Coffee + Coir?

I've been reading different threads extolling the wonders of coco coir with 20% coffee. However, for all my searching, I still haven't found a proper coffee tek.
People will talk about coffee grounds, used coffee, coffee liquid as a hydration tool.. So I need clarification. Simplest possible explanation, how do I go about obtaining the final product I mix in with the substrate? [Assuming I want actual coffee in the mix, not just as hydration].
Do I get instant coffee or the proper un-ground coffee beans a barista would use, and grind it up?
Instant coffee - put two straight teaspoons in the expanded coco coir [while still in water], mix? Or do I put it in hot water, mix, wait for it to cool, then mix with the coco coir?
Ground coffee beans - same story?
People talk about used coffee beans. Are they referring to the gunk left in the strainer in the cappuccino/whatever machine that has had hot water forced through it to make the coffee? Do I get this, dump it in with the coco coir, mix, PC, and use as substrate?

You use "used coffee grounds" you can get them for free from starbucks You just add a little before you pasteurize. I have seen commercial growers only using used grounds but I don't know what types of mushrooms that would work well with They were doing button.

The coffee you use in substrates is ONLY what you empty out of the strainer or filter after brewing a pot. In other words, leached coffee grinds. Do not use instant or liquid coffee in substrates. Mix coffee in any percentage you want. I've grown on pure coffee. The more items you mix into the substrate, the better. If you have manure, coir, worm castings, compost, coffee grinds, straw, etc., use a little of all of them. Add up to ten percent by volume of gypsum and mix all the dry ingredients. Then, add water to field capacity and pasteurize. RR

Ahh, excellent. I get you. We have a coffee machine at home so I can use that easily, it'll amount to a couple teaspoons.
I also bought two bricks of coco coir and a 5L bag of spaghnum moss. I think this next grow is going to go very nicely

Yes, when using any bulk substrate you need to pasteurize to get rid of the bad bacteria leaving behind the beneficial ones.

Somewhat true, but you're more concerned with killing molds than bacteria. If it's hydrated properly (not over-wet) bacterial contamination is rare. Molds, however, will wreck your grow as they propagate much faster than mushroom mycelium and grow in similar (if not identical) environments. Mycelium is also better equipped to fight off and overtake bacterial contamination than mold conatmination.
But yes, you do need to pasteurize any bulk substrate.

I just used a full brick of coir (8 liters expanded) and 1 litre of espresso/coffee grounds ( mostly espresso, only stuff they had at the bucks), and combined about 2.5 cups of ground oyster shell (pretty ground up, like fresh ground pepper). I pasteurized for about an hour and 45 by accident.
My question is, i'm noticing an awful lot of oils on my tools and containers, will this be ok?
Why add gypsum? Is it to balance out the acidity of the coffee? How much of a difference will it make?
Thank you for your help.
