Lothar Kettern, Fio "Piu Piu" Riesling Petillant

Everybody’s doing Pet Nat, but few do it as well! This is a simply lovely rendition of Riesling, true to its roots, but done another way. Not a hint of funk gets in the way of the wine’s dry and salty Mosel dialect. Now a blend of wines from 2022 and 2023.
