EU Flour Mill: Grain-to-Flour Extraction Rate and By-Product Revenue with AskBiz

Extraction Rate Is the Core Metric for EU Flour Mills#

A small EU flour mill processing 5,000 to 30,000 tonnes of wheat annually operates in one of the most margin-compressed food manufacturing sectors. Wheat purchase price — typically €220–€300 per tonne for milling-grade wheat in the EU — represents 75–85% of operating cost. The extraction rate — kilograms of flour produced per 100 kilograms of wheat — determines how efficiently that cost converts to sellable product. White flour extraction runs 72–76%, wholemeal 90–95%, and speciality flours (tipo 00, strong bread flour) 65–72% depending on specification. A mill processing 15,000 tonnes of wheat at an average extraction rate of 75% produces 11,250 tonnes of flour and 3,750 tonnes of by-products (bran, middlings, wheat germ). A 1% improvement in extraction rate yields an additional 150 tonnes of flour worth €45,000–€60,000 at wholesale prices of €300–€400 per tonne — often the difference between profit and loss for a small mill.

How AskBiz Tracks Extraction by Grain Lot and Flour Type#

AskBiz lets the miller log each production run with wheat lot origin, protein content, moisture level, and the flour types produced with their weights. A mill buying French wheat at 12.5% protein and 13% moisture might extract 76% white flour, while Polish wheat at 11.8% protein and 14.5% moisture yields only 73%. Over 20 to 30 grain lots, AskBiz builds a dataset linking wheat specifications to extraction outcomes. The miller can see that high-protein wheat from specific regions consistently yields 2–3% more flour despite costing €10–€15/tonne more — a premium that pays for itself when flour sells for €350/tonne. This data also supports purchasing decisions: when offered a discounted lot of lower-specification wheat, the miller can calculate whether the price saving compensates for the expected extraction penalty.

By-Product Revenue and Its Impact on Overall Mill Profitability#

The 20–28% of wheat that does not become white flour is not waste — it is bran, middlings (also called shorts or semolina middlings), and wheat germ, each with distinct markets and values. In the EU, wheat bran sells for €120–€180 per tonne to animal feed compounders, middlings for €140–€200 per tonne, and wheat germ for €300–€600 per tonne to food and supplement manufacturers. A mill producing 3,750 tonnes of by-products annually at a blended average of €155/tonne generates €581,000 in by-product revenue — equivalent to roughly 15% of total mill revenue. AskBiz tracks by-product output per production run and links it to actual sales prices, showing the miller that last month's bran was sold at €135/tonne while the 3-month average was €158/tonne. This prevents systematic under-selling to feed merchants who may exploit the mill's desire to move by-products quickly.

True Margin Per Tonne of Wheat Processed#

AskBiz calculates the full economics per tonne of wheat processed: wheat cost, milling energy (€8–€14 per tonne for electricity), labour (€4–€8 per tonne for small mills), packaging (€3–€6 per tonne for 25kg bags or €1–€2 for bulk), maintenance allocation (€2–€4 per tonne), and transport. Against this, it tallies revenue from all flour types and by-products. A typical calculation might show: wheat cost €265, processing costs €22, total cost €287 per tonne input. Revenue: 0.75 tonnes flour at €360/tonne = €270, plus 0.25 tonnes by-products at €155/tonne = €39 — total revenue €309. Gross margin: €22 per tonne or 7.1%. At 15,000 tonnes annual throughput, that is €330,000 gross margin. AskBiz shows this per-tonne calculation updated with each production run, making it immediately visible when a wheat lot or flour type drops below the profitability threshold.

Speciality Flour as a Margin Improvement Strategy#

Small EU mills increasingly differentiate by producing speciality flours — spelt, einkorn, ancient grains, stone-ground, and locally-branded heritage varieties — that command €500–€1,200 per tonne versus €300–€400 for standard white flour. A mill dedicating 20% of capacity to spelt flour at €700/tonne and einkorn at €950/tonne can increase blended flour revenue by €80–€120 per tonne of total output. AskBiz tracks the margin contribution of each flour type separately, showing the miller that while spelt has a lower extraction rate (68% versus 75% for standard wheat), its higher selling price more than compensates — generating €35 per tonne of input versus €22 for standard milling. This data supports decisions about how much capacity to shift toward speciality production and which grain varieties to source for the next season, with lead times of 6 to 12 months for contracted growing.
