In Cape Town, South Africa, a popular coffee chain, "African Brew," plans to introduce a new line of artisanal blends sourced from local farmers. They organise a tasting event at their flagship store to generate excitement, inviting local influencers, bloggers, and media outlets to experience the unique flavours firsthand. Concurrently, African Brew launches a social media campaign, #TasteofAfrica, encouraging customers to share their thoughts and photos of the new blends. As part of its commitment to sustainability, African Brew pledges to donate a portion of the proceeds from sales of the new blends to support community farming initiatives in rural areas.
