High-quality vinegar varieties need classy packaging that is also easy-to-use, refillable, watertight and leak-proof. For our customer UNILEVER-MAILLE, we carried out a comprehensive market study in line with these demands for product safety and convenience in order to find out which clay and earthenware vessel and which closure is ideal for a select Maille vinegar variety. On the basis of a simple rating system, the customer was easily able to recognise which bottles and corks best matched the parameters of their briefing in terms of shape, material, functionality and price. Following our recommendations, a sleek and elegant black ceramic bottle with a high-quality wooden cork was finally selected.
