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.

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.

Thank you

Thank you

10 cups water
1/2 cup This is Most Certainly Brew Coffee grounds

Remove from heat and add 1 cup of cold water. (This will settle the coffee grounds to the bottom of the kettle) Serve hot.

Swedish Egg Coffee Howard Ball, ChurchLIFE,

water 10-12 cup
regular-grind coffee 1 cup
egg 1
ice cold water 1 cup

Bring water to a boil and remove from heat. In a small bowl, mix coffee and egg. Add a little hot water to coffee and egg mixture, then pour mixture into hot water. Stir and heat until it comes to a rolling boil. Remove from heat and pour in 1 cup of ice cold water. Let set for 10 minutes before serving. (The egg and grounds settle to the bottom, leaving the coffee a dark honey color.)

RECIPE BY: San Marcos Sunshine
I'm a former Minnesota kid who grew up surrounded by "Lutheran Women Who Cook" (in the church basement) for showers, weddings and funerals. There's even a cookbook available with a similar title. This is the way I recall the ladies making coffee in huge enamel pots, and it's the clearest, most flavorful coffee you'll ever enjoy. I outgrew their 10,000 Jello and Miracle Whip recipes a long time ago, but I fondly remember the Lutheran Church Basement (aka Swedish) Egg Coffee.

Ingredients
1 egg
1 cup cold water, divided
1 cup regular grind coffee
6 cups boiling water
Directions
1Use a graniteware (enamel) coffee pot.
2Wash egg; break it into a small bowl, reserving shell, and beat slightly. Add 1/2 cup cold water, the 1 cup ground coffee and the reserved egg shell, crushed. Mix thoroughly. Turn into coffee pot; pour on boiling water, and stir. (I remember the ladies adding the coffee/egg mixture directly to the boiling water.) Optional: The spout of the pot can be stuffed with soft paper towel to prevent escape of the fragrant aroma. Place on front of range and boil 3 minutes. If not boiled, coffee is cloudy. If boiled too long, too much tannic acid is developed. Add remaining 1/2 cup cold water; which perfects clearing. Cold water, which is heavier than hot, sinks to the bottom and carries the grounds with it. After coffee has settled, serve at once.

Egg coffee

I just read about egg coffee today.

I understand the way to make it. What I dont understand is why one would do this. I know that whipped egg whites are used to clarify wine but dont see that as useful for coffee. Does it impart any taste?

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.
