Rhett and Link are no strangers to consuming strange foods, but even they weren't ready for this beer.

The YouTubers were guests on That's Odd, Let's Drink It! and took confident chugs of Dogfish Head's Chicha beer, before even being told what was in it.

Within the Peruvian beer was chewed up corn. Yup, in order to brew this beer, humans physically chewed purple maize. The reason being that saliva activates the starch from the corn and turns it into sugar.

Thankfully the beer also includes fresh strawberries and pink peppercorns, giving it a sweet and tart taste.

"Why'd you wait to tell us this," Rhett said with a nervous chuckle.

Their minds were put at ease, though, as the saliva-covered corn is boiled for sterilization.

That's probably not the worst thing the duo has put in their mouths, but it's still cringeworthy.

The next drink was a little less strange, as they had a bourbon barrel-aged vanilla stout. The kicker was that it had an insanely high ABV of 18%.

To finish things off, the duo and host Sam Calagione drank a sour beer with a miracle berry. If you're not familiar with miracle berries, they're like little tablets you put on your tongue, that turn anything you eat, sweet. So you can imagine the effect on the sour beers.

They probably wish they had mixed the miracle berry with the spit beer, but they got through the show unscathed, and will live to drink another day.
