Ollenaut Hele Lager is the first beer released in the Kaineken sub-brand, a non-alcoholic series whose name plays on the Estonian word "kaine", meaning sober. As the opening beer of the series, it established the format the rest of the Kaineken range follows. Rather than removing alcohol from a finished beer, the recipe uses a specialist yeast strain that does not ferment all available sugars into alcohol, keeping the ABV at 0.5% from the outset. Brewed at the Ollenaut brewery in Saku, it is positioned as a crisp, clean expression of the Northern lager style.
