Made a cold brew over night and it does tone the bitterness down, but its still there sitting right outside of tolerable.
Most people are still going to want to add a sweetener of some kind.
Mixed about 50/50 with an orange pekoe cold brew. Flavor is unsurprisingly diminished, but there is still some of the flavor there. Bitterness is tamed, but still there in the aftertaste.
Might be able to sip it down this way.
