Death Wish Coffee Co. and Black Insomnia have been battling back and forth for the title of World’s Strongest Coffee for as long as we’ve been familiar with both brands. The World’s Strongest Nitro Cold Brew title is one that absolutely goes to Death Wish Nitro Brew, however, if for no reason other than the fact that Black Insomnia isn’t making one yet. Sold in 4 packs of 11 ounce cans, Death Wish Nitro Brew combines their signature coffee with a nitrogen infusion to create a rich, creamy coffee with a fair bit of head. The black coffee is made without preservatives and drinks almost like a stout beer except, you know, it’s highly caffeinated coffee designed to kick your ass with a single can. Keep the cans refrigerated and you can have a delicious cup of cold brew whenever you want without having to worry about cleaning a cold brew coffee maker. Just don’t go crazy with the stuff unless you have a cardiologist on speed dial, because it’s dangerously strong.
