"You don't pound it like a regular beer, you just sip it," Koch adds.
In 2017, only 68 casks were produced, creating 13,00 bottles available for purchase. The specialty beer is only brewed every two years, so aside from those bottles, the next batch won't be available until 2019 according to a representative for Sam Adams.
There's just one catch: The brew is illegal in 15 states in the U.S., including Alabama, Arkansas, Georgia, Idaho, Missouri, Mississippi, Montana, New Hampshire, North Carolina, Oklahoma, Oregon, South Carolina, Utah, Vermont and West Virginia, according to the company.
Koch says it's illegal "because of the high alcohol [content and] the unique brewing process," which he calls the "lunatic fringe of brewing."
"As a brewer, I'm okay with that," Koch tells "Secret Lives of the Super Rich." "To me, there's only one thing better than great, wonderful beer — it's great, wonderful beer that's illegal."
