More on Diam

If like me you are a bit geeky in your love of wine, you might like to know a bit more about my visit to the producers of Diam technical corks described in Corks fight back published last Saturday (to which I have just added a coda). 

The Diam operation is a subsidiary of the company now known as Oeneo, which is 63% owned by the family who control Rémy Martin cognac. Oeneo’s other subsidiaries are coopers Seguin Moreau, oak-chip specialist Vivelys Boisé and, since 2015, the Portuguese natural cork producer Piedade.
