Coffee and stomach trouble.
Does drinking coffee make your stomach hurt?
Sometimes when I drink coffee I make at home my stomach hurts an hour or so later. Why is that? Is the caffeine causing the trouble?
It is likely that you have a sensitivity to the acid in the coffee.
There are a couple of ways you really can reduce the acidity of your coffee.
Option one involves adding crushed egg shells to the coffee grinds before you brew.
When researching this a couple of years ago I learned that people have been adding egg shells to coffee grinds for a long time now, including in the movie "The Big Store", in which Harpo adds eggshells to the coffee maker's basket when he's making Groucho's breakfast.
It seems that the calcium compounds in the eggs shells help neutralize the acidity in the coffee, resulting in a milder and less acidic brew.
This is probably a great tip for people with sensitive stomachs.
Option two is to use a cold-brew process. The cold-brewing method reduces the amount of acid in any coffee by a huge amount.
This means you can use any coffee beans and still get a low-acid brew.
The brewer you need to use is called the Toddy Cold Brew System. There is no hot water or "brewing" involved. All you use is cold water and ground coffee.
The low-acid coffee it produces is actually a concentrate. You keep this in the fridge, for up to three weeks, and then add some concentrate to a mug and then top it up with water when you're ready for a cup of coffee.
As far as I know, this is the best solution for low-acid coffee. Toddy claims that their method reduces acid in coffee by 67%.
You can learn more and buy your Toddy Cold Brew System from Amazon.
