Disappointment at Benguela Cove Lagoon Wine Estate

Visited Benguela Cove Lagoon Wine Estate, recent winner of the Cellar Door Experience of the Year award, with high expectations. Ordered two (different) glasses of MCC. To our dismay both glasses were flat. We complained and were given two fresh glasses. It was also flat! Their reply when we enquired ..... it was flat because they served it in the wrong type of glass!? Why was it served in those glasses? Who knows? It was clear they did not care. We left without the purchases we intended to make. Best cellar door experience .... we vote not so!
