Super Wager For The Super Bowl

By

sb-50
You knew it had to happen. There’s at least one every year. Two breweries in the home city or state make a bet for whose team will win the big game, with the other’s beer as the prize. The only question is which breweries would step up.

This year, Denver’s Spangalang Brewery is throwing down the gauntlet, and Fullsteam Brewery of Durham, North Carolina has picked it up. The two breweries have wagered the outcome of next weekend’s Super Bowl on february 5, and apparently “the terms of the wager are significant for the brewers and their fans.”

According to the press release I got today from Denver beer writer Marty Jones, “The losing brewery will have to brew a special batch of beer from a recipe chosen by the winning brewery. The beer recipe will include indigenous ingredients from the winner’s state and will be named by the winning brewery.

On tapping day the losing brewery must hang the winning team’s flag and fly it for one week or until the beer is gone, whichever comes first.”

“That Panthers flag,” says Sean Lilly Wilson, founder of Fullsteam Brewery, “is going to look great hanging in the Spangalang tasting room. But we’ll send a beer recipe with some choice Carolina ingredients and flavor to help ease the pain of Denver’s loss.”

“It will be interesting to see if Cam Newtown can sport his 1000-watt smile with Von Miller in his face,” says Spangalang co-founder and brewer Darren Boyd. “I’m thinking ‘Cam’s Kryptonite’ would be a good name for the beer recipe we send to North Carolina.”

Each brewery will be asking its social media followers to suggest beer styles, local ingredients and names for the winning beers.

From the press release:

On February 5, the Friday before the Super Bowl, each brewery will release a special pre-game beer to rally local fans.

Spangalang will bring back Orange Crushsicle, which it debuted prior to the Broncos defeating the New England Patriots to win the AFC crown and a place in the Super Bowl. The beer equivalent of the Dreamsicle frozen treat, Orange Crushscicle is a citrus session ale enhanced with orange juice, sweet and bitter orange peel and vanilla. Its name pays tribute to the past and current defense of the Broncos and predicted the creaming of the Patriots by the Broncos.

“Broncos fans came out in droves to try the beer last weekend,” says Spangalang brewer and co-founder Taylor Rees. “Our tap room will be a sea of orange jerseys when we tap it again.” Fullsteam will release Bless Their Heart, a twist to its recent collaboration with Charlotte-based Free Range Brewing. The beer is made with foraged juniper, North Carolina Frasier fir, and an addition of chokeberry syrup. “We thought chokeberry would be a good ingredient to use in this beer,” Wilson says, “due to Manning’s history of choking in the Super Bowl.” No matter which team wins the game, the rival brewers are comfortable with the wager. “The worst that can happen,” Boyd says, “is we let a like-minded, quality obsessed craft brewer take the lead on a beer of ours. So this is a good bet to make. Although the Panthers flag in our brewery would make us all sick.”

Founded in 2010, Fullsteam Brewery is a Durham, North Carolina production brewery and tavern inspired by the food and farm traditions of the South. The brewery aims to “pioneer the art of distinctly Southern beer” and specializes in traditional and experimental beers with a Southern sensibility. Its beers often incorporate locally farmed goods, heirloom grains, and seasonal botanicals.

Spangalang Brewery was founded in April 2015 by former Great Divide Brewery brewers Taylor Rees, Austin Wiley and Darren Boyd. The brewery crafts world-class beer for locals and celebrates the past and present culture of its historic Five Points neighborhood. Spangalang earned numerous “best new brewery of 2015” honors and a gold medal at the 2015 Great American Beer Festival medal.

May the best brewery win.

Patent No. 810745A: Method Of Pasteurizing Beer

By

patent-logo
Today in 1906, US Patent 810745 A was issued, an invention of Hugo Gronwald, for his “Method of Pasteurizing Beer.” There’s no Abstract, although in the description it includes this summary:

I have invented a new and Improved Method of Pasteurizing Beer in Barrels, of which the following is a full, clear, and exact description.

The hitherto-known method of pasteurizing beer in the barrels in which it is to be transported had the disadvantage that when the barrels were provided with a separate expansion-chamber the natural carbonic acid contained in the beer was`partly lost and the germs or barm at times contained in this chamber could not be killed, so that the beer frequently overflowing into this chamber was not entirely free from germs, while when the necessary space for expansion was provided by not filling the barrel complete y it had to be filled up with beer from another source. These disadvantages are removed according to my improved method by dividing the quantity of beer required for completely filling the barrel between two connected vessels-namely, a lower detachable vessel, hereinafter called receiver, equal in capacity to the required space for expansion and a barrel communicating with and arranged above this vessel in such a manner that the receiver is completely filled, while in .the barrel an empty expansion-space is left equal to the capacity of’ the receiver. The beer is then pasteurized in the barrel and receiver and cooled in the usual way, after which the carbonic acid disengaged during the pasteurizing and which as risen into the. expansion-space in the barrel can be returned Without loss to the beer-‘for instance, by shaking the barrel. T he pasteurizing apparatus being then turned upside down, the beer runs into the barrel from the receiver, while the excess of carbonic acid mounts into the receiver, so that by this simple exchange of the contents of the vessels a filling up of the beer-barrel from another source is rendered unnecessary and loss of carbonic acid is avoided.

Various apparatus or plant may be used for carrying out my said method, provided the barrel and receiver are connected into a combined apparatus.

Patent No. 270844A: Beer-Cooler

By

patent-logo
Today in 1883, US Patent 270844 A was issued, an invention of Friedrich Richter, for his “Beer-Cooler.” There’s no Abstract, although in the description it includes this summary:

My invention relates to beer-coolers, and will be fully described hereinafter.

Heretofore with coolers constructed according. to the plan in general use the ends of the pipes through which the cooling-liquid passes have been united by means of elbows, and as the beer or other liquid to be cooled had to be poured into pans or troughs at the top to flow through perforations in said troughs down over and around the pipes to a pan at the bottom of the cooler, that it might be deprived of its heat in this passage, it has been found difficult to keep the pipes clean, owing to their many elbows, and hence my invention, the object of which is to simplify the connections be tween the pipes, dispenses with the elbows altogether and presents a solid, smooth surface at each end of the beer-cooler, and at the same time unites the parts by such connections as will .admit of the cooler being easily taken apart when it is to be cleaned or repaired.

Another object of my invention is to provide a means for controlling the flow of the cooling-fluid, all as will be fully set forth farther on.

Patent No. 5079927A: Beer Cooling Apparatus

By

patent-logo
Today in 1992, US Patent 5079927 A was issued, an invention of A. J. Rodino and James R. Kinkaide, for their “Beer Cooling Apparatus.” Here’s the Abstract:

A method and apparatus is provided for dispensing beer from a keg without excess foaming wherein the keg and beer temperatures and fluid pressures are controlled such that beer is dispensed at predetermined temperatures at substantially atmospheric pressures even over a wide range of atmospheric temperatures. Beer is supplied under pressure from the keg to a constricted flow line which abruptly decreases flow pressure. A portion of the constricted flow line is immersed in a refrigerating bath to reduce beer temperature. The length of the constricted flow line to the dispensing nozzle is sufficient long and its internal diameter sufficiently smooth that beer flow therethrough is stabilized to significantly reduce turbulence. Beer pressure drop through the nozzle is minimal and beer flow is relatively laminar.

The portion of the constricted line immersed in the refrigerating bath is formed from coiled tubing. The bath fluid is recirculated and the bath temperature is sufficiently low as to cause ice to form. The constricted line has a constant internal diameter throughout its length, and the dispensing nozzle has that same internal diameter. A portable embodiment includes a wheeled trailer for supporting and sheltering the keg.

Patent No. EP0208450A2: Beer Filtration

By

patent-logo
Today in 1987, US Patent EP 0208450 A2 was issued, an invention of Ronald Shackleton, for his “Beer Filtration.” Here’s the Abstract:

It has been proposed to filter beer or tank bottoms using crossflow filtration. In accordance with the invention, this crossflow filtration is achieved using ceramic membranes. In a particular form shown in figure 1, a two stage filtration process combines the functions of clarification and recovery from tank bottoms. Beer is drawn from a tank 1 by a centrifugal pump 2 to a primary filtration stage comprising a circuit in- cludinga a circulating centrifugal pump 3, a ceramic membrane filter 4 and a cooler 5. A proportion of the circulating liquid is drawn off by a positive pump 8, and passed to a secondary filtration stage, again comprising a circuit including a circulating positive pump 9, a ceramic membrane filter 11 and a cooler 12. A proportion of the retentate is drawn off via a line 14. This retentate is of a pasty consistency and normally has a commercial value, in that it is free of kieselguhr or other filter aid.
