Is Coffee Acidic?

Yes, coffee is naturally acidic, typically ranking around a 5 on the pH scale. This acidity comes from organic compounds like chlorogenic and citric acids released during brewing. Traditional Singapore kopi beans are roasted with sugar and butter, which can alter the flavor profile but still retains a level of acidity that may cause discomfort for individuals with sensitive stomachs or acid reflux.
