What Is Emmental?
Emmental is Switzerland's most recognizable cheese — and arguably the world's most imitated. Named after the Emme River valley in the canton of Bern, it has been produced in the region since at least the 13th century, with written records confirming its export trade by the 1540s. The wheels are enormous by necessity: a traditional Emmental weighs between 75 and 120 kilograms, a size that was historically required to justify the long journey to market.
The cheese carries AOC (Appellation d'Origine Contrôlée) protection in Switzerland under the designation Emmentaler AOP, meaning that authentic Swiss Emmentaler must be made from raw cow's milk in designated Swiss cantons. What gets sold globally as "Swiss cheese" or "Emmental-style" is largely an industrial imitation — usually milder, rubbery, and made from pasteurized milk. If you want the real thing, look for the Emmentaler AOP label and the distinctive cave-aged variety labeled Höhlenkäse, aged a minimum of 12 months in natural limestone caves.
Those famous holes — properly called eyes — are not a flaw but a carefully controlled feature. They form during the aging process when Propionibacter shermani bacteria consume lactic acid and release carbon dioxide, which becomes trapped inside the curd and forms hollow pockets.
Taste & Texture
Authentic Emmentaler rewards patience. Younger wheels (4–6 months) offer a mild, milky sweetness with soft grassy notes and gentle nuttiness. As aging progresses past 8 months, the flavor deepens considerably: richer butterscotch tones emerge alongside a pleasant sharpness, dried fruit complexity, and a long, warm finish. The oldest cave-aged examples develop a crystalline, almost crunchy texture near the rind, with an intensity that rivals Gruyère.
The interior is pale ivory to golden yellow, elastic but firm, and slices cleanly without crumbling. The rind is dry, golden-brown, and lightly brushed — edible but typically discarded.
How to Serve
Remove Emmental from the refrigerator at least 30 minutes before serving. At room temperature, its texture softens just enough to release its full aromatic profile. On a cheese board, slice it into thin planks or cubes — it doesn't need much accompaniment beyond a crisp apple, a few cornichons, and good mustard.
For cooking, Emmental is a workhorse. It melts with exceptional smoothness, making it the backbone of a classic Swiss fondue (always combined with Gruyère), a reliable filling for croque-monsieur, and an indispensable layer in French onion soup. It also performs beautifully gratinéed over vegetables or folded into quiche.
Emmental vs. Gruyère
| Feature | Emmentaler AOP | Gruyère AOP | |---|---|---| | Holes | Large, walnut-sized | Few or none | | Flavor | Mild, sweet, nutty | Stronger, earthier, more complex | | Aging | 4–18+ months | 5–24+ months | | Best use | Cheese boards, fondue base | Fondue, gratins, solo eating | | Texture | Firm, elastic | Dense, slightly granular |
Storage
Wrap Emmental in wax paper or cheese paper, then loosely in plastic wrap or store in an airtight container. It keeps well in the coldest part of your refrigerator (around 4°C / 39°F) for 3–4 weeks once cut. If a small spot of surface mold appears, simply trim 1cm around it — the cheese beneath remains perfectly safe. Never freeze Emmental; it shatters the texture and kills the nuance you paid for.
