Okay so you don't think they planned for growth? I do Tequila and same thing. It takes long time to make it. If not Silver it takes over a year. If in liquor business you have to plan for growth.
I guess it all depends on how many tons are actually being harvested per acre...
So 1 ton of grapes yields about 60 cases or 720 bottles. If you put all that together, a very low-yielding vineyard that produces 2 tons per acre makes about 1,440 bottles, or 120 cases, while an acre that yields 10 tons produces about 7,200 bottles, or 600 cases.
