Start with the name, because it is doing more work than it looks like. Tennessake is not sake, has none of sake's rice-wine brewing process, and shares only the word "rice" with the thing its name is punning on. It is a lager, brewed with rice sugars for a lighter body, then finished with real yuzu and fresh ginger. Borrowing a name from an entirely different beverage category is a bold move for a beer that then has to be judged on its own terms.
It mostly earns it. Yuzu is the kind of citrus that shows up more in recipes than in casual conversation - honeysuckle up front, then a tartness closer to grapefruit and lemon than to orange - and pairing it with ginger's spice instead of another citrus is the more interesting choice of the two. Tennessee Brew Works is positioning this one for the food-pairing crowd specifically, suggesting it alongside sushi, tempura, and ramen, which tracks: a rice lager built around yuzu and ginger has more in common with a dashi broth than with a summer shandy.
Availability is the one place this stays modest rather than triumphant - Tennessake is only sold in Tennessee, full stop, starting at the Nashville taproom this Friday and soon at the Lenoir City location. No wider distribution, no national rollout talk. Just a regional lager that picked an unusual name and an unusual flavor pairing and is content to let both stay a Tennessee thing for now.
