If You Want A Better Tasting Home Coffee, Clean Your Coffee Maker
By Lauren Wood
According to a 2015 study by Caffe Nu, 67 bacterial variants, including mold, were found within nine tested coffee makers. Not only can these contaminants make us sick, but mineral and dirt buildup can also obstruct your coffee maker’s natural flow, causing it to brew inefficiently with a less-than-desirable taste; fortunately, there’s an easy way to combat this problem.
To clean your coffee-maker, fill the reservoir with water and vinegar (or just vinegar if it's more dirty), then hit brew to allow the mixture to disinfect the machine and remove mineral deposits. After a brief resting period, take the machine apart to wash the attachments before putting it back together and running it a few times with fresh water to remove any residual vinegar.
For a deeper clean, fill the reservoir with warm water and around 1/4 cup of baking soda before brewing, and then filter fresh water twice more. Running one cup of pure lemon juice through your machine is another great way to freshen your coffee maker, but if your machine has begun leaking or your coffee tastes burnt, it may be time for a new one.
