Inspired by the traditional viticulture that has existed in Bilbao, Spain for thousands of years, this project invites locals and tourists alike to gather and enjoy the traditional Spanish grape juice drink mosto. By creating a new community identity around manufacturing and socially enjoying mosto, the community spirit between locals, tourists and immigrants is revitalised. This in turn becomes a focus of strategic cultural renewal by reclaiming the identity of the island that this project sits on, Zorrotzaurre island, which was originally called Erribera, the waterfront.

The Erribera Grape Juice Production facility aims to give the islanders a new unique identity through the production of mosto. When an area creates a product of high value it in turn marks the location as one of high value causing the produce and location to become inherently interlinked, strengthening the communities on the island.

By giving the islanders an identity, it provides a way of healing the divides in the physical and emotional fabric of the city caused by high levels of emigration and increasing social exclusion at the end of the 20th century due to the industrial crisis.
