Takk fyrir þetta, fínt að fá input til að bæta í fróðleikinn hjá manni. Ég hef ekki séð þessar afleiðingar enn
og er þetta þeim mun áhugaverðara að spá í. Við Íslendingar erum afskaplega heppnir með vatnið okkar en
þeim mun erfiðara að skapa ákveðin einkenni án þess að bæta aukaefnum í. Dæmi var einmitt saltbjórinn
sem Sigurður kom með á síðasta fund sem ættur var frá Þýskalandi minnir mig. Þar var þetta einkennið á
þeim bjór.

Þessi saltbjór sem ég kom með kallast Gose. Saltiðbragðið kemur upprunalega úr vatninu við Goslar í Þýskalandi. Lesa má um sögu stílsins hér
http://en.wikipedia.org/wiki/Gose" onclick="window.open(this.href);return false;

Hér er uppskriftin og aðferðin sem ég studdist við. Ég notaði súrmalt og tveggja þrepa meskjun eins og talað er um í greininni. Saltaið var hágæða íslenskt sjávarsalt og gerið var W1007 German Ale
