Patent No. DE2145298A1: Instant Beer Powder

March 22, 2015 By Jay Brooks

Today in 1973, US Patent DE 2145298 A1 was issued, an invention of Siegfried Beissner, for his “Instant Beer Powder — by vacuum-freeze drying.” Here’s the Abstract:

Beer is subjected to vacuum-freeze drying at -10 degrees to -20 degrees C, under a press. of about 0.5 atm. with agitation. Beer can be rapidly restored by treating the powder with water and a source of CO2 (pure CO2 or a mixt. of NAHCO3 and tartaric acid) and/or alcohol. The CO2-source and/or alcohol can be enclosed in capsules made from water-sol. gelatine and packed together with the beer powder.

Given that we’re seeing this type of product in the trade recently, and the anti-alcohol groups have been going apeshit, I would have thought this was a more recent invention. But a version of it was around at least as early as 1973, over forty years ago. I wonder why it took so long for it to make it to market?
