PHOENIX -- Growlers are changing and Valley breweries celebrated the best way they know how: with beer.
Prior laws stated that beer growlers could only be crafted from glass. New legislation, however, nixed all that.
Now Arizona beer lovers can leave their favorite breweries with ceramic growlers or steel growlers -- or any other growler made from nonporous, sanitary material.
To celebrate the momentous occasion, various breweries across Arizona kicked off the "Great Growler Fill" at midnight Wednesday, offering cheap growler specials and giveaways to thirsty night owls.
