Bottoms up, beer fans. It's time again to cast a ballot in the Des Moines Registers's Beer Brackets. 

Sixty-four Iowa craft beers face off in the win-or-go-home, six-round tournament until one champion beer remains. The best part? You vote daily to decide which beer wins.

How to vote 

Head to DesMoinesRegister.com/BeerBrackets, select the beer you want to see win in each matchup, click vote and head to the next matchup. The round of 64 runs until March 11, when the round of 32 kicks off. Each new round launches at 8 a.m.

What you need to know this year 

  • Vote once — and only once — each day: Participants can cast one ballot daily per electronic device. Yes, that means you can vote once a day from your computer, smartphone and tablet. The Register may remove votes if it determines they were cast in an effort to circumvent the one-daily-vote-per-device restriction.
  • Prizes: Enter at DesMoinesRegister.com/BeerBrackets for a chance to win a $100 gift card from El Bait Shop, $50 from Exile Brewing or $25 from Reclaimed Rails Brewing. Each winner scores bonus merchandise from Brew Moines, the metro's favorite craft beer mobile app. Enter by March 21 to be qualified to win. Must be age 21+ to enter.
  • When's each round? The round of 32 kicks off March 11, with the round of 16 launching March 14. The round of eight kicks off March 18, with the round of four starting March 21. The finals kick off March 25 and a 2019 winner will be crowned March 27.
