I just saw this and have about 1/2 of my Yeti rambler left so I put a dash of salt in. Yes, it does take the bitterness away, but it also doesn't take much salt! No bitterness, but a slight salty taste. I'll try less salt next time.Love my coffee. At least a pot a day.
Just read an article that adding salt to coffee takes the bitterness out. My new thing to do now.
