If you ask brewmaster Paul Krutzfeldt about bottling his beer, prepare to be dismissed.

"Speak of that no more," he said in the "brewer's lounge" of the new Great River Brewery, near the foot of the Arsenal bridge at 332 East Second Street in Davenport.

It's not that Krutzfeldt doesn't want his brews available in stores or bar coolers. It's just that he's a fan of the can.

"Cans are where it's at," he explained. "You have less oxygen tolerances, so the beer won't go bad. No light gets in. And you have a lot more accessibility to take them places - boating, camping. They're more easily recyclable."

He later cites the slogan of the Minnesota-based Surly brewery: "Beer for a glass, from a can."

This is the summary of what Krutzfeldt said is a trend in the suds industry: good beer being delivered in a container that has historically been the marker of bad beer.

He said he's not concerned about the association of cans with bland, watery, mass-produced beer. "What good beer have you had the opportunity to buy in cans?" he asked.

But the can is the wave of the future because of the protection it offers and its portability, Krutzfeldt said: "Cans are becoming king."

Although he said that he expects cans to eventually represent the bulk of his business, for the time being he's filling kegs.

For the sake of argument, let's say that the Promise program will be the panacea for Davenport that its backers claim it will be. People will flood into the city because they've been promised college tuition, vocational training, or (if they're in the military) a homestead grant. Enrollment in the Davenport Community School District will reverse its nearly-two-decade-long trend of decline - thus ensuring a greater amount of state education funding, which is distributed on a per-pupil basis. And the increased aggregate property value will bring new riches to city government and the school district through property taxes, thus allowing them to lower the property-tax rate.

Even if all that is true, the backers of the Davenport Promise have structured the program all wrong.
