Cheese maker Jacques Murith leans over a glowing vat of whey as he prepares serac, a soft, ricotta-like cheese.
For five generations his family has worked in this picturesque corner of Switzerland to also produce another, more famous dairy product - Gruyere. The firm and slightly nutty-flavoured cheese is both tricky and time-consuming to make, and from mid-May to mid-October the Muriths devote almost all their time to the process.

Each wheel of the Muriths’ cheese weighs 25-40 kilograms (55-88 lbs) and takes a minimum of six months to mature. Every year, the family produces around 200 of the hefty slabs from the unpasteurised milk of their dairy herd.
The business has long been passed down the generations, and now Jacques Murith is preparing to hand it on to his 23-year-old son Alexandre, pictured here pulling a trolley full of Gruyere through a ripening cellar.

The family's farm and dairy are based in the mountainous landscape near the town of Gruyeres - the area from which their cheese takes its name.

Cow’s milk is turned into Gruyere through a delicate process, during which cultures and enzymes are added to huge vats of milk, which is heated, stirred, moulded and matured. All sorts of factors can affect the final product, from the temperature of the milk in the morning to the weather outdoors.
