Hi there, can anyone help please. I am sure that virtually all my elderberries were black when I foraged them and poured 40% vodka over them, one inch above berries. When shaking daily, some of the berries appear to be very dark red? Is it possible for the alcohol to have had any effect on colour? Is it still safe to consume the tincture after six weeks of daily shaking? The berries that are not jet black, maybe 20% are very dark red almost purple. Thanks Emily
