The Swartland Street Party is Back — and You’re Invited! Prime those palates — the wine producers of the Swartland are getting ready to pour, swirl, and sip their way through another legendary Street Party in the heart of Riebeek Kasteel! Why come? Because some of South Africa’s most exciting wine producers will be there, many pouring rare gems you’ll struggle to find anywhere else in the country. This is serious wine fun in a not-so-serious setting.
