#115/135 There She Gose Again

This is a great beer published in BYO, by Justin
Fal Allen's Book on Brewing Gose

Issue: May/Jun 2011

Gose is a top-fermented beer that originated in Goslar, Germany. It is brewed with at least 50% of the grain bill being malted wheat.

Dominant flavours in Gose include a lemon tartness, a herbal characteristic, and a strong saltiness (the result of either local water sources or added salt). Gose beers typically do not have prominent hop bitterness, flavours, or aroma. The beers typically have a moderate alcohol content of 4 to 5% ABV.

Because of the use of coriander and salt, Gose does not comply with the Reinheitsgebot. It is allowed an exemption on the grounds of being a regional specialty. It acquires its characteristic sourness through inoculation with lactic acid bacteria after the boil.

Gose belongs to the same family of sour wheat beers which were once brewed across Northern Germany and the Low Countries. Other beers of this family are Belgian Witbier, Berliner Weisse, Broyhan, Grätzer.

Gose was delivered, still fermenting quite vigorously, in barrels to the Schänke. It was stored in the cellar with the tap bung closed but the shive hole left open, so that the still-active yeast could escape. Only when the fermentation had slowed to a point where no yeast was emerging from the shive hole, was the Gose ready to bottle. The barrel was emptied into a tank, from whence it was filled into the characteristic long-necked bottles. These were not closed with a cap or cork, but with a plug of yeast (Flor) which naturally rose up the neck as the secondary fermentation continued.

16th Century Gose was first brewed in the early 16th century in the town of Goslar, from which its name derives. It became so popular in Leipzig that local breweries started to make it themselves.
1800sGose was considered to be the local style of Leipzig and there were countless Gosenschänke in the city.
1939Rittergutsbrauerei Döllnitz was the last brewery producing Gose
1945Gose disappeared with the closing of the brwery
1949Gose reappears when the tiny Friedrich Wurzler Brauerei opened at Arthur-Hoffmann-Straße 94 in Leipzig. Friedrich Wurzler had worked at the Döllnitzer Rittergutsbrauerei and was the only person who knew the secret of brewing Gose.
1950sWurzler handed on the secret recipe to his stepson, Guido Pfnister
1966Pfnister died and the brewery closed and Gose disappeared again
1985Lothar Goldhahn, who was restoring a former Gosenschenke, Ohne Bedenken, decided that it was only fitting that the revived pub should sell Gose. After quizzing drinkers to ascertain its precise characteristics, Goldhahn began to search for a brewery to produce his Gose. None of the local breweries were keen on making such an odd beer, so eventually he chose the Schultheiss Berliner-Weisse-Brauerei on Schönhauser Allee in East Berlin. The first test brews were made in 1985 and production started in 1986.[1]
1988Gose disappeared again
