really depends on how the yeast and the wort get along. Not sure if I should add the chunks to the primary fermenter or secondary fermenter.
