Gem 73 Winery has officially opened its doors in the Sunnyslope region of Caldwell. The property features a vineyard spanning 62 acres designed to prioritize the consumer experience through tours and gathering spaces.
Why it matters
The owner aims to capitalize on the growth potential of the Idaho wine industry to meet the rising demand from younger consumers for experiential visits. This expansion comes despite broader industry challenges, as U.S. wineries faced $1.2 billion in lost sales during 2025.
The new site sits on 62 acres of vineyard featuring sandy, chalky loam soil, which assists in controlling vine growth. There are currently approximately 65 wineries operating throughout the state of Idaho.
