How it's made
Milk Sourcing & Standardization
Raw cow/goat/sheep milk is collected, tested, pasteurized (most cheese) and standardized for fat/protein.
Coagulation
Starter cultures acidify the milk and rennet (chymosin) coagulates it into curds — the enzymatic step at the heart of cheesemaking.
Curd Processing
Curds are cut, cooked, drained, milled and salted; texture is developed (cheddaring, stretching for mozzarella, etc.).
Pressing & Forming
Curd is pressed into molds/wheels/blocks and brined or dry-salted.
Aging & Packaging
Cheese is ripened (days to years) under controlled temperature/humidity with specific cultures, then cut and packaged.

dsm-firmenich AG (Kaiseraugst, Basel-Land, Switzerland; formed by merger of DSM NV Netherlands and Firmenich SA Geneva, completed May 2023; combined revenue ~€12B of which fragrance ~€3-4B) is the world's third-largest fragrance company. Firmenich (private, Geneva; founded 1895 by Philippe Chuit and Martin Naef) was the world's largest private fragrance house and the only major fragrance company to remain independent until the DSM merger. Firmenich's fragrance heritage includes Chanel No. 5 (Firmenich supplies the fragrance compound to Chanel — one of the most carefully guarded commercial relationships in the fragrance industry; the Chanel No. 5 formula is a Firmenich-originated formula from 1921). DSM contributed nutrition, health, and biosciences (vitamins, carotenoids, animal feed enzymes) to the merger. The combined dsm-firmenich operates manufacturing at Geneva (Switzerland), Haverhill (UK), Neuvy-sur-Barangeon (France), and Florham Park (USA). The Firmenich name is retained in the merged entity's fragrance operations branding.

Fonterra Co-operative Group Limited (Auckland, New Zealand; farmer-owned cooperative; NZX: FCG; FY2024 revenue ~NZ$22B; ~10,000 farmer-shareholders; CEO Miles Hurrell) is the world's largest dairy exporter and the dominant single player in global dairy commodity trade. Fonterra collects approximately 22 billion litres of New Zealand milk per year — roughly 90% of all milk produced in New Zealand. That milk is processed into commodity dairy ingredients: whole milk powder (WMP), skim milk powder (SMP), anhydrous milk fat (AMF), butter, and cheese. New Zealand produces approximately 3% of world milk by volume but accounts for approximately 30% of global dairy trade in milk solids — because New Zealand's pasture-based system produces surplus far beyond domestic consumption, and all of it is exported. Fonterra operates the Global Dairy Trade (GDT) auction — a Fonterra-controlled biweekly online auction that sets benchmark prices for WMP, SMP, butter, AMF, and cheddar globally. GDT prices are the benchmark against which virtually all international dairy commodity contracts are priced. Fonterra's market position means that New Zealand weather events (droughts, floods), New Zealand government milk price regulation (the Fonterra Milk Price Manual is government-supervised), and Fonterra's processing capacity constraints propagate directly into global dairy commodity prices. When Fonterra revises its forecast milk price (Farmgate Milk Price), the New Zealand dollar moves — Fonterra is so large relative to the NZ economy that the cooperative is a macro driver. Fonterra's primary processing facilities are concentrated in the Waikato (North Island, near Hamilton), Taranaki (North Island, near New Plymouth, including Whanganui), and Canterbury/South Canterbury (South Island — Studholme, Clandeboye, Edendale).

Dairy Farmers of America, Inc. (Kansas City, Missouri; farmer-owned cooperative; FY2023 revenue ~$21B; ~11,500 dairy farmer-members in 48 US states; CEO Darin Karst) is the largest US dairy cooperative and the single largest processor of US milk — collecting approximately 30% of all US raw milk production (approximately 67 billion pounds of milk per year). DFA handles milk through a network of 50+ processing plants across the US — including cheese plants (DFA is the largest US cheese producer), butter and powder facilities, fluid milk bottling plants, and specialty dairy ingredient plants. DFA's manufacturing includes American-type cheese (cheddar, colby, monterey jack), cream cheese, butter, dried milk powders, and whey proteins. DFA also operates as a milk marketing cooperative — acting as a balancer for regional milk supply, moving surplus milk between regions and processing it into storable commodities (butter, powder) when fluid milk demand is insufficient. DFA acquired the Dean Foods assets in 2020 following Dean Foods' bankruptcy (Dean Foods was the largest US fluid milk bottler; its bankruptcy reflected the long-term decline in US fluid milk consumption — down ~25% since peak). DFA's acquisition of Dean Foods gave it a dominant position in US fluid milk bottling at the same moment fluid milk demand was structurally declining — an ironic market position. DFA is the primary counterparty to US dairy farmers in most US regions.

Groupe Lactalis (Laval, Pays de la Loire, France; privately owned by the Besnier family — Emmanuel Besnier, CEO since 2000, grandson of founder André Besnier; estimated FY2023 revenue ~€28B — making it the world's largest dairy company by revenue) is the most opaque major player in global dairy. Lactalis is entirely private (no public reporting obligation), controlled by the Besnier family trust, and rarely communicates financial details. Yet Lactalis processes milk across 26 countries, operates 260+ production sites, employs 85,000+ people, and owns the world's most recognized dairy brands: Président (butter — dominant French butter brand; also major globally), Galbani (Italian mozzarella and ricotta), Parmalat (UHT milk — a Brazilian-acquired brand dominant in Italy, Brazil, South Africa; Lactalis acquired Parmalat in 2011 for €3.4B), Lactel (French UHT milk), Bridel (French butter), Société (Roquefort cheese), Valbreso (French feta), and Stonyfield Organic (US yogurt, sold to Lactalis from Danone 2017). Lactalis sources milk from thousands of contracted farmers across France, Italy, and other EU countries — it does not own farms but signs long-term milk purchase contracts (Lactalis's mill price-setting power vis-à-vis French dairy farmers has been a subject of regulatory investigation). Lactalis's infant formula business became a global crisis in 2017-2018 when its Craon, France, factory was identified as the source of Salmonella Agona contamination in infant formula — affecting 35+ countries, forcing the largest infant formula recall in history, and resulting in French criminal investigation. The Craon factory had a known Salmonella problem in its construction since 2005 — Lactalis's internal documentation shows awareness predating the outbreak by 12 years.

FrieslandCampina N.V. (Amersfoort, Gelderland, Netherlands; farmer-owned cooperative Zuivelcooperatie FrieslandCampina U.A.; Euronext: CFCPA; FY2023 revenue €13.8B; ~12,000 farmer-members in Netherlands, Germany, and Belgium) is the second-largest dairy cooperative globally by revenue and the largest dairy company in the Netherlands and Germany by milk processing volume. FrieslandCampina collects approximately 10 billion litres of milk per year from its members. Product portfolio: Dutch Lady (Southeast Asia liquid milk — dominant market share in Malaysia, Vietnam, Nigeria), Friso (infant formula — premium Dutch-origin infant formula for China and Hong Kong; 'Friso Gold' is positioned as a premium Dutch-made formula trusted by Chinese parents post-2008 melamine scandal), Campina and Chocomel (branded consumer dairy in Netherlands), Milner cheese (Dutch Gouda), and industrial ingredients. FrieslandCampina's Friso infant formula business in China is a strategically significant business unit — it capitalizes directly on Chinese distrust of domestic infant formula brands following the 2008 melamine scandal (San Lu Group). FrieslandCampina also processes milk from German members through its German subsidiary DMK Deutsches Milchkontor (not owned, but closely connected). The company's geographic concentration in the Netherlands (one of Europe's most intensive dairy farming regions) creates aggregate biosecurity risk — a major animal disease event in Dutch dairy farms would simultaneously affect milk supply and FrieslandCampina's processing utilization.

Arla Foods amba (Viby J, Aarhus, Central Denmark; farmer-owned cooperative; FY2023 revenue €13.7B; ~8,800 farmer-owners in Denmark, Sweden, Germany, UK, Netherlands, Belgium, Luxembourg) is the largest dairy company in Scandinavia and the largest dairy cooperative in Europe by owner-farmer count. Arla collects approximately 14 billion litres of milk per year across its six-country member base. Key brands: Lurpak (butter — the world's most recognized butter brand, dominant in UK and Middle East; Lurpak is the gold standard for premium block butter in UK supermarkets, holding a 40%+ value share of UK branded butter), Arla (corporate brand — organic milk, fresh dairy, cheese across Europe), Castello (Danish cheese), Puck (cream cheese dominant in Middle East and North Africa), and Cravendale (UK filtered milk). Arla's UK milk collection (via Arla UK, formerly Northern Foods dairy assets) makes it the largest dairy company in the UK by processing volume. Arla has faced periodic conflicts with UK supermarkets over farmgate milk pricing — most notably the 2012 British dairy farmer protests ('Dairy Crisis') when farmgate prices fell below cost of production. Arla's global ingredient manufacturing (milk powders, AMF) competes directly with Fonterra in commodity markets. Arla has made significant sustainability commitments (climate neutral by 2050) — its Scandinavian farmer-owners face increasing carbon regulation on methane emissions from dairy cattle.

Saputo Inc. (Saint-Laurent, Montreal, Quebec, Canada; TSX: SAP; FY2024 revenue ~CAD$17.8B; founded 1954 by Giuseppe Saputo, an Italian immigrant cheesemaker; CEO Lino Saputo Jr., grandson of founder) is the world's fourth-largest dairy processor by revenue, with operations in Canada, USA, Australia, Argentina, and the UK. Saputo's Canadian operations process Quebec and Ontario milk into mozzarella (dominant Canadian pizza cheese supplier), ricotta, and specialty cheeses. In the US, Saputo is a major cheese and dairy ingredient producer (acquired Lucerne Foods dairy from Safeway, Murray Cheese, Frigo, and Treasure Cave brands). In Australia, Saputo acquired Murray Goulburn's dairy assets in 2018 (after Murray Goulburn — Australia's largest dairy cooperative — collapsed in a milk pricing scandal) and owns the Devondale, Coon, and Cracker Barrel cheese brands. Saputo's acquisition of Murray Goulburn's assets made it the largest dairy processor in Australia, handling approximately 30% of Australian milk. Saputo's global expansion reflects a consolidation strategy: acquire distressed dairy processors (Murray Goulburn, Warnambool Cheese), absorb milk supply, and integrate into Saputo's North American cheese processing and distribution infrastructure.

Abbott Nutrition (Abbott Park, Illinois; division of Abbott Laboratories NYSE: ABT; FY2023 Abbott total revenue ~$20B; Nutrition segment ~$8B) is the largest US infant formula manufacturer by market share, producing Similac (the #1 US infant formula brand), Similac Pro-Advance, Similac for Supplementation, Similac Alimentum (hypoallergenic — elemental formula for cow's milk protein allergy), Pediasure (pediatric nutritional supplement), and Ensure (adult nutritional supplement). Abbott's Sturgis, Michigan facility — the primary US Similac manufacturing plant — became the center of the 2022 US infant formula shortage crisis. In February 2022, Abbott voluntarily recalled Similac, Alimentum, and EleCare powdered infant formulas produced at Sturgis after FDA inspections found Cronobacter sakazakii contamination linked to four infant hospitalizations and two deaths. Abbott shut the Sturgis plant (which produced approximately 40% of all US powdered infant formula) for approximately 4.5 months (February to late June 2022). The simultaneous shutdown of the dominant US plant for the dominant US brand — in a market where import certification barriers prevent rapid substitution with foreign formula — produced a national infant formula shortage. US stores implemented purchase limits; WIC program (which covers approximately 50% of US infant formula purchases) faced allocation crises. The shortage lasted approximately 6-8 months before supply normalized. Abbott's Sturgis facility resumed production in June 2022 under a consent decree with FDA.

Abbott Nutrition (Abbott Laboratories) · Michigan
Abbott Nutrition's Sturgis, Michigan manufacturing facility — the primary production site for Similac powdered infant formula (the #1 US infant formula brand). Sturgis was the site of the 2022 US infant formula crisis: FDA inspections found Cronobacter sakazakii bacterial contamination; Abbott issued a voluntary recall in February 2022 and shut the plant for ~4.5 months. Because Sturgis produced approximately 40% of all US powdered infant formula, and because US infant formula import certification barriers prevented rapid foreign-source substitution, a single facility closure triggered a national infant formula shortage affecting millions of infants. The Sturgis facility resumed production in late June 2022 under an FDA consent decree with enhanced environmental monitoring requirements. The US infant formula market's extreme concentration (Abbott + Mead Johnson/Reckitt + Nestlé USA accounting for 80%+ of supply) and import barriers (WIC contract system, FDA foreign facility registration) created a structural fragility that the 2022 crisis exposed.
Arla Foods amba · Central Denmark
Arla Foods' global headquarters in Viby J (Aarhus municipality), Denmark — coordinating dairy ingredient manufacturing, brand management, and cooperative governance for ~8,800 farmer-owners across six countries. Arla's Danish processing facilities (Viby, Bislev, Holstebro) produce Lurpak butter, Danish feta (PDO Feta is Greek; Danish white cheese is a close competitor product), and dried ingredients. Arla's Danish operations are the origin of the Lurpak brand — the single butter brand that commands premium pricing globally and maintains dominant market share in UK, Middle East (Gulf Cooperation Council markets), and Scandinavia. Lurpak's brand equity is so strong that UK Tesco's 2022 decision to lock Lurpak behind a security tag due to butter theft generated international media coverage as a proxy for UK cost-of-living crisis severity.

Dairy Farmers of America (DFA) · Missouri
Dairy Farmers of America's Kansas City, Missouri headquarters functions as the nerve center for milk marketing, balancing, and cooperative governance for the largest US dairy cooperative (~11,500 farmer-members; ~30% of US milk). DFA doesn't operate a major manufacturing plant at HQ but coordinates milk movement, forward contracts, and balancing operations that determine how surplus regional milk is routed to butter/powder production. DFA's market reach is national: it operates cheese plants (DFA Cheese Company Wisconsin, Idaho), fluid milk facilities (former Dean Foods bottling plants across the US acquired in 2020 bankruptcy proceedings), and ingredient plants (whey protein, milk powders). DFA's balancing role in the US dairy market makes its cooperative decisions directly influential on farmgate prices paid to US dairy farmers across multiple regions.
Fonterra Co-operative Group Limited · Southland · dairy-processing
Fonterra's Edendale processing complex in Southland, South Island, New Zealand — the largest dairy processing site in the Southern Hemisphere by throughput. Edendale processes approximately 4.5 billion litres of milk per year from Southland and Otago farms (the most productive pastoral dairy land in New Zealand). Outputs: whole milk powder (WMP), skim milk powder (SMP), anhydrous milk fat (AMF), and butter. Edendale is the anchor facility for Fonterra's South Island milk collection and a critical node in global dairy commodity supply — its WMP output feeds directly into the Global Dairy Trade auction that sets global milk powder prices. Southland dairy farming depends on reliable water supply from rivers fed by Southern Alps snowmelt; drought events in Southland directly reduce milk intake at Edendale and flow through to GDT price movements globally.
FrieslandCampina N.V. · Friesland
FrieslandCampina's Leeuwarden facility in Friesland, Netherlands — in the historic heartland of Dutch dairy farming (the Friesian cow breed takes its name from this region). This facility handles consumer and ingredient dairy products for Northern European markets. Leeuwarden is FrieslandCampina's primary Dutch processing hub alongside its Workum and Borculo facilities. The Netherlands is the world's largest dairy exporter by per-capita volume — Dutch dairy exports exceed domestic consumption by 3:1. FrieslandCampina's Friesland-based infrastructure is the backbone of Dutch dairy exports to EU markets and the foundation of the Friso infant formula supply chain (Dutch-origin milk processed for Chinese premium infant formula market).
Lactalis Group (Groupe Lactalis) · Pays de la Loire
Lactalis's Craon facility in Pays de la Loire, France — the site of the 2017-2018 Salmonella Agona infant formula contamination crisis. The Craon factory (producing Picot and Milumel infant formula brands) was identified in December 2017 as the source of Salmonella contamination in infant formula distributed to 35+ countries. The recall was the largest infant formula recall in history — involving more than 12 million boxes of formula. French investigators subsequently established that Salmonella had been detected at the Craon facility as early as 2005 (a renovation created a persistent environmental contamination site in building infrastructure). Lactalis's internal records showed awareness of contamination risk long before the 2017 outbreak. Criminal charges were filed in France; the CEO was questioned by French authorities. The episode demonstrated that infant formula — a product with no acceptable risk threshold given its role as the sole nutrition source for vulnerable infants — can harbor contamination for years in factory infrastructure before causing a crisis.
