Its my first time. I want to make some wine. Please tell me how I increase my wines alcohol percentage around 60%. 

* Is it possible, Does anyone know the process?
* How much yeast, should I use in the grape juice?
* I have baking yeast and I can’t collect Brewer’s yeast, can I convert baking yeast to brewer’s yeast?
* Can I add liquid ginger in grapes juice?
* How do I know if my wine is unfit for drinking?
