If your coffee rapidly becomes moldy, you are doing one of two wrong things.
You are buying pre-ground coffee (a big mistake, as it is hydrophilic).
You are NOT storing your coffee in a relatively air-tight canister.
Purchase a small grinder and buy whole-bean coffee—preferably a light or medium roast. Buy a French press or Chemex flask, and then learn the joy of caffeine.
Allow me to risk everything and bet that you live somewhere which has a humid climate.
Its because coffee is part of a plant. The coffee bean, or ground up coffee nbean needs to be kept away from any damp conditions, eben a little steam in the air can cause this, and should be kept in a dry jar with a tight fitting lid, to preserve the fresh coffee taste and aroma, and avoid any dampness or moisture in which mould can penetrate.
If mold were to grow on the coffee the mold could produce mycotoxins which are poisonous and could make you sick if a lot of it is consumed. coffee makers are a moist environment where bacteria and mold can get a start and reproduce in high numbers. The first evidence will be a bitter taste to your coffee. So if that is the case give your coffee maker a good cleaning and drying out. Used Coffee grounds will not get mold if they are dry , so set them in the sun or in a low temp oven if you wish to save them for other uses. If not throw them away after brewing .
coffee is slightly acidic with a ph of 5.2 to 6.9 the average of a cup of yesterday’s brew. mold likes a PH in line between 6.1 and 7.0. So it’s best to make your coffee fresh and drink it fresh , discard yesterday’s brew.
The proper way to store coffee beans is in a dark canister -air tight -in a dark cool temperature environment. I never freeze or refrigerate beans or ground coffee because coffee will pick up moisture and smells changing the coffees taste. guard against sunlight and heat .even a cabinet near your stove or getting direct sunlight is bad for your coffee.. divide your coffee into small packages. coffee begins to lose freshness almost immediately after its roasted. Use one package at a time until it is used up . This will keep the other packages from being exposed to air repeatedly . pre grind only the beans you will be immediately using. And secure your small packages in tight wraps and secondary tight fitting containers these should help preserve your coffee longer. And keep it fresher and better tasting.
I used to live in a hotel and collect all their used coffee grounds in a bin. They were soaking wet when I got them. Drying it out completely was impossible in the hotel (I gave up after destroying two microwaves). Drying them out in the sunlight was just as hard. When I though they were dry, I’d put them into a dry bin and cover them. Then an hour later if I opened the bin, they were still moist. Coffee grounds simply absorb moisture from the air.
