Most South African homes don't have a dedicated wine cellar. And unless you're collecting expensive bottles, buying a wine fridge probably isn't high on your list of priorities.

Some white wines are made from a single grape variety. Others bring two or more together, using the characteristics of each to create something different.

You can buy a bottle of South African wine for R80. You can also spend R200, R500 or considerably more. But what changes inside the bottle as the price goes up?
