(CNN) — It used to be as plain as a beer-foam mustache. Portland, Oregon, has more breweries and brewpubs than any other place -- in the sixties now -- ergo, it's the world's greatest beer city. And none of those breweries makes swill.

But the world is changing for the better -- and catching up to a movement pioneered by Portlanders.

Craft beer is worldwide now and other cities nip at our Birkenshod heels in the crucial best-beer-city-in-the-world race.

Denver and San Diego are contenders without a doubt. Milwaukee. Brooklyn.

Various Asian capitals -- Beijing, Singapore, Tokyo -- all have thriving beer scenes.

Berlin, where Stone Brewing is building a big beer hall and brewery. England, where craft breweries are sprouting even as traditional Brit pubs close weekly.

Prague, of course, where golden lager was born. Dublin indubitably.

Even Asheville, North Carolina, which rather noisily voted itself Beer City USA a few years back, is now in the running for real with an impressive roster of local breweries and big new production breweries built by New Belgium, Oskar Blues and Sierra Nevada.

Bless 'em all, for the rising tide of craft beer floats all boats, and we Portlanders welcome the company. As long as all acknowledge that there's just one best beer city in the world: Portland, aka Beervana.

Here are 23 reasons, a number you'll recognize as a prime, of which there are an infinite number.

Which is really big. Almost like being the best beer city in the world.

1. According to supermarket tracking services, Portland leads the United States in percentage of craft beer sales with nearly 40% of beer purchases being craft beer.

2. Oregon breweries brewed 53% of all the draft beer served in the state.

3. We keep finding new places to serve beer, such as growler-fill stations, which have opened in major grocery stores, as stand-alone establishments and in a Southeast Portland mini-mart that anywhere else would sell fried chicken and half-racks of Milwaukee's Best.

4. Speaking of growlers (large, re-fillable bottles that allow you to take large amounts of freshly tapped beer to go), the Portland-designed, Steampunk-styled uKeg keeps beer cold and carbonated and people love the idea: Speaking of growlers (large, re-fillable bottles that allow you to take large amounts of freshly tapped beer to go), the Portland-designed, Steampunk-styled Growlerwerks LLC hoped to raise $75,000 in its Kickstarter campaign and so far nearly 5,000 people have donated $665,000 -- with about three weeks to go.

5. It's hard to imagine the critical mass of more than 60 brewing establishments in a town.

7. We have the biggest outdoor beer party on the continent, July's We have the, July's Oregon Brewers Festival , which attracts more than 85,000 people a year -- many of whom are out-of-state or international beer tourists -- to its five-day run at Tom McCall Waterfront Park.

8. Missed the OBF? No problem. Beer festivals happen year' round in Beervana, such as Missed the OBF? No problem., such as December's Holiday Ale Festival , when thousands of big-beer fans drink can't-find-'em-anywhere-else winter beers in big, heated tents in Portland's Pioneer Courthouse Square.

There are beer events every week of the year thanks to great bottle shops such as Belmont Station , BeerMongers, By The Bottle, Imperial Bottle Shop and Taproom and others that organize a couple hundred beer releases, meet-the-brewer events, tap takeovers and the like every year.

There are also brewers dinners, beer tastings and Roscoe's monthly beer summits.

Nobody's done a festival count, but Portland hosts a couple of hundred a year, including specialized events such as an organic beer festival, a fruit beer festival, Peche Fest (only peach beers and ciders on tap) and Biketobeer Fest

13. In 2010 Mike Wright opened a one-barrel nanobrewery called Beetje in his Southeast Portland garage.

In late 2011 he took the plunge and opened The Commons Brewery in a commercial space with employees, a tasting room and a seven-barrel system brewing farmhouse ales.

At the end of this year, he's moving to a space three times as big and adding a 15-barrel brewhouse.

Who says you have to brew an IPA to make it in this town?

14. But it doesn't hurt: IPA is the beer that made Portland an IPA town 20 years ago, and is still a great beer and the brewery's flagship, though its 60- bitterness units of hoppiness is a modest number these days.
