- and its Challenges in Processing
- and its Challenges in Processing
The U.S. Wine Industry:
• 8,000 wineries
• 30,000 grape growers
• 1,000,000 acres of vineyards
• $ 4 billion crop value (grapes)
• $ 12 billion value-added products (wine)
• $ 162 billion economic impact www.ngwi.org
The wine business
is a cruel and shallow money trench,
a long-stemmed hallway
where thieves and pimps run free
and the weak die like dogs ...
So You Wannabe a Wine Industry Supplier?

MicroOxygenation
MicroOxidation?
1. Mixing/diffusion in tank vs column of bubbles
2. Delayed/indirect reactions and quality control
3. Destruction of aromas
4. Production of disulfides-related off-odors
5. Encouragement of spoilage organisms
6. Limiting aging potential
