Bridging The Gap Between Winemaking and Accounting

Bridging the Gap Between Winemaking and Accounting with Rachel Smith, Owner of Northwest Wine Accounting

Rachel Smith has spent her career at the exact intersection where winemaking data meets financial reporting, a place most wineries leave unmanaged until something goes wrong. As the owner of Northwest Wine Accounting, she specializes in winery cost accounting and works directly with winemakers and accounting teams to build the workflows that make accurate financial reporting possible. Her work is hands-on: she sits down with new winery clients, goes through their chart of accounts line by line, and helps them figure out what is production-related and what is not, a distinction that shapes every financial statement the business produces from that point forward.

She sat down with Lauren Heindel to walk through the specific roles winemakers and accountants play in winery cost accounting, what data needs to move between those two functions and how often, and what a winery should actually be getting out of the process beyond a year-end tax filing.

The central tension in winery financial management is that the people who make the wine and the people who report on it are working with fundamentally different information. Winemakers track gallons, cases, and movements. Accountants track dollars. Neither group has the full picture on their own, and when the handoff between them is unclear or infrequent, the result is financial statements that reflect compliance rather than operational reality. That gap is exactly what Rachel’s work is designed to close.

In this episode, we cover:

Why winemakers and accountants need each other

Cost accounting in a winery is not something either the winemaker or the accountant can do alone. The winemaker has information that does not exist anywhere in the financial system: how many gallons were produced, how many cases were bottled, what moved out of the winery and how. The accountant has the financial records, the invoices, and the tools to assign dollar values to all of it. Neither person can produce an accurate cost figure without what the other knows.

The flow works in one direction: production data from the winemaker goes to the accountant, who then assigns costs to those unit movements and records them in the financial system. When that handoff does not happen cleanly, the accountant is left with high-level averages that are adequate for tax filings but not useful for the operational decisions winery owners actually need to make.

The consequence of not having lot-level cost data is that every financial decision gets made with blurry numbers. You know roughly what wine costs to make. You do not know whether your Pinot Noir lot from the new vineyard block is actually profitable, or whether the rosé program that felt like a good idea is contributing to or diluting your margins.

What information your accountant needs from production

The data a winery accountant needs to perform cost accounting covers both bulk wine and case goods, and it tracks all the inflows and outflows at each level.

For bulk wine, the accountant needs to know how many gallons were produced during the period, how many were purchased from outside sources, and what all the outflows were: gallons bottled (and how many cases that produced), gallons sold bond-to-bond, gallons transferred out of the facility, and any significant unusual losses that go beyond normal operational variance. What the accountant is building is a complete flow statement: wine that entered the system, wine that left, and what remains at the end of the period.

For case goods, the same logic applies. The accountant needs the number of cases bottled, any finished cases purchased from outside (shiners), and all the ways cases left: sales through every channel, samples, glass pours, tasting room use, family use, breakage, and damage. The goal is to reconcile what came in, what went out, and what the ending inventory count shows.

Rachel notes that much of this information overlaps with what wineries already report on the TTB 5120.17 Wine Premises Operations Report. For accountants working with clients who do not have detailed production records, the filed TTB report can serve as a starting point for reconstructing the juice flow data needed for cost accounting.

Splitting the work in your winery management platform

In a well-structured winery accounting workflow, the winemaker and the accountant each own specific parts of the data entry process. Getting that division right prevents both gaps and duplication.

The winemaker owns all operational entries: work orders, lot movements, production records, and the direct costs they can attach to specific lots at the time they occur. If a grape invoice arrives and the winemaker knows which lots it applies to, they can enter that cost directly. The same applies to bottling supplies, additives, glass, corks, capsules, and labels. The winemaker is the right person to make those entries because they know which lot each cost belongs to, and doing it at the time the cost is incurred is more accurate than trying to reconstruct it months later.

The accountant picks up what the winemaker cannot reasonably handle. Shipping charges, pallet fees, overhead allocations, and the miscellaneous costs that do not attach cleanly to a single lot all belong to the accounting team. The accountant’s job is to compare what is in the winery management system against what is in the financial system (typically QuickBooks or similar), identify anything that did not make it through, and allocate it appropriately.

The principle Rachel comes back to is reconciliation: the two systems need to tell the same story. If costs are in the books but not in the winery management platform, the wine is under-costed and the margin looks better than it is. If costs are in the platform but not accounted for in the books, you have the opposite problem. The accountant’s monthly job is to close that gap.

Who decides what counts as production overhead

Overhead allocation is where the complexity increases, and where the winemaker’s input matters more than most people expect.

The decision about what is production-related and what is not cannot be made by the accountant alone, because many of the line items in a winery’s chart of accounts are genuinely ambiguous. Repair and maintenance: is that a production cost or a facility cost? Small tools and equipment: production or operations? Rent: which portion applies to the production areas? These questions do not have universal answers. They depend on what the winery actually does and how it operates.

Rachel’s process with new clients is to sit down with both the winemaker and the accounting team, pull up the P&L line by line, and work through each category. Is this production-related? Do we want to capitalize it into the cost of wine? Once those rules are established, the accountant can apply them consistently going forward without re-litigating every line item each month.

The reason this matters: overhead capitalized into the cost of wine eventually flows through cost of goods sold when the wine is sold. Overhead not capitalized hits the operating expense line immediately. The difference affects margin, inventory valuation, and the accuracy of the break-even analysis a winery needs to evaluate its pricing strategy.

Why monthly cost accounting produces better decisions

Most small wineries only do cost accounting once a year, when the tax accountant needs it. Rachel’s position is that this is the minimum acceptable standard, not a best practice.

Doing cost accounting only at year-end means that for eleven months of the year, a winery owner is making pricing, production, and channel decisions without accurate cost data. If a new lot is bottled in March and the cost is not calculated until the following April, the pricing decision made at bottling is based on a guess. If margins are deteriorating in the tasting room, the problem does not surface until a year later.

Monthly reconciliation means that every time wine is bottled, the cost is calculated. Every month, the work-in-progress inventory on the balance sheet reflects actual current value. Every month, the cost of goods sold on the P&L is accurate rather than estimated. The financial statements become a reliable tool for decision-making rather than a compliance artifact that shows up once a year.

The six financial deliverables a winery should expect from cost accounting

When cost accounting is working well, it produces outputs that go well beyond the annual tax filing. Rachel walks through the six key deliverables a winery owner should expect to receive.

Bottled cost per SKU at bottling time is the starting point. This is the cost to produce one bottle of each wine, calculated at the time it is bottled and broken down by lot and SKU. It is the foundation for every pricing and margin analysis that follows.

COGS and gross margin by sales channel tells you whether your tasting room, wine club, and distributor channels are actually performing differently. Most wineries know that DTC margins are better than distribution margins in theory. Accurate channel-level COGS lets you see by how much, for each wine.

Inventory valuation for work-in-progress and finished goods gives the balance sheet an accurate picture of what the winery’s inventory is actually worth. This matters for lenders who use inventory as collateral, for business valuations, and for owners who want to understand the capital they have tied up in aging wine.

Cash flow from inventory shows how much cash the winery is investing in building inventory each period, separate from the profitability picture on the P&L. A winery can be profitable and cash-constrained at the same time if it is building inventory faster than it is selling it, and this metric surfaces that dynamic.

Sell-through rates and run-out dates tell you how long current inventory will last at current sales velocity, by SKU. This informs both production planning and sales strategy.

Break-even analysis uses your overhead costs and contribution margins to calculate how many cases you need to sell to cover operating expenses. Without accurate cost data, this calculation cannot be done.

Rachel recommends asking your accountant which of these six deliverables you are currently receiving and at what frequency. If the answer is “just the year-end P&L,” that is a useful conversation to have. Each of these outputs requires the same underlying cost data. Once the cost accounting infrastructure is in place, generating all six is largely a matter of running the reports.
