10. Heineken

Percentage of country volume: 2%

Dutch brewer Heineken's namesake beer is slotted into the last place on the top 10 biggest beers in the US. However, the beer giant is also dabbling in some unexpected brews.

In August, Lagunitas, Heineken's California beer label, debuted a nonalcoholic beverage made with THC, called Hi-Fi Hops. The $8 drink is available in a handful of marijuana dispensaries in California, where the drug is legal.

9. Michelob

Percentage of country volume: 3%

Michelob has been on a roll recently, with Michelob Ultra gaining more market share than any other AB InBev beer for the last 13 quarters.

According to executives, Michelob Ultra has managed to tap into Americans' taste for more premium beers — one of the fastest categories in the industry. Super-premium beer has grown at a compound annual growth rate of 8.4% over the last five years, while mainstream beer has dropped by 0.6% in the same period.

8. Modelo

Percentage of country volume: 4%

Modelo is one of several Mexican beers that have been thriving in recent years as iconic American brands have struggled. According to Bank of America and Merril Lynch, Mexican beers accounted for 64% of beer imports in 2017, up from 46% in 2007.

7. Natural

Percentage of country volume: 4%

Natural, best known for its college favorite "Natty Light," is the No. 7 beer in the US despite some rough reviews. RateBeer.com has actually dubbed the drink the worst beer in the world based on drinkers' reviews.

6. Corona

Percentage of country volume: 5%

Corona is another Mexican beer that is having a big impact on the US beer market. Constellation Brands, which imports, markets, and distributes Corona in the US, reported that beer sales grew

4. Miller Light

Percentage of country volume: 7%

3. Budweiser

Percentage of country volume: 8%

Budweiser has struggled to grow sales in the US in recent years. Anheuser-Busch InBev sales dropped by 3.1% in the second quarter, as both Bud Light and Budweiser failed to grow market share.

Problems with Budweiser has AB InBev turning to nonalcoholic beverages. Currently, alcohol-free drinks make up roughly 10% of the company's volumes, with plans to grow that figure to 20% by 2025.

2. Coors

Percentage of country volume: 9%

MillerCoors is in crisis mode as the brewer scrambles to boost Coors Light sales. Earlier in September, the brewer announced it was restructuring, eliminating roughly 350 salaried positions across the company.

"We are moving quickly and decisively to get our business back on track," MillerCoors CEO Gavin Hattersley said in an email to distributors, according to a news report on the company's website.

1. Bud Light

Percentage of country volume: 18%

Bud Light is by far the biggest beer in the US. However, the bigger the brand, the farther it has to fall.

AB InBev managed to build buzz around the brand with the viral "Dilly Dilly" campaign. However, the fact remains that Bud Light has been losing market share for years. It may still be on top, but if the trend continues, it can't stay there forever. As millennials ditch the brew for wine or nonalcoholic drinks, problems may arise for the $155 billion AB InBev.
