The 7 best cheese to buy at Trader Joe's, according to a cheese expert

There's a key difference between authentic feta cheese from Greece and American-made feta: the authentic kind is made exclusively with sheep or goat milk. Thorpe said most of the feta we buy in America comes from cow milk and is radically different than the real thing.

Trader Joe's Authentic Greek Feta is made from sheep's milk and packed in brine.

"It's the real deal and it's so much better than cow's milk feta," Thorpe said. "The price is comparable to most supermarket feta or maybe $1 more per unit."

Break out this decadent brie-like cheese at your next party and watch it quickly disappear. Added cream gives it a rich, buttery texture that pairs perfectly with crusty bread or crackers.

For snacking, remove this cheese from the fridge ahead of time to allow it to soften.

Everyone knows the cheese staples like cheddar, mozzarella, and parmesan. Thorpe said Trader Joe's excels at helping customers take the next step up from these supermarket basics — a concept she calls "Cheese 201."

The Unexpected Cheddar is a perfect example. It's smooth and creamy like aged cheddar, but with a sweet-and-salty, nutty bite. Trader Joe's shoppers have ranked it their favorite cheese in the store for the past five years in a row, the company said.

Thorpe said the price tag is equally impressive.

"It's great for a dinner party spread, but you can also put it in your kid's lunch and you're not going to break the bank," she said.

Gruyere is a cheese from Switzerland that's name protected, similar to the denomination of champagne for sparkling wine made in the Champagne region of France. It's aged with a different process than the Swiss you pick up at the deli counter, and usually aged for six months or longer.

Thorpe said this is another example of the 'Cheese 201' category where Trader Joe's shines.

"If you're new to the world of cheese, you may not know the difference between, say, your standard block of Swiss cheese and Gruyere," she said. "Trader Joe's does a good job representing these fundamentals."

Most cheese lovers are familiar with young gouda, the mild, semi-soft cheese that typically has a red wax coating. You might not be as familiar with aged gouda.

Produced in the Netherlands, Trader Joe's 1,000 Day Gouda is similar in makeup to parmesan, with a crunchy crystalline texture and a butterscotch-like flavor.

"You can grate it like parmesan, pair it with big red wines, and it's awesome on a cheese board," Thorpe said.

It will set you back around $12 or $13 per pound.

Don't let the prices per pound give you sticker shock. Thorpe said if they seem high to you, it's probably because you're not used to seeing cheese priced by the pound. If you typically pay around $5.99 for a block of cheese from the grocery aisle (which is usually 8 ounces), that's the same as paying $12 per pound.

"I always, always have Parmigiano-Reggiano in my refrigerator," Thorpe said.

Flavorful, complex, and great for snacking, Parmigiano-Reggiano is made exclusively in Italy. This isn't your supermarket parmesan. In fact, the European Union's highest court has laid out strict requirements for how this cheese can be made and labeled in countries within the EU.

Characterized by its granular texture and lengthy aging process, Parmigiano-Reggiano is best enjoyed in freshly grated form over pasta dishes or as a standalone snack. Trader Joe's stocks a version that retails for about $15 per pound.
