EU Small Wineries: Track Fermentation and Nail Your Blend Costing — AskBiz Shows How
Fermentation losses of 5-15 percent are normal, but without tracking them per tank and variety you cannot price blends accurately. AskBiz connects harvest intake, fermentation records, and bottling output so you know the true cost of every cuvée.

Why fermentation tracking matters for small wineries#
A typical EU small winery producing 40,000-120,000 bottles faces fermentation losses of 5-15 percent depending on grape variety, yeast strain, and cellar temperature. For a winery pressing 80 tonnes of grapes at an average grape cost of €1.20/kg, that is €96,000 in raw material — and untracked losses of 5-12 percent mean €4,800-11,500 in value disappearing without documentation. Most small wineries in Bordeaux, Rioja, Tuscany, or the Mosel record harvest weight and bottling output but skip the intermediate steps: free-run juice yield, press yield, racking losses, fining losses, and filtration losses. Without this data, blend costing is guesswork.
How AskBiz connects the cellar pipeline#
Upload your harvest records (variety, vineyard block, kg received, sugar level), tank-by-tank fermentation logs (volume in, volume after pressing, volume after racking), and bottling records (litres filled, bottles produced). AskBiz calculates loss percentages at each stage and assigns accurate per-litre costs to every wine in your cellar. Ask: 'What is my true cost per bottle for the 2025 Merlot versus the 2025 Cabernet blend?' and get a breakdown that includes grape cost, proportional fermentation loss, oak ageing cost (if applicable), and bottling cost — not just a rough average.
Blend costing with multiple components#
When you blend three varieties from different vineyards — say 60 percent Tempranillo at €0.95/kg, 25 percent Garnacha at €0.80/kg, and 15 percent Graciano at €1.40/kg — each component has different fermentation loss rates. AskBiz weights the true cost per litre of each component after losses, so your blend cost reflects reality: the Graciano may only be 15 percent of volume but 22 percent of cost once its higher loss rate is included.

Real scenario: a family winery in the Languedoc#
Sophie runs a 12-hectare estate producing 65,000 bottles across six cuvées. She priced her rosé at €7.50 retail believing her cost was around €2.80 per bottle. After uploading three vintages of cellar data to AskBiz, the analysis revealed: her rosé saignée method was losing 18 percent of volume (higher than the 10 percent she assumed), direct pressing of Grenache yielded 62 litres per 100 kg versus the 70 she budgeted, and oak chip costs for her mid-range red were €0.35 per bottle — not the €0.18 she estimated because she was using chips faster than she tracked. True cost per bottle for the rosé was €3.45, leaving just €1.05 margin after distributor discount — barely viable. AskBiz recommended either raising the price to €8.90 or switching to direct pressing (lower loss) for the rosé. She chose direct pressing, cutting losses to 9 percent and bringing cost to €2.90, restoring a healthy €1.60 margin.
Excise and duty compliance#
EU wine excise duties vary by country (€0 in some, up to €3.50/litre in Scandinavian markets). AskBiz factors in excise, VAT, and transport costs by destination market so you see true margin per bottle per market — essential when deciding whether to sell domestically, export to Germany, or target the Nordic premium segment.
People also ask
How much wine is lost during fermentation?
Typically 5-15 percent depending on variety and winemaking method. AskBiz tracks loss at each cellar stage so you know exactly where volume disappears and can cost your wines accurately.
How should a small winery calculate cost per bottle?
Include grape cost, fermentation and racking losses, oak or additive costs, bottling, labelling, and excise. AskBiz automates this calculation from your cellar records.
Can AskBiz help wineries with blend costing?
Yes — it weights each component by its true post-loss cost per litre, so multi-variety blends are costed accurately rather than using rough averages.
Our team combines expertise in data analytics, SME strategy, and AI tools to produce practical guides that help founders and operators make better business decisions.
