Decaffeinated coffee as mycelium

I’m soaking some rye grain I bought decaffeinated instant coffee by accident (I mean weird right; coffee with out caffeine, it’s like drinking water, that lacks hydrogen).
Probably a dumbass question...
Does mycelium have similar views on decaff or can that be used instead on normal instant coffee?

mycelium is mostly interested in nitrogen. it doesn't need caffeine to wake up in the morning.
Considering there's a lot of nitrogen in caffeine, it can make a difference but I'm not sure.
you'll just have to try it out, I guess. that being said, soaking in coffee is not necessary at all. your grains contain enough nitrogen as is.

I always thought the reason to use spent grounds was because the caffeine is already leeched out.

Not correct, at least in the quantities we use by adding coffee. When I first discovered the benefits of coffee in mushroom growing, I and many others experimented with pure caffeine to see if that was the agent responsible for the increased performance, but it had zero effect.
There's well over 200 compounds in coffee and nobody knows which provide the benefit or if it's a combination of many of them. I've never seen one single mutant come as a result of using coffee in substrates or grains.
Be very careful looking at research papers from the 1960s and earlier when we were just learning how to grow mushrooms in sterile technique. There were so many variables being learned at once, the experiments were often compromised by inexperience. RR
old thread though, maybe outdated... I have little to no experience with coffee, so I'm going to withhold.

I thought it was because it was pasteurised while brewed??

the grains are sterilized afterwards anyway, so I don't think that would matter.
