Zachary Stern

Zachary Stern's grandfather, Marvin Sands, founded a humble wine business in 1945 at age 21.

That small operation has mushroomed into a publicly-traded behemoth now called Constellation Brands, which generates nearly $10 billion in annual revenue.

The company is known for its relentless streak of acquisitions. Subsidiaries include Robert Mondavi wine and Svedka Vodka.

Constellation also holds the rights to Grupo Modelo's U.S. beer business, including its Modelo and Corona labels.

Stern's uncles, Robert and Richard Sands, are former executives and current board members. His sister, Abigail Bennett, is also a billionaire.

The family received $1.5 billion (pre-tax) of cash to convert its enhanced voting shares to ordinary shares in 2022.
