Most everything you need to know about Used Coffee Grounds

Not a chemistry major here, but I recall hearing the hot water extracts more tanins (and perhaps phenols?). Do the grounds produced by these two methods vary in how they work for composting or top dressing?

Cold brewing leaves more tannic acid as well as other compounds that are removed in hot brewing. Spent coffee grounds from either brewing method can be used for; soil additions, composting, worm bedding, etc.

What is SCG???

Wow thanks for all the info! I have lots of coffee grounds. I throw them on my compost pile or just outside around plants, but I’m not very intentional with how I use them. My doctor told me they worked to keep slugs away from her lettuce plants.
