Why do some people put egg shell in coffee grounds?

Adding eggshell to the grounds of coffee is said to take away some of the bitter taste that can be associated with cheap or over extracted coffee. People also use eggshell to settle the grounds of the coffee. I believe this to be a fairly rare practice now.

egg coffee in modern coffee maker?

does any one know if this can be done with a regular coffee maker and papar filer?? I have read about it in a few books that take place in mn where i live and was researching it but I can't find a answer anywhere. If anyone would let me know that would be great.

eggshells for one

I am not sure that my ratios were the same, but I used good coffee, and copper pot on the stove top and tried this method because I broke my french press and I was really happy about it. I have had ulcers in the past and this seemed to really mellow the coffee. I tried to make abt 5 cups of coffee and used a the whole egg and all the shell and though it turned out a bit weak, it was mild and caffinated. And I can see that i will try this again in the future.

Eggshells in coffee

Thanks so much, fellas. I am a thorough Marx brothers addict, and in one of my favorite movies of theirs - "The Big Store" - Harpo adds eggshells to the coffee maker's basket for Groucho's breakfast. This ALWAYS puzzled me, but now I have the answer thanks to my fellow java aficionados.
As a chemist, I agree that the calcium compounds in the shells would likely neutralize a small portion of the acids. Naturally, if you crush the shells more, there's more surface area to react, and slightly more neutralization.
Avoid decaf, unless it's by water process! They extract the caffeine with dichloromethane (or methylene chloride as it's also known) which is a known carcinogen. But then, why drink decaf? Don't we all love our Vitamin C? (C for caffeine... ;-) )

How to produce decaf

Im pretty sure that now a days caffeine is extracted usin super critical carbon dioxide, which obcause leaves no nasty organic solvents in the coffee. But other than that i agree why would anyu one drink decaf

DO EGG SHELLS IN COFFEE REDUCE ACID...?

Is it true that putting egg shells in coffee grounds de-acidifies it? If they produce a smoother cuppa is it because of the neutralizing effect of the egg shells?

I have Interstitial Cystitis and am experimenting with foods that may bother my condition.

Egg Shells Can Reduce Acid

This website has a list of acids found in coffee and relative amounts created during brewing. http://www.coffeeresearch.org/science/sourmain.htm

To answer your question, calcium carbonate from eggs could have the ability to neutralize the acids in coffee. The large particle egg shells don't have alot of surface area. If you grind the shells into a powder, then you have enough surface area to dissolve and react more readily. As an additive to coffee, you would get the neutralization of the acids and still maintain nutritional calcium intake.

Egg shells added to grounds

I recently read a depression era cookbook, how to use eggshells to prepare a smooth cup of coffee. I do remember something of this from my childhood as well. I boiled the eggs peeled them then baked the shells at 350 for about 10 minutes, crushed them and placed them in a zip look bag. I placed about 1 teaspoon full with my grounds this morning. Wow what wonderful smooth tasting coffee. I just love to find and use these old tips. Oh be sure and save these grounds for the spring flowers. God bless and enjoy your cup!

Egg Shells in Coffee

Hi Everyone, I'm new to this site. I tried to make a comment earlier but it appears that I was not successful. I'll try again. I've heard of adding egg shells to coffee to make it smooth. I did not know if it would actually work and was always concerned about trying it. I'm glad to know that it really works. Thank you for confirming this.

egg shells added to grounds

to clarify, you added coffee to the crushed eggshells together and then brewed them in a paper filter?

Thank you

dangerous practice

This would be a very dangerous practise because there are many people who are anaphylactically allergic to eggs (fatally allergic). Please tell your guests if you do this.
