Notes from Brad, Northern Brewer Head Brewer:

“This recipe may seem overly simple, but that is for a reason. The true purpose of the intentionally basic grain bill and hop schedule is to highlight a truly unique yeast strain. Omega Yeast has released a single strain of Norwegian Kveik, and the results from this strain are truly impressive. Originally isolated from Omega’s Hornindal Kveik yeast blend, Lutra™ is a rapidly fermenting yeast strain with an incredible neutral flavor expression within a wildly remarkable temperature range. Fermented at traditional ale temperatures around 68F, Lutra™ produces nearly lager-like beers with an exceptionally clean and crisp finish with minimal ester production. On the other end of the temperature spectrum in the low 90F range, Lutra™ remains quite clean yet expresses a gentle ester profile that brings to mind the flavors of a traditional Kolsch strain. In addition to its incredibly clean and crisp flavor profile, Lutra™ is an absolute beast with an insatiable hunger for malt sugars - full attenuation can be achieved in mere days. With lower temps, I have found that this recipe can attenuate in 4 days, while elevated fermentation temperatures pare this down to 3. Of course, there are many factors that influence its performance, but it is a very rapidly fermenting yeast strain to be sure. Ensuring proper aeration/oxygenation will give the yeast cells everything they need to chow down on your wort to flip a batch at break-neck speed. Although temperature control is not particularly important, taking this strain up to normally forbidden heat levels will not be a detriment to this recipe. Go ahead, crank this one up and let it rip - you will be surprised at how quickly and cleanly Lutra™ gets the job done, and then it seems to magically drop out of suspension leaving a relatively clear beer in short order. It may be a “new” Kveik strain to most, but Lutra™ is certainly a legend in the making.”
