Organic Grapes and Organic Wine: Why a Winery Buyer Must Trace the Whole Production Chain

By Matthew Martinez, Founder, CEO & Managing Broker, Diamond Real Estate Group. California DRE #01869679.

A winery acquisition may include organically grown grapes, wine made from those grapes and labels with different organic claims. Those assets should be evaluated at their actual stages. The growing description alone does not establish which statement can appear on every finished bottle.

This is particularly relevant when a buyer plans to combine a vineyard purchase with an estate wine brand. The intended farming program, production method and finished-product presentation need to fit together.

The finished-wine claim has additional requirements

USDA’s organic alcohol guidance explains that alcoholic beverages must meet organic requirements and TTB regulations. Added sulfites limit wine to the eligible made-with category rather than use of the USDA organic seal.

Read the applicable requirements with the certifier and wine compliance advisers. The distinction concerns a defined labeling framework; it should not be converted into an unsupported health or quality ranking between wines.

Identify the product represented by each certificate and label

A vineyard’s certification concerns the operation and scope covered by that certification. The finished wine involves further production and handling steps. A buyer should understand which grapes, lots and products the available documentation actually supports.

For a hypothetical estate with three wine lots, one label approval or one certified growing block is not a complete explanation of all three products. Follow each lot’s relevant production story instead of assuming the estate name makes them interchangeable.

Future intentions do not rewrite existing inventory

A purchaser may intend to change the vineyard or winery program after closing. That proposal should be distinguished from the status of wine already produced.

The acquisition analysis should identify which existing products can be sold under their supported descriptions and which future products are part of a separately developed plan. A planned change cannot simply be applied backward to make existing inventory fit a new marketing claim.

Read the production service arrangement

If another facility produces, handles or bottles the wine, establish the roles and requirements applicable to the intended product. A property’s attractive vineyard setting does not itself answer how an offsite production arrangement supports an organic claim.

The broader choice between owning a facility and using outside services has commercial consequences as well. Compare the service scope, actual operating costs and timetable with the business being acquired.

Model the commercial case separately from eligibility

Suppose a hypothetical plan assumes a $4 higher realized bottle price on 5,000 bottles after a production change. The modeled revenue increment is $20,000. It remains a sales assumption, even if the intended product ultimately qualifies for the proposed label.

Any additional certification, production or selling expense needs its own place in the model. Label eligibility does not demonstrate consumer demand at the assumed price or establish that the revenue increment is all profit.

Keep the property decision connected to the wine program

A buyer may value a property for its residence, agricultural setting and ability to support a particular operation. Establish which parts of that operation are actually included and which require a future arrangement.

That distinction allows a comparison between an existing supported business and an estate whose appeal depends on creating a new brand or production program. Both may be worth considering, but the costs and evidence differ.
