Nigredo Julep Strainer Drawing inspiration from alchemy, the Nigredo Julep Strainer was born. The alchemical path comprises four stages, the first being with the Nigredo, the calcination or death of the raw material. Represented by death and the black raven (as the material had to be calcined until it turned that color), these symbols have been used to create this limited-edition julep strainer. The strainer is hand-forged from 2mm brass, then sanded and polished. Only one unit of the Nigredo Julep Strainer has been manufactured. No further units will be produced after its sale. This strainer ships with a certificate of authenticity, which describes the manufacturing date, the craftsman's name, and the serial number. Remember that any Boleq product includes worldwide free shipping. You can get more information here.
