1. You may add extra ginger if you prefer a stronger wine. However, ginger wine can get really spicy so I have added only 40 gms which when combined with the sugar gives out a lovely sweet taste with a hint of spiciness & alcohol.
2. I added an extra 50gm of sugar (total of 750gm), however I think 700gm is perfect as it gives out a delicately sweet wine.
3. All equipment used should be sterile ie washed clean and completely dry with no traces of moisture. You may dry the ceramic jar/bottle & the wine bottle in the sun (preferably) or just dry it out in the shade for a longer time.
