You know what sucks ... LUKEWARM BEER!!!
But fear not, St. Louis Cardinals outfielder Stephen Piscotty says he can save your mouth from sucking down overheated brew ... with a very chill invention.
It's called the Beer Bit -- and Stephen and his brother, Nick, swear it will keep your booze COLD for up to an hour!!!
The guys just launched their own Kickstarter campaign -- and already raised more than $13,000 ... PLUS they even got teammate Yadier Molina to help promote it!!!
Cheers to that.
