The "Jewish Connection" to the Hexagrams on the breweries and taverns of Germany

Dr. J.J. Hirsh in his article The Hexagram (The Shekel, vol. 14, no. 3, 1981) mentions that "Were it not for the Encyclopedia of   Freemasonry, the "Jewish Connection" to the Hexagrams on the breweries and taverns of Germany would   have never surfaced. The last paragraph under Seal of Solomon states": 

"Among the old Kabbalistic Hebrews, the Seal of Solomon was, as a talisman, of course deemed to be a sure preventive against the danger of fire. The more modem Jews, still believing in its talismanic virtues, placed it as a safeguard on their houses and on their breweries, because they were especially liable to the danger of fire. The common people, seeing this figure affixed always to Jewish brew-houses, mistook it for a sign, and in time, in Upper Germany, the hexagon, or Seal of Solomon, was adopted by German innkeepers as the sign of a beer-house, just as the chequers have been adopted in England, though with a different history, as the sign of a tavern".
