New bottle holders for prestigious wines

I'm studying a new set of bottle holders.

Seven unique items that rotate around a single topic, the Moon and its movements thought and created to accompany important and prestigious wines. They are all made out of Impruneta cotto, old barrique staves, and piano chords in copper. The idea came about after I took a biodynamics wine making course recently and during which I learned how the Moon, Mercury and Saturn influence the life of the grapevine and its produce.
