Patent No. 1015443A: Apparatus For Macerating Wort

patent-logo
Today in 1912, US Patent 1015443 A was issued, an invention of Robert Hoffmann, for his “Apparatus for Macerating Wort.” There’s no Abstract, but in the description he explains the problem and his solution:

In macerating they wort in making beer the sparging water has hitherto been poured on to the wort by means of a rotary sprayer spraying over or sparging the wort. As the sparging water falls from a certain height on to the surface of the wort it is not only impossible to avoid unintentionally mixing the wort with the sparging water,’but the latter is also undesirably cooled. Both disadvantages thus involve a loss of yield from the grain and thus mean an incomplete’ working.

Now as compared with the ordinary apparatus for maceration this invention consists in the sparging water not being, allowed to fall from a height on to the surface of the wort but being introduced in layers on to the surface of the wort, so that the grain during maceration is slowly compressed by the sparging water and does not mix therewith.

This improved apparatus consists in other’ words in the sparging water being allowed to flow on to the wort in a continuous stream without first having to fall through the air — on to the surface of the wort.

Beer Birthday: Sabine Weyermann

weyermann-logo
Today is the 56th birthday of Sabine Weyermann, co-owner of Weyermann Malting in Bamberg, Germany. If you’ve visited any of the Craft Brewers Conferences, you’ve no doubt seen the bright yellow and red of the specialty malting company, which is sold in the U.S. by the Brewers Supply Group. Sabine’s family began the Weyermann Malt company in 1879, although she can trace her family back at least as far as 1510. She’s an amazing person, and her malt has helped fuel many a small and large brewery. Join me in wishing Sabine a very happy birthday.

Beer In Film #51: Malting Barley, The Malting Process

brookston-film
Today’s beer video is a nice overview of the malting process by which raw barley is turned into brewing malt to make beer. Malting Barley — Malting Process walks you through the malting steps. It was created by the Malt Academy, which is part of the “Canadian Malting Barley Technical Centre, a non-profit, independent organization that was set up to provide technical assistance to the malting barley and brewing industries.” If you want to see more or go father in depth, they have even more videos on YouTube.

Trouble Brewing: Changes In FDA Rules For Spent Grain

barley
There was an interesting article recently on Craft Beer Business detailing how changes to the FDA regulations regarding spent grain might effect breweries. Under a proposed new “definition, craft breweries would be labeled animal feed manufacturers and be regulated as such by the FDA.” Given that most breweries have to find something to do with their spent grain, whether selling it or donating it, if the proposed rules take effect, it will undoubtedly alter the way breweries dispose of their grain. Check out the article, FDA rule regulates spent grain sold as animal feed, to see the rule changes.

Beer In Ads #983: The Goodness Of Malt In Fondue


Tuesday’s ad is for the Barley and Malt Institute, from 1959. This is the fourth ad I have from the now defunct trade group for barley growers. In this one a feminine hand is adding beer to a fondue pot, while a man is stirring it and holding up the “OK” sign, presumably to indicate there’s enough beer in the mix. And that tagline, “Fun-Flavors your creative cookery;” I’m not even sure that quite makes sense. But cheese and beer? Now those are some fun flavors.
