Question 1

True or false: The iconic holes in Gruyère are caused by carbon dioxide bubbles from propionic acid bacteria.

Accepted Answer

False. Holes are typical of Emmental, not Gruyère. Gruyère is a firm, dense cheese with few or no eyes.

Question 2

True or false: Authentic Gruyère must be aged for a minimum of 12 months to earn its AOP label.

Accepted Answer

False. The minimum aging for AOP Gruyère is only 5 months; longer aging is optional for stronger varieties.

Question 3

True or false: Gruyère is made exclusively from the raw milk of cows that graze on Alpine pastures.

Accepted Answer

True. AOP rules require milk from cows fed only grass or hay, with no silage, and summer grazing on alpine meadows.

Question 4

True or false: Gruyère has been produced in the same region of Switzerland since at least 1115 AD.

Accepted Answer

True. Historical records confirm Gruyère cheese-making dates back to the 12th century in the canton of Fribourg, Switzerland.

Question 5

True or false: Gruyère is lactose-free because the aging process naturally breaks down all lactose.

Accepted Answer

False. Aged Gruyère contains trace lactose, often tolerated, but it's not completely lactose-free for sensitive individuals.

Question 6

True or false: During aging, Gruyère wheels are regularly brushed with salt brine to develop the rind.

Accepted Answer

True. This traditional process, called 'frottage,' involves rubbing the wheels with brine to encourage bacterial growth and flavor.

Question 7

True or false: Swiss law permits Gruyère to be produced in neighboring France under the same name.

Accepted Answer

True. Since 2001, French Gruyère (from Franche-Comté) is legally recognized alongside Swiss, though with different AOP rules.

Question 8

True or false: A single wheel of traditional Gruyère can weigh up to 45 kilograms (100 pounds).

Accepted Answer

False. Gruyère wheels typically weigh 25–35 kg (55–77 lb); 45 kg would be unusually large for this cheese type.
