Crush season is the most financially complex 6 to 10 weeks of the year for most wineries. Revenue isn’t arriving yet, costs are accelerating, crews are on payroll, and the records that will determine your true cost of goods for this vintage are being made right now, or quietly missed right now.
Most winery owners have the viticulture side of harvest dialed in. The accounting side is where things fall apart: grape costs coded to the wrong vintage, labor in operating expense instead of inventory, and by the time your CPA sits down with your books in January, the trail is cold.
This crush season accounting checklist covers what to track during crush, why each item matters, and what accurate records make possible when the season wraps. Start with grape costs, since that’s where most of the dollar value lives.
Grape Cost Tracking: Coding Each Lot To The Right Vintage
Every grape purchase (whether from your own estate or an outside grower) needs to land in the right vintage lot the moment the invoice arrives.
In practice, that means your chart of accounts should separate grape costs by vintage year, not just by varietal. A Cabernet Sauvignon from the 2026 harvest is a different asset from your 2025 Cab still aging in barrel. Mixing them distorts your per-vintage cost basis and makes accurate margin analysis impossible at the time of sale.
For estate fruit, calculate and record the internal transfer price at harvest (even if it’s an estimate you’ll true up later). The IRS expects inventory to reflect actual production costs. Leaving estate fruit at zero until tax season is a common error that creates inventory accounting problems downstream. For more on how winery inventory accounting works across the full production cycle, our winery accountants have a deep overview on the site.
With grape costs captured accurately, the next big number to track is harvest labor, which flows directly into those same vintage cost accounts.
Payroll Records During Harvest: Separating Direct Labor From Overhead
Harvest payroll is one of the biggest cost categories of the year, and how you classify it affects both your COGS (Cost of Goods Sold, the direct costs tied to making the wine) and your year-end tax picture.
Direct labor (the crew working the crush pad, operating the press, sorting, moving fruit) should be capitalized into inventory as part of your wine production costs, not expensed as an operating cost in the current period. Overhead labor (managers, tasting room staff keeping the lights on during harvest) stays in operating expense.
The practical step: your payroll records during harvest need to tag hours by function, not just by employee. A harvest worker splitting time between sorting and tasting room coverage should have those hours tracked separately. Blending the two means you’re either overstating or understating your true production cost, and the error compounds across each vintage.
If you’re using H-2A workers this harvest, keep their housing and transportation costs in a dedicated cost center. Those costs are deductible but need to be tracked separately to survive scrutiny. The California Employment Development Department (EDD) has guidance on agricultural employer requirements specific to California operations.
Accurate labor classification also shapes your cash flow picture directly, because payroll is typically the largest weekly outflow during crush, and misclassifying it means your real production costs stay hidden until the close.
Cash Flow During Crush: When The Gap Opens And How To Close It
Crush season is defined by a cash flow gap: you’re paying for everything right now and collecting revenue weeks to months later.
To manage that gap, you need a weekly cash position update during harvest, not a monthly one. What’s going out (payroll, grower invoices, supplies, barrel orders)? What’s coming in (wine club shipments, tasting room deposits, DTC web sales)? The delta tells you when you’ll need to draw on your line of credit and by how much.
Set a weekly cash review on the calendar for every week from late August through mid-November. If you’re using accounting software, run a cash flow statement at the start of each week. If you’re working with a spreadsheet, keep a rolling 8-week projection. The wineries that make it through October without a financing crisis are the ones tracking cash weekly, not reacting to it monthly.
Cash flow tells you when you’re running short. Your barrel and tank records tell you what you’ve built so far and what those assets are actually worth on the balance sheet.
Barrel And Tank Tracking: What Goes In Must Be Recorded
Every barrel filled during crush is an inventory asset, and it needs to be recorded as one at the time of fill.
That means logging the barrel number, fill date, varietal, vintage year, volume, and source lot right then. Not after harvest, not when things slow down in December. At the time of fill, because that’s the only moment you have all the information in one place.
Barrel costs (the purchase price or lease cost) need to be allocated across the volume they’ll hold and spread over the useful life of the barrel, typically 3 to 5 fills for most French and American oak. A barrel purchased for use across multiple vintages shouldn’t be fully expensed in year one. That inflates your current-year costs and understates future vintage COGS.
Tank records follow the same logic. Any wine moved from tank to barrel or barrel to tank gets a transfer record with the same metadata. Your winery books should tell the story of where every gallon went, not just where it ended up. That production trail also feeds directly into your TTB reporting obligations, which is the next item on the checklist.
Federal Excise Tax: Tracking Production Volume As You Go
Federal excise tax on wine is administered by the Alcohol and Tobacco Tax and Trade Bureau (TTB), and your liability is calculated based on the volume of wine removed for consumption or sale, not on what you produce.
That said, your production records during crush are the foundation for your TTB operations report, which is filed monthly. Every gallon received, produced, on hand, and lost needs to be accounted for. Errors in the monthly report create reconciliation problems that are time-consuming and expensive to unwind.
Keep a running production log during harvest: gallons received by lot, gallons transferred to fermentation, losses at each stage (stemming, pressing, settling). Your winemaker likely tracks this for winemaking purposes, and the accounting team needs access to the same data for the TTB report and for accurate COGS costing. If those two record systems aren’t talking to each other, you’re duplicating work and creating reconciliation risk.
All of these records (grape costs, labor, cash flow, barrels, TTB production logs) feed into the same outcome: knowing exactly what this vintage actually cost you, which is what makes the next section worth reading.
What Does Accurate Crush-Season Accounting Make Possible?
Accurate harvest records aren’t just for tax season. They’re the foundation for every financial decision you make about the 2026 vintage for the next 2 to 5 years.
When you know your true cost per ton received, your per-barrel production cost, and your labor allocation by lot, you can price your 2026 releases with confidence. You can decide which lots to hold for reserve and which to sell in bulk without guessing. You can compare this vintage’s cost structure to last year’s and understand whether efficiency is improving or eroding.
Without that data, you’re managing on feel. In a market where margins are under pressure from rising grape prices, labor costs, and distribution competition, managing on feel is increasingly expensive.
The winery owners who track these numbers during crush close harvest knowing exactly where they stand, rather than spending spring trying to reconstruct what happened in September. Two practical questions come up every year on implementation, so let’s address both.
How Often Should Winery Owners Review Their Books During Harvest Season?
Weekly, without exception during the crush window.
A weekly review doesn’t need to be a full month-end close. It needs to cover three things: cash position, labor classification check (are this week’s payroll hours coded correctly?), and a quick scan of grape invoices received to confirm they’re coded to the right vintage lot. That’s a 30-minute review that catches errors costing 10 hours to fix in January.
The month-end close for September and October should happen promptly, not in December. Getting those periods closed within 3 to 4 weeks of month-end keeps your numbers current and surfaces any costing errors while the winemaking team still remembers what happened.
The second question is about tools, and the answer directly shapes how feasible that weekly review actually is.
Should Your Winery Use Accounting Software Or Spreadsheets For Crush Tracking?
Accounting software (ideally one that integrates with your winery management system) gives you real-time visibility that spreadsheets can’t match.
The most common setup for small to mid-size wineries is QuickBooks Online or Xero for the accounting layer, connected to a winery management platform like VinNow, eCellar, or Commerce7 for DTC. The winery management system tracks the tasting room and wine club; the accounting software tracks production costs, payroll, and vendor invoices.
Spreadsheets work if you’re in your first harvest year, but they create problems as volume grows: no audit trail, no real-time collaboration with your bookkeeper, version control headaches. If you’re three or more harvests in and still on spreadsheets for your production costing, that’s a conversation worth having with your winery accountants about what upgrade makes sense for your scale.
