I tried a little sample taste and its not sweet enough for me. so how do i back sweeten do i just add sugar or what. note ; this kit didnt come with an f packet
You could make up a simple syrup (2 parts sugar/one part water) on the stove and then add it to your wine once it cools. Just add enough until it's almost to where you like it.
Do as Dan says and make sure you have stabilized the wine with k-meta and k-sorbate before adding the simple syrup. As Dan cautions, add it slowly to just below where you think you like it. It tends to sweeten slightly afterward.
