Numbers that Grow Wineries: 5 Costly Financial Blind Spots
Monday, June 22nd, 2026
About the Speaker
Zane Stevens is the Founder of Protea Financial and has specialized in the wine and beverage world since 2014, beginning his career at KPMG before building a firm dedicated to operational accounting for wineries. With more than twelve years spent in the day-to-day details of winery books, he brings hands-on expertise in bulk-to-bottle costing, TTB compliance, club and DTC accounting, and M&A. Named to the North Bay 40 Under 40 in 2024, Zane is a firm believer that good numbers grow good businesses.
What we’ll cover:
- No true cost per case: why pricing without a real cost-to-produce means every price is a guess
- Casual inventory: treating your single biggest asset as an estimate, and how to value and reconcile it properly
- Cash vs. accrual confusion: how seasonality hides whether you actually made money
- Flying blind on margins: tracking margin by channel and against benchmarks so you know what “good” looks like
- Tax-first thinking: why optimizing the tax bill before the business is profitable starves growth
We will close with what good actually looks like in practice: financials you trust monthly, cost and margin by wine and channel, a short KPI dashboard, and tax handled as the last step rather than the first. Bring your lunch and your questions.
Who Should Attend:
This session is designed for winery owners, general managers, bookkeepers, and anyone responsible for pricing, inventory, or financial decisions in the Virginia wine trade.
