Kumala — a winery in South Africa — is offering free wine charms to those who successfully complete the Kumala Safari Challenge, which is an 8-question quiz pertaining to facts about South Africa. Offer is valid only in the USA, and the questions are pretty easy.
I’ve never had anything from Kumala so can’t comment on the quality of the wine. But the charms might be nice, especially for your next wine party — this way you’ll know which glass is yours once it leaves your hand.
