What causes coffee to smell like skunk? It’s not just one thing, but a combination of factors. Here are four reasons why your morning cup might reek of animal urine:

1. Your coffee pot is dirty. Dirty pots produce more toxins, which then end up in your coffee.

2. You’re using old beans. Fresh beans contain oils that mask the smell of urine. Old beans will already be dry and have less oil, so the smell will be more pronounced.
