Even in case you assume you realize an end result, you continue to have to try it out. An thought is only a speculation till you’ve got proof. So it’s in science, and so it’s in farming. For Mike Swanson, who strives for a contented mix of science and farming, testing and gathering information is a driving power.
Collectively together with his spouse Cheri, Swanson co-owns and operates Far North Spirits in Hallock, Minnesota, simply 25 miles from the Canadian border. On his flat patch of prairie land, Swanson doesn’t simply make spirits. He additionally grows each grain used to make the whiskeys and gins he produces, working as a real farm distillery. Yearly, he vegetation about 100 acres of rye varieties, utilizing some varieties akin to AC Hazlet and Oklon, whereas additionally bringing in heirloom and heritage varieties to check out. This 12 months, he planted Keystone Rosen, a pre-Prohibition period rye from Pennsylvania, the Keystone State. With every heirloom crop, Swanson will get an opportunity to check out a brand new taste profile whereas additionally build up his personal private seed financial institution.
However the farmer-distiller doesn’t simply develop heirloom grain for the enjoyable of it. Swanson is following the proof.
In 2015, Swanson partnered with the Minnesota Division of Agriculture to review whether or not the number of grain used to make whiskey meaningfully adjustments the style. It looks like widespread sense, however surprisingly, Swanson couldn’t discover any analysis on the subject. “I needed to entertain the concept there wasn’t going to be any distinction in any respect, as soon as we fermented and distilled,” Swanson says. “I used to be open to that chance. It’s important to be, as a scientist.” So, he created and carried out the examine himself.
On the identical plot of land, Swanson grew 15 totally different types of rye. If he managed for all different elements—local weather, soil sort, planting—and used the identical mashing, fermentation and distillation course of on every grain, would there be a distinction within the spirit’s last style? He wished to know.
“We put the distillate in entrance of as many noses and palates [as] we might to determine whether or not or not folks had been selecting up on variations between these distillates. And we discovered there was a reasonably vital distinction,” says Swanson. “There have been a number of older, open-pollinated varieties that basically didn’t style superb. However then there have been a number of that had been completely gorgeous. And what fascinated us was that the entire hybrids form of tasted the identical.”
Time and time once more, the flavour of the heritage and heirloom grains outperformed the hybrid rye varieties—however that doesn’t imply hybrids don’t have their place. Swanson nonetheless grows hybrid grains, akin to the favored AC Hazlet, as a result of they “are extremely strong within the area,” he says. “They provide lovely requirements, they yield astronomical quantities. They’re actually well-designed hybrid grains.” These hybrids type the bottom of spirits akin to Swanson’s Rocknar Minnesota Rye. The rye is blended with malt barley and heirloom corn to create a clean and—because of the hybrid grain—constant taste profile.
Whereas hybrids may produce a extra strong yield, taking the time to check heritage varieties, and even to deliver again forgotten grains, it’s about extra than simply yield. It’s about prioritizing taste, prioritizing the enjoyment of the spirit over all else. “There was a range from Oklahoma, they’ve been round fairly some time referred to as Oklon. And it didn’t develop very nicely up right here. And it didn’t mill or mash very nicely, and it tasted terrible coming off the nonetheless. However after we pulled it out of the barrel, it was superb,” he remembers. One other selection from Wisconsin referred to as Spooner Rye additionally proved troublesome. “In each circumstances, I used to be actually disillusioned as a result of I used to be like, ‘I don’t need to develop that stuff once more.’ It was a ache. However proper now, I’ve eight acres of Oklon within the floor as a result of it tastes superb.”

Swanson encourages different distillers to get as concerned as they’ll within the agricultural aspect of the method. Some, like him, may be capable of develop their very own grain, a practice that dates again a whole bunch of years. Others won’t have that chance, however he would encourage them to purchase native grains and communicate with the farmers about which selection they use and why. By creating the agricultural aspect of distilling, the tip person expertise will get higher and higher.
“To me, that’s form of the romance of heirloom,” says Swanson. “You study what makes these grains nicely tailored for the place that they got here from. What was that atmosphere like? Was it over in Russia? Was it in Poland or was it in Estonia?…If you begin elevating the agricultural facets of whiskey, it turns into a lot extra lovely.”
