Perhaps you’ve never heard of Kernza, a perennial grain. Yet the drought-tolerant grass might just show up in your next happy hour, as Tattersall Distilling Co. releases its new Tattersall Kernza Perennial Grain Whiskey.  

It is the first 100% Kernza whiskey in the country, and it is being launched with a tasting and celebration on April 29 in River Falls.
