The craft beer industry may be a hotbed of innovation, but one beer continues to reign supreme above them all in an annual poll among homebrewers.

For the seventh year in row, Russian River Brewing Co.'s Pliny The Elder has taken the top spot in Zymurgy magazine's vote of best commercial beers. Pliny the Elder is a Double IPA with alcohol by volume of 8 percent.

"I say it every year, but we really are honored and humbled. There are so many great beers out there," Vinnie Cilurzo, co-founder and brewmaster of Russian River, told the American Homebrewer's Association, which publishers the magazine.

Zymurgy asked AHA members to vote for up to 20 of their favorite beers among any commercial beer available for sale in the Unites States. More than 19,000 votes were received for almost 6,000 different beers and from 1,763 breweries in the online poll.

While Russian River continued to rule in the top spot, Michigan-based Bell's Brewery was the only brewery to place two beers in the top 10: Two Hearted Ale at No. 2 and Hopslam Ale at No. 7.

Though much of the top 10 stayed the same as in 2014, Three Floyds Brewing Co.'s Zombie Dust (No. 8) and Firestone Walker Brewing Co.'s Wookey Jack (No. 10) were new entrants to the top 10 this year.
