How Do You Choose Quality Yoghurt and Dairy Products?

When choosing quality yoghurt and dairy products, the first thing to check is the production and expiry date printed on the package; a fresh product is usually still weeks away from that date, while items nearing expiry tend to turn up more often on discount shelves. The ingredient list should show only milk and culture (bacteria starter) for yoghurt, or simply "milk" as a single item for plain milk; additives such as starch, gelatin or milk powder are a sign that the texture is being propped up artificially.

It's also worth checking that the carton or bottle isn't swollen, dented or leaking on the shelf; damaged packaging can let in air or bacteria.

What Does the Packaging Tell You?

The fat-content information on yoghurt and dairy packaging (full-fat, low-fat, fat-free) directly affects the texture and taste; full-fat yoghurt is usually thicker and creamier. A label mentioning live probiotic culture is often a sign of a fresher, less processed product, since live culture doesn't survive heavy heat treatment.

Storage temperature information matters too; products whose cold chain has been interrupted can lose their texture, so it's worth making sure the item on the shelf has actually been kept refrigerated.

How Do You Judge Texture and Appearance?

Good yoghurt should look smooth on the surface, without too much liquid separating out when you dip a spoon in; a thin layer of water on top is normal, but nearly half the container filling with liquid can mean the product is old or lower quality. Milk should pour smoothly and evenly when shaken, without lumps or curdling inside the bottle.

Cream and clotted cream should be closer to white than yellow; an overly yellow tint can sometimes mean artificial colouring was used, so it's worth checking that against the ingredient list.

How Do You Test the Smell and Taste?

Once opened, yoghurt and dairy products should smell mildly sour but not unpleasant; a sharp, ammonia-like or musty smell is a sign of spoilage and the product should be returned unopened. An overly sour taste or a grainy, gritty texture in the mouth is another sign of spoilage.

If the colour has turned greyish or you spot even a small patch of mould on the surface, the product should not be eaten at all; that single spot can mean the spoilage has already spread through the whole thing.

Common Mistakes at the Supermarket

One common mistake is picking discounted items close to their expiry date to save money and then leaving the cold chain broken on the way home; even a short spell in a hot car can speed up spoilage. Another mistake is comparing yoghurt brands on price alone without ever reading the ingredient list.

Buying a large tub without planning to finish it before it goes off is also common; once opened, a container can spoil faster than expected, so it's safer to choose a size that matches how quickly you'll actually eat it.
