I suspect This will impact the lower end of the market (under $30) and the mid range ($30 to $50). The high end wines and super high ends (above $100) will not be affected as much, as their grapes are both limited and often under long term contracts.
I suspect that the wine spill of Rodney Strong wine into the Russian River a couple of weeks ago will have some small impact, 97,000 gallons worth!
A local super market has 40% off about every 4 weeks -——
That’s when I buy!
