This is the result of my experimentation with the Death Wish Coffee available as a special batch, with adventures enumerated here.

A small run of 750ml bottles is made when I can get a hold of the beans and they tend to go fast. Get 'em while you can.

Now, just to reiterate, while the caffeine content of BBotE is high, I do not know exactly how high and the Death Wish is presumably higher than normal.  I normally recommend keeping consumption below 100ml/day but it's probably prudent to keep it under 50ml/day for Death Wish.  By my rough calculation, you’ve got about the equivalent of a month and half’s worth of caffeination by Starbuck’s Ventis in that bottle.  While you could drink an entire case of Red Bull you picked up at Costco in a day, you probably shouldn’t.  The same wisdom applies to BBotE.  Know your limits and consume accordingly.
