In January of this year, Craig Wilkinson, founder of Quantum Culture, a venture creating and trading biodynamically produced and processed goods, visited us here at the winery during the annual Biodynamic Association of Northern California (BDANC) meeting. Craig had been looking forward to conducting an experiment with Biodynamic® dyes for some time, so the weekend BDANC conference at Frey Vineyards was the ideal testing ground. Craig prepared biodynamically grown cotton tee shirts and bandannas in a mordant of alum, and formulated three dye baths: one made from grape lees, another from a filtered grape juice, and one from actual finished wine. Of his experiments, Craig provides the following notes:
- The first dye bath was made from a slightly diluted soupy batch of grape lees, which are the sediment left following the grape crush. The mix was heated for several hours and again the following day. The colors it produced were the lightest of the three baths.
- The second dye bath was made from ‘waste wine,’ which is grape juice collected from the pre- and post-pumping process. The colors were very nice with darker results.
- The third bath was made from nearly a case of 2005 Frey Biodynamic® Syrah made from biodynamically grown grapes. The color was beautiful, and the darkest of the three. The color set very quickly for both the juice and wine, and required no filtering, which made it easier and efficient to work with. Luke Frey and I enjoyed a glass of the Syrah while opening and pouring bottles of wine into the dye vat.
We’re excited about the range of colors, the colorfastness, and the potential for a volume dye bath made from biodynamic winemaking byproducts, and we’re appreciative of Craig’s dedication to the project.
