====Propagation Characteristics====
[https://www.mbaa.com/publications/tq/tqPastIssues/2022/Pages/TQ-59-3-1015-01.aspx Carriglio et al. (2022)] compared propagation characteristics between WLP001 (California Ale Yeast), WLP830 (German Lager Yeast), and WLP518 (Opshaug kveik), using modern yeast propagation methods (12.5°P wort, 25°C temperature, 14.7 grams of yeast nutrient, constant aeration, recirculated with a pump, and with a total propagation time of 26 hours). The study measured attenuation, FAN consumption, final cell density, and final biomass production. They found that Opshaug did not uptake FAD any differently than the ale and lager yeasts. Opshaug had slightly less attenuation. They found that Opshaug kveik had a higher cell density than the ale and lager strain (~803 million cells per mL, versus ~461 million cells per mL for WLP001 and ~593 million cells per mL for WLP830). Aasen's Master's thesis showed similarly higher levels of cell density for kveik strains versus US-05 during fermentation ([[Kveik#Temperature_and_Growth_Rate|Temperature and Growth Rate]] below). The Opshaug kveik also nearly doubled the biomass production of ale and lager yeast. These characteristics may or may not extend to other kveik strains, and different propagation temperatures may produce different results for all characteristics measured <ref>[https://www.mbaa.com/publications/tq/tqPastIssues/2022/Pages/TQ-59-3-1015-01.aspx Comparison of Kveik with Conventional Saccharomyces Brewing Strains for Propagation Characteristics, Biomass Production, and Biomass Conversion Rate.
