As his answer to reducing the environmental impact of excess packaging and the need to reach for a cold one as a reward for summiting a mountain or padding across a lake, an entrepreneur out of Alaska has created a 'just-add-water' beer concentrate for outdoor lovers.

Patrick Tatera of Pat's Backcountry Beverages has created a concentrated beer formula that can be turned into a tall frothing pint on a mountain peak or lakeside with the addition of water and the use of a carbonator.

It's a concept that tries to spare campers and hikers from having to lug cans of brewsky in their backpacks and yet provide parched outdoor lovers with a sudsy refreshment in the wilderness.

The company also sells portable carbonators.

In its concentrated form the beer has a high percentage of alcohol akin to vodka or whiskey but it is diluted with the addition of water and the carbonation process.

The formula is made with a “hybrid brewing technology' and a patent-pending fermentation process.

The beer concentrate is expected to be available mid-September, with a potential roster of international distributors.

The four-pack Pale Ale and the Black IPA will be sold for $9.95 USD. Each pouch makes one 16oz beer.

Meanwhile, outdoor experts at Outsideonline.com have come up with a gallery of the best outdoor-inspired cans of beer for 2013, including the best post-surf brew and beer for barbecues.
