Kernhem is a rich Dutch washed-rind cheese developed by the Nederlands Instituut voor Zuivelonderzoek in Ede. It combines a reddish aromatic surface with a creamy, mildly piquant paste, so it offers red-rind character without the force of many stronger washed cheeses.
The “60+” on a Dutch specification refers to fat in dry matter. It does not mean that 60 percent of the cheese you eat is fat.

Kernhem Is a Designed Dutch Red-Rind Cheese
Kernhem is made from pasteurized cow's milk and formed as a small wheel. Its rind is washed during maturation, creating a red-brown surface around a soft to semi-soft yellow paste.
It is a modern Dutch cheese, not a variety of Gouda. The wash, high richness, sticky edge, and mild savory finish give it a separate identity.
The Nederlands Instituut voor Zuivelonderzoek, commonly known as NIZO, developed Kernhem in Ede. Its name comes from the Kernhem estate associated with the institute, not from a centuries-old village recipe.
The Dutch dairy research institute known as NIZO developed the cheese in Ede.
It was named for the Kernhem estate where the institute was based rather than for an old town recipe.
This origin matters because Kernhem was designed as a repeatable rich cheese with a controlled red rind. Stories that reduce it to a lucky overheated batch are less useful than the documented institute and current product specifications.
That designed origin also explains the unusually precise current specification. Milk treatment, fat class, nutrition, rennet, allergen details, wheel format, and rind style can all be checked instead of inferred from folklore.
60+ Measures Fat in Dry Matter, Not the Whole Bite
“60+” expresses fat as a proportion of the cheese's dry matter after water is excluded.
Kernhem retains substantial moisture, so its total fat by weight is lower.
The current Treur Kaas specification lists 38 grams of total fat per 100 grams. Use the package in front of you for nutrition because formulations and moisture can differ between suppliers.
A simple way to read the label is to imagine removing the water first. The 60+ class describes the share of fat in what remains, while the nutrition panel describes the cheese as sold, water included.
This distinction matters when comparing Kernhem with a drier cheese. Two products can carry similar dry-matter classes yet deliver different total fat per 100 grams because their water content is not the same.
Read 60+ as a composition class, not a serving recommendation and not 60 grams of fat per 100 grams of cheese.
The Red Rind Creates an Edge-to-Center Gradient
The washed surface smells more aromatic and tastes more savory than the center.
Directly beneath it, the paste becomes softer and slightly tacky before the interior does.
A whole bite moves from lightly piquant rind to cream and nuts. Include a narrow strip of rind first, then adjust the proportion rather than judging the cheese from the surface alone.
The surface wash keeps the rind biologically active during maturation. Its enzymes begin breaking down the paste from the outside, which is why the band under the rind can feel sticky and yielding while the center still cuts cleanly.
A larger rind proportion makes a small piece taste more savory. Cut a broad wedge when you want more mild center, or a narrow rind-to-center slice when you want the full red-rind progression.
Ripeness Changes the Best Way to Use the Piece
A young piece has a resilient center and a restrained aroma. A ready wedge yields under light pressure and shows a creamy band beneath a tacky, intact rind.
Pass over a piece with a dry dark gap at the rind, leaking paste, or dominant ammonia. A retailer date helps, but the condition of a cut wedge tells you more about its recent handling.
A resilient young center works for neat lunch slices and small cubes. A yielding piece gives more aroma and a creamier mouthfeel on a board, but it also warms and collapses faster.
Check the cut face before judging the rind alone. A tacky red exterior is expected, while a dry separation line between rind and paste suggests the wedge has lost moisture after cutting.
Acid and Crunch Keep the Rich Paste in Focus
Give it about 30 minutes outside the refrigerator so the center loosens.
Rye bread, cornichons, and crisp pear provide grain, acid, and fresh sweetness against the rich paste.
A dry white wine with enough acidity works better than a heavily tannic red. The goal is to clear the fat and leave the mild red-rind savoriness intact.
Serve rind-to-center slices so each portion contains the piquant edge and creamy middle. If the rind dominates, make the next slice wider rather than removing every trace of the surface.
Moderate Heat Turns Kernhem into a Savory Soft Layer
Its moist, rich paste softens readily over potatoes, chicory, mushrooms, or toast.
Cut small pieces so the rind flavor spreads instead of collecting in one strip.
Add it late or use moderate oven heat. Prolonged high heat can separate a high-fat paste and erase the subtle contrast between rind and center.
Chicory and mushrooms work because their bitterness or earthiness can meet the rind, while potatoes and toast give the soft paste structure. Kernhem is less useful when a recipe needs an elastic cheese pull rather than a creamy coating.
Distribute small pieces across the dish instead of laying one rind-heavy strip in the center. That spreads both the fat and the savory surface flavor before the paste loosens.
One Unusual Allergen Detail Makes the Label Essential
The current Treur Kaas sheet lists pasteurized cow's milk and vegetarian rennet. It also lists lysozyme E1105 derived from egg, an unusual detail that matters to someone with an egg allergy.
Another seller's formulation may differ, so check the current ingredient and allergen panel. Wrap the cut cheese in parchment or cheese paper, place it in a loose container, and replace damp wrapping before the rind turns slimy.
Egg-derived lysozyme is easy to miss if you look only for the milk allergen. Someone avoiding egg needs the formulation on the actual package, even though the cheese uses vegetarian rennet.
Keep the rind from touching pooled moisture in the container. A breathable inner wrap and a loose outer box protect the cut face while containing aroma without sealing a damp surface against plastic.
Kernhem FAQ
SOURCES & REFERENCES
Yes. The current Treur Kaas specification uses vegetarian rennet.
Usually about eight to ten weeks, which is short enough to keep the paste soft and the rind character moderate.
No. It offers red-rind character without the force of many stronger washed cheeses, and the paste itself stays mild, creamy and only lightly piquant.
