Zanzibar is experiencing a surge in the price of beer and other alcoholic beverages due to a limited supply, following the Zanzibar Liquor Control Board's refusal to renew alcohol import licenses. This situation could potentially impact the island's tourism industry, which contributes to 30% of its GDP. The Zanzibar Revenue Authority, which is closely monitoring the situation, is estimated to have already lost nearly $10 million in the past 45 days. The scarcity could also affect the quarterly tax returns of bar owners.
