tea and coffee
The local Rooibos tea, made from a herb from the Cederberg Mountains is a favorite for many South Africans.You will find coffee shops in most shopping malls, such as Mugg&Bean (http://www.muggandbean.co.za) and House of Coffees (http://www.houseofcoffees.com/) . Coffee shops similar in concept to Starbucks, like Seattle Coffee Company and Vida e Caffe (http://www.vidaecaffe.co.za) Portuguese themed, are becoming commonplace.
liquors
Amarula Cream (http://www.amarula.co.za/) is made from the marula fruit. The marula fruit is a favorite treat for African elephants, baboons and monkeys and in the liqueur form definitely not something to be passed over by humans. Pour over crushed ice and enjoy. The taste, color and texture is very similar to the world famous Baileys Irish Cream.Cape Velvet is a favorite in and around Cape Town.
wine
South Africa has a well established wine industry with most of the wine produced concentrated in the Cape Winelands in the Western Cape and along the Orange River in the Northern Cape. Wine is plentiful throughout the country and very inexpensive.
beer
Local beer production is dominated by SABMiller (http://www.sabmiller.com) with Castle, Hansa, Black Label and Castle Milk Stout being most popular brands. There are also Micro Breweries all over South Africa. Imported beers such as Stella Artois and Grolsch are also widely available. The Namibian Windhoek brand beers are also popular and generally available.
Prices can vary widely depending on the establishment. Expect to pay anything from R7 to R18 for a beer.
