Certain fungus prefer certain food.
Some are pickier than others.
Luckily, winecaps are pretty hungry.
I have not had luck with a primarily pine/cedar/conifer chip with winecaps but something that it will devour is a mixture of
cardboard and fallen deciduous leaves. You can even utilize hay but be warned that it will be gobbled up quick.
I have found, oddly
enough, box elder wood is a favorite of many mushrooms. I do not know what it is but I have had winecaps, elm oyster, golden oyster, and a few other inoculate onto box elder without much issue.
