HAMMONDSPORT - Dr. Konstantin Frank Winery commemorated its 55th anniversary this weekend as it moves into its fourth generation of Frank ownership.

The winery, known for its renowned Riesling varieties, held a celebration with family and friends Saturday evening, as it has experienced much success since viticulturist Dr. Konstantin Frank founded it in 1962 after emigrating from Ukraine.

“Research shows us that approximately 30 percent of all family-owned businesses survive into the second generation and only 12 percent will survive in the third generation,” said Fred Frank, Dr. Frank president and grandson of Dr. Konstantin Frank, in a speech to guests Saturday evening. “Only three percent of all family businesses operate at the fourth generation and beyond.”

“Beating the statistics did not come without sacrifice and many people working alongside of our family, some for many generations.”

Coming this far was made possible by years of dedication from the staff that make up the Dr. Frank family.

Fred Frank’s daughter Meaghan Frank became general manager last year, and will eventually succeed her father as president. The Dr. Frank team includes other members of the Frank family as well, along with a loyal staff who have been with the business for years.

During his speech Fred Frank thanked his wife Maryclaire, his mother Margrit, sister Barbara, and cousin Eric Volz, the winery’s vineyard manager, for everything they’ve sacrificed for the business.

He also expressed his appreciation for members of his crew who have been with the winery for the long run: head winemaker Mark Veraguth for 27 years, retail manager George DiTomasso for 24 years, Allyn Brand for 19 years and Colleen Yale for 17 years.

“Everyone sooner or later becomes a member of our family, and it is with the greatest joy that I would like to propose a toast, to family!” Fred Frank said.

The Dr. Frank main tasting room is open year-round from 9-5 p.m. Monday through Saturday, and noon-5 p.m. Sunday. Its newly-opened 1886 Reserve Tasting Room is open June through October at 11 a.m. and 2 p.m. Friday and Saturday and at 2 p.m. Sunday via online reservation.

Dr. Frank Wine Cellars is located at 9683 Middle Road, Hammondsport.
