This I did – except by the third year it was slightly oxidised. I tried every trick – Casein; PVPP; Charcoal. They all lessened the oxidation, but did not remove it.
So, rather than fight the oxidation I decided to embrace it. I spiked the wine to 20%ABV with Everclear and sweetened it up to 8bx with Petite Sirah Concentrate. The result is a slightly tawny Petite Sirah. Quite pleasant.
