What were your ingredients and steps? What is the alcohol reading? These are the things that would prevent fermentation.
When you say like syrup, do you mean body or sweetness?
Grapes,blackberries and.mulberries. Added half the sugar and all the yeast. Fermented for about 3 weeks then added the other half of the sugar. Put it on airlock. It's tasted just like syrup, thick and sugary.
