I just learned there was a way to save those white tops and that was to simply keep on with the red wine.
In the dye-pot.
Red wine dyeing is only one of many techniques in Dyes from Kitchen Produce by Setsuko Ishii. This is not an ordinary book. Not only does she set forth a clear guide to dyeing with kitchen ingredients, she includes individual dye instructions for her sewing, weaving, knitting, and crocheting projects as well as patterns & instructions. The design of this book is well-organized, you always know exactly what page to go to for what and how. It is one of those books you have to read in small doses with two squares of 73% chocolate and a cup of mint tea. It's that wonderful. Take a look, you'll see. Ms. Ishii has also authored two other dye books in Japanese, just FYI.
It was one suggested "just for me" in an Amazon email based on previous book orders. Well, I fell for it and Mr. Amazon, as Nat says, did right by me. So right.
I just happen to have some pinot noir that was very inexpensive (and after tasting it, I know why). And I just happen to have some white silk shantung and some white wool and some white floss. And I wear glasses.
It's meant to be.
