i love flavored coffees but they might contain a little sugar so...
we use the melita type brewing system where you pour hot water over the grounds into individual cups
to those grounds we add:
several shakes of cinnamon (it's a great anti-inflammatory)
a shake of ginger
a shake of allspice
a shake of nutmeg
a shake of clove
a teaspoon of cocoa
it takes my water a little longer to filter through due to the extra powders
wow best coffee ever and certainly sugar free
i have adjusted to using stevia as a sweetener and it's a great way to start the day, warm & spicey chocolate brew--nice
will add a picture shortly
