Winery Due Diligence Checklist for Buyers
By the time a buyer signs a letter of intent on a winery, they have usually walked the vineyard, tasted the wines and reviewed a summary of sales. Winery due diligence is the stage where those impressions are tested against records, permits, contracts and inspections. A thorough review can help a buyer confirm what it is paying for, identify issues to address in the purchase agreement and give its lender the information needed to evaluate the loan.
This checklist is general information for buyers of existing, operating wineries and vineyards. It is not exhaustive, and every transaction is different. Alcohol, land use, water, environmental and employment matters vary by state and locality and should be reviewed with qualified attorneys, accountants and other professionals. Nothing here is legal, tax or regulatory advice.

- A complete schedule of existing debt, liens and leases
Permits, Licenses and Compliance
- All federal, state and local permits and licenses, including tasting room and shipping approvals

Using Diligence Findings
Diligence rarely produces a perfect picture. Findings may lead a buyer to renegotiate price, ask the seller to resolve issues before closing, add specific representations to the purchase agreement or hold back part of the price. Sharing organized findings with the lender can also help the loan review move forward.
