Production, crush, barrel-storage and bottling areas
NAPA COUNTY PROPERTY OWNERS
Reviewed August 22, 2026 · Updated for current federal bonus-depreciation guidance
Wine Country property mixes production, hospitality and land.
Napa County properties can combine valuable land, winery production areas, barrel storage, tasting rooms, restaurants, lodging, apartments and broad agricultural improvements. A defensible study separates each operating use and reconciles the real-estate basis with machinery and equipment already depreciated elsewhere.

WHY IT MATTERS
Move eligible basis into faster recovery periods.
Winery classifications should follow function. Production and equipment-support areas differ from finished-goods storage, offices, retail tasting rooms and hospitality space. Vineyard land, vines, irrigation, equipment, later expansions, tenant work and acquisition allocations may have separate tax treatment, so each cost pool and placed-in-service date needs documentation rather than assumption.
Plain English: you are not creating a new deduction. You are identifying when supported pieces of the property may be depreciated.

SHOW ME THE NUMBERS
Illustrative Napa County winery example
Illustrative only. This assumes a 37% federal marginal rate where shown and that the owner can currently use the deduction.
- Property value
- $12,000,000
- Estimated depreciable basis
- $7,200,000
- Potential faster basis
- $1,440,000 to $2,160,000
- Potential upfront federal effect
- $533,000 to $799,000
- Study or comparison benchmark
- $15,000 to $30,000+
This is a timing illustration, not guaranteed permanent tax savings. California commonly requires a separate depreciation schedule because it generally does not conform to federal bonus depreciation.

STRAIGHT ANSWERS
Frequently asked questions.
Can a Napa winery receive a cost segregation study?+
Potentially. The study must distinguish the building and land improvements from production machinery already capitalized elsewhere, then document production, storage, tasting, retail and hospitality functions.
Are vineyard land, vines and irrigation all treated the same?+
No. Land is not depreciable, while vines, irrigation and other agricultural improvements can involve different recovery rules and facts. The owner’s CPA should confirm treatment and the study must avoid duplicating separately scheduled assets.
Could winery production space also need a Section 168(n) review?+
Potentially. Current qualified-production-property rules are separate from ordinary cost segregation and have their own activity, construction, acquisition, use, timing and election requirements. California does not conform to that federal allowance.
Is the free estimate a completed study?+
No. It is an illustrative screen using the facts you provide. No engineering takeoff, professional certification or tax opinion is included. Technical work begins only after a signed and paid engagement.
Does my CPA need to approve the study first?+
No. It is smart to ask whether you can currently use additional depreciation, but the paid study does not require advance CPA approval. Your CPA makes the final filing decision.
Do you guarantee tax savings?+
No. A study accelerates the timing of eligible depreciation. Results depend on basis, property facts, placed-in-service dates, passive-loss rules, tax rates and the owner's filing position.
