Eddyline Brewing in Buena Vista has cans at Argonaut; Boulder's Crystal Springs has bottles and cans at Mondo Vino; Trinity bottles can be found at Mr. B's; Prost sells growlers to Joy Liquors and a few other spots; Bru has bottles at Boulder Wine and Spirits; and Golden City sometimes has stuff at Mile High Wine and Spirits in Lakewood. That trend is going to increase in 2013 as lower-cost packaging options, like Mobile Canning, increase, and smaller breweries look to get their stuff out there on a limited basis, even as the space for new beers gets more and more crowded. In addition to the breweries named above, look for beer from Lone Tree Brewing, Hall Brewing, Strange Brewing, Backcountry in Frisco, the Bull & Bush, Three Barrel, Grimm Brothers, Big Choice Brewing and others on the occasional shelf around Denver this year. This is in addition to breweries like Renegade, Crooked Stave, River North and Dad & Dude's, which have already carved out niches in the freezers of numerous local liquor stores. 2) Nanobreweries and Microbreweries When Strange Brewing opened in 2010, the first of what would become dozens of small breweries in the Denver metro area, they made everything on a one-barrel system. When Wit's end opened a year and half later, it was with a half-barrel system. Some barstool economists figured that model wouldn't work - that the breweries simply wouldn't be able to make enough beer to pay off loans. But so far, those economists have been wrong. In the meantime, numerous other small breweries have opened, some with smaller and smaller brewing systems and off- or occasional hours. You can expect to see more of that in 2013 as part-time breweries flourish because of the demand for crafty local hangouts in small neighborhoods or towns. Already, three new breweries -- in Boulder, Loveland and Golden -- have opened their doors in 2013; more than fifteen others are on the horizon for the first half of the year up and down the Front Range. Make sure you call for hours first. 3) AC Golden's next big hit Full disclosure: AC Golden is owned wholely and entirely by MillerCoors. But the "crafty" brewery, located deep inside the megabrewer's massive Golden plant, is cranking out fantastic beers on several levels. For small-batch fans, there are the sours, barrel-aged stouts and other flavor-packed brews that rival Colorado's best independent microbrewers. For those looking for the next "approachable beer," AC Golden is also winning - literally - having brought home six Great American Beer Festival medals in the past few years for its lagers. At some point, the parent company is going to notice what a good thing they have going and take one of these beers national, as it did with Blue Moon. When that happens, craft brewers may have a real fight on their hands. 4) Pelletized hops Colorado's hop farming industry is almost entirely supported by AC Golden, the MillerCoors small-batch incubator that makes Colorado Native. But the farmers are adding acreage every year - and adding customers among Colorado's craft breweries. The biggest obstacle for expansion, though, is that Colorado's growers aren't able to form their hops into pellets, which is the primary way that brewers use them. This year, the largest farmer, Misty Mountain Hops in Olathe, sent some of its hops out of state to be pelletized, however, and there is talk among other growers of buying a pelletizing machine in the near future. Seems like a perfect industry for Colorado.
