Parmesan Cheese vs. Grana Padano

Both Parmesan cheese and Grana Padano are hard Italian cheeses made from cow's milk.

Parmesan Cheese vs. Grana Padano

They have some similarities but also key differences when it comes to their production methods, flavors, textures, uses, and more.

Where They're Made

Parmesan cheese can only be made in a specific region of Italy defined by Parmigiano-Reggiano's protected designation of origin (PDO). This includes the Italian provinces of Parma, Reggio Emilia, Modena, and parts of Mantua and Bologna. Grana Padano has a much larger, less strict geographic area for production. Its PDO region includes Piedmont, Lombardy, Trentino-Alto Adige, Emilia Romagna, Veneto, and parts of Mantua.

So Parmesan is made in Emilia-Romagna mainly while Grana Padano stretches across 5 regions from Piedmont to Veneto. The size and variance across Grana Padano's sizable production area leads to wider variation in its flavors.

Key Takeaway: Parmesan comes from a smaller region while Grana Padano is produced over a very large area of Northern Italy.

Milk and Feed Differences

Cows that produce milk for Parmigiano-Reggiano can only eat grass and cereals grown in the designated production area. Grana Padano cows, on the other hand, get 50% of their diet from grains not tied to any geographic restrictions.

This affects the cheese's taste and texture. Parmesan takes on those grassy, nutty flavors from the cows' grass-only diet. Grana Padano has a milk that's slightly fattier and sweeter thanks to the supplemental grains thrown into the cows’ feed.

Production Process and Aging Time

Parmigiano-Reggiano uses a mix of whole milk from the morning milking and partly skimmed milk from the prior evening's milking. The evening milk is kept cool overnight to allow the fat to separate before cheesemaking begins. Grana Padano starts with the raw milk from one or two daily milkings that is only partially skimmed.

So Parmesan starts with a semi-skimmed base while Grana Padano milk is less manipulated before cheesemaking starts.

A key difference comes in the aging time. Parmigiano-Reggiano ages a minimum of 12 months while Grana Padano only requires 9 months to be sold. The longer aging gives Parmesan a stronger, more complex nutty and salty flavor. It also makes the texture drier and crumblier. Grana Padano is creamier in texture due to its younger age.

Key Takeaway: Parmesan ages longer, creating a stronger flavor and crumblier texture compared to the younger, creamier Grana Padano.

Use of Preservatives

No preservatives are allowed in traditional Parmigiano-Reggiano production. However, Grana Padano does permit the preservative lysozyme during processing. This enzyme occurs naturally in egg whites, human tears, and other places. Allowing lysozyme helps Grana Padano avoid spoilage issues during the shorter 9+ month aging period.

Fat Content

Given the milk differences and shorter aging time, Grana Padano winds up with a lower fat content than Parmigiano-Reggiano. Grana Padano offers a more delicate, subtle flavor as a result. Parmesan packs a stronger, fuller-bodied punch in terms of taste.

Crystals and Texture

Both Parmesan and Grana Padano develop tyrosine crystals as they age. These white specks add a signature crunch and indicate the cheese's maturity level. However, the longer aging period for Parmigiano-Reggiano means more time for these grana crystals to accumulate and grow.

So authentic Parmigiano-Reggiano winds up with a trademark gritty, crumbly texture and loads of shiney crystals running throughout. Grana Padano still gets grainy with age but remains a bit creamier and smoother even when fully aged.

Flavor Profiles

Parmigiano-Reggiano offers a range of flavors that intensify over the 12+ month aging time. Young wheels taste prominently of milk. As it ages, nutty, fruity citrus flavors develop along with notes of hazelnut. The end result is a complex medley of tastes.

Grana Padano has a sweeter, softer flavor at all ages. It embodies more delicate, buttery qualities along with hints of broth. Experts can detect traces of steamed vegetables or other subtler notes. The grain-fed diet and young age stop short of developing the same boldness as Parmesan.

Key Takeaway: Parmesan has a bigger, bolder flavor profile thanks to its longer aging while Grana Padano retains a sweeter, subtler taste.

So in terms of sheer taste intensity, Parmigiano-Reggiano beats out Grana Padano by a good margin, especially when both are fully aged. However, Grana Padano's smoothness and subtlety have their place in cooking as well.

Uses in the Kitchen

Thanks to its rich flavor that keeps intensifying with age, Parmigiano-Reggiano gets frequently grated atop pastas, risottos, salads and more to finish dishes. Its crumbly texture also makes it perfect for this role. Grana Padano melts a little better thanks to its creaminess, so it often gets called for in cooked sauces and other dishes instead of just a finishing sprinkle.

Parmesan also stands up beautifully all on its own with wine, fruit, cured meats, etc. Its ambrosial decadence deserves to take center stage. Grana Padano complements other ingredients better than shining solo.

Price Differences

Grana Padano costs notably less than the famous Parmigiano-Reggiano. Supply plays a role as Grana Padano gets produced in much higher quantities each year. But the lower prices also come from factors like the less restrictive PDO rules, grains in cattle feed cutting costs, shorter aging periods, and larger permitted batch sizes during cheesemaking.

Parmigiano-Reggiano also faces extremely high rejection rates, upwards of 20% of all wheels produced. This drives up costs considerably. Mandatory inspections ensure that only the best cheese meets the high Parmigiano-Reggiano standards and gets the fire brand marking those famous two names around the rind.

Health Benefits

Both Parmesan and Grana Padano offer tremendous nutritional value. They provide ample protein, good fats, calcium, and other vital nutrients. As hard aged cheeses, they contain very little lactose making them easier to digest for those sensitive to dairy. The longer aging also increases Parmigiano-Reggiano's glutamine levels, offering digestive and gut health benefits.


Grana Padano holds the distinction of being the best-selling PDO cheese globally. It edges out Parmesan in worldwide popularity thanks to that lower price point and milder, accommodating flavor.

However, Parmigiano-Reggiano enjoys greater prestige around the globe as one of Italy's most famous products. It often gets called the "king of cheese" for its unparalleled depth and complexity after those long months of aging. Most cheese experts and aficionados rank it higher than Grana Padano in terms of quality and taste.


Can you use Grana Padano instead of Parmesan?

Yes, Grana Padano makes an acceptable stand-in for Parmesan in most recipes. You'll notice some flavor differences but it will largely achieve a similar effect thanks to the hard texture, saltiness, and sprinkle-friendly grated form.

What's the difference between Parmesan and Parmigiano Reggiano?

Parmigiano-Reggiano is the actual Italian name with PDO status made to specific regional standards. "Parmesan" is often used generically, especially in other countries, to describe similar Italian hard grating cheeses. But authentic Parmigiano-Reggiano offers a bolder, better flavor thanks to regional milk, aging protocol, and careful quality control.

Is Parmesan better than Grana Padano?

In terms of sheer depth and complexity of flavor, Parmesan beats out Grana Padano by a clear margin, especially when both are fully aged. But Grana Padano costs less and offers other positives like a nice melting texture. Ultimately personal preference dictates which one suits your tastes better.

Can you eat Grana Padano rind?

Yes, Grana Padano rind gets enjoyed in cooking applications to add flavor. Finely grate it into soups, stews, stocks, and sauces. As it melts, the rind delivers a boost of umami savoriness. Just be sure to remove any big chunks before serving the finished dish if you don't want to bite into large pieces.


Parmigiano-Reggiano and Grana Padano share ancestry as iconic grainy Italian cow's milk cheeses with PDO status. But key differences in aging time, preservatives, cattle feed, milk handling, and production regions create noticeable contrasts between them.

Parmesan costs more but rewards buyers with an unrivaled intensity and nuance of flavor. It makes the perfect finishing touch thanks to that hard, crumbly texture with distinctive crunch from all those little protein crystals.

Grana Padano charms with milder milky notes and a more accommodating creamy character. It melts beautifully into all kinds of cooked foods. Plus that lower price tag keeps it accessible for regular everyday enjoyment on pastas and pizzas.
