The post earlier this month, in which Sam Cecil briefly outlines the careers of the many Beam family distillers, raised a question about the yeast all of those Beams were using, not just at Jim Beam but at Heaven Hill, Four Roses, Yellowstone, Maker's Mark, Barton, Stitzel-Weller, Early Times, and many others.
The specific question: Jim Beam's yeast has a reputation for imparting a 'foxy' taste, a characteristic not associated with any other producer, despite having Beams in their lineage. How come?
Historically, 'yeast making' meant propagating a strain from a wild source. Although the Beams all started from the same place, with the same yeast mash recipe, and were all taught the same organoleptic standards, each distiller in each generation would have made his own subtle adaptations after years of practice, and would have passed his way of doing things on to his son.
I say 'son,' knowing that some Beam family distillers were trained by their grandfathers more than their fathers.
Either way, the genealogy of the yeasts is essentially that of the yeast makers.
David Beam (1802-1852) had three sons who became distillers. If you're a fan of Underworld, think of them as the three sons of Alexander Corvinus.
The youngest, Jack Beam, started Early Times and although his only son followed him into the business, there was no third generation. That line died out. It's unknown if that strain was preserved and passed on to the people who revived Early Times after Prohibition, but it seems unlikely.
The other two were Joseph B. Beam and David M. Beam. Those two traditions split more than 150 years ago, and there have been many other subdivisions since.
Each of them had two distiller sons. Joseph B. had Joseph L. (Joe) and Minor Case, and David M had the famous Jim Beam and his brother, Park.
We know from Booker Noe, Jim Beam's grandson, that the Jim Beam yeast was 'caught' by Jim on his back porch in Bardstown as Prohibition was ending and he prepared to build a new distillery.
When Park's son, Earl, left the Jim Beam Distillery in 1946, he took the Jim Beam yeast with him to Heaven Hill, replacing the Joe Beam yeast Joe's son Harry was then using. Under Earl Beam, Heaven Hill's bourbon had a reputation for being oily, but not 'foxy' like Beam.
I should note that, to me, the 'foxy' yeast characteristic is only noticeable in the white label Jim Beam expression.
It's hard to say what changed at Heaven Hill. It may have been the water. Yeast can change for very subtle reasons -- different water, different atmospheric conditions, different airborne microorganisms, different mash temperature, a different amount of back set, etc. The loss of the 'foxy' characteristic may have been deliberate, or an accidental by-product of different practices in a different place.
In addition to training his sons Joe and Minor Case, Joseph B. Beam may also have trained Will McGill, since he was father-in-law to Joe's wife, who was Will's sister, Katherine. McGill must have been a good student because he became Pappy Van Winkle's master distiller at Stitzel-Weller after Prohibition.
It is likely that they also learned from Joe's older brother, Minor
Case, who was 11 years Joe's senior. Minor had his own distillery at
Gethsemane, which made the brand Old Trump, and which eventually merged
with the nearby Yellowstone distillery. Joe and Will worked together at many different distilleries during their early careers, including at the Tom Moore distillery, today's Barton.
So the Stitzel-Weller yeast that made its way to Maker's Mark would have originated with Joseph B. Beam and probably went through Minor Case to get to Will McGill, and from him into the hands of Elmo Beam, Joe's firstborn, who would already have been familiar with his father's version.
That Pappy gave the yeast to Bill Samuels Sr. is known, but what Elmo actually used is not, at least not by me. Sam Cecil probably knew, since he followed Elmo at Maker's Mark.
Among his many feats, Joe Beam restarted Four Roses (then in Shively) after Prohibition, and employed some of his seven distiller sons there, as well as some of their sons. Seagram's bought Four Roses during WWII and Roy's son, Charlie, spent most of his career with Seagram's, where he developed the Eagle
Rare Bourbon brand before finishing his career at Four Roses in
Minor's son, Guy, was a distiller or master distiller at several different distilleries, including Heaven Hill, Fairfield, and Cummins-Collins. During Prohibition he was a distiller in Canada. Guy had two distiller sons, Burch and Jack. A third son, Walter, who was better known as Toddy, operated a liquor store in downtown Bardstown that still bears his name.
Jack worked for Barton. The two brothers who recently started the micro distillery
Limestone Springs in Lebanon are descended from Guy.
Nobody is catching wild yeast these days and if distillers want to tweak their yeast, they do it in the lab, not on a back porch as Jim Beam did.
