(TheLeader) - There is hardly a sector of industry or commerce that is still maintaining the levels of sales that the recent, more fruitful times brought, but diversity and growth are the only ways to survive it would seem, at least that is what the wine industry are currently thinking. Sales in wine from Spain have been dropping for the last 25 years, according to the director general of the Observatorio Español del Mercado del Vino (OeMv), Rafael del Rey, who is convinced that it will take another generation for the market to recover fully.
