(Maybe you’ve been to the little kiosk outside of New Meadows that marks its precise location.) While the overall climate is impacted by its proximity to the Pacific Ocean, variations in sea level, and atmospheric conditions, the Snake River Valley receives a markedly similar amount of sunlight per day and per season as these longstanding fixtures in the wine industry. In other words, Idaho is a great place to make wine, and the state is host to an increasingly renowned wine country. But there’s a lot more to producing fruits suitable for the bottle than sitting halfway between the equator and a North or South pole, and the capacity for a vine to grow is hardly an indicator of an award-winning vintage. Broadly speaking, a complex system and network of soil, water, and temperature interacts to render fruits worthy of being bottled, and location is just the start |
