A White,
Actually you want to eat the mushrooms as soon as possible, preferably the same day they emerge.
A young wine cap is a tender, delicious mushroom. Unfortunately the larger they get, the closer they taste to a cross between cardboard and shoe leather. Truthfully, they may already be past their prime. That’s too bad for these mushrooms, but the future mushrooms can get harvested and rated immediately. I have tasted large mushrooms, but they tasted like wood.
The last note I would make is that the more burgundy they appear, the better they taste. If the climate is having an adverse affect on the mushrooms, could you move the container into a cooler place like a basement? When you get done with all the woodchips in your container, place them in the garden and they make wonderful garden
compost.
Hope this helps,
Eric
