Tiamana is Maori for Germany or German. We brew German-style beers as well as 'new world' ales with earthy, herby German hops. Are we brewing by Reinheitsgebot? Tiamana beer is, in principle, not striving to brew by the 'Reinheitsgebot' (= the German 'purity law' that prescribes that only malt, hops and water may be used to brew beer). However, only ingredients that contribute to the flavour and composition of the beer are used - so some Tiamana beers comply with Reinheitsgebot.
