Hi everyone I've made my first attempt at making beer from water malt hops and champagne yeast it's in a 4 litre container and I added half a bag of sugar I've been trying it every so often and it tastes really nice but not like beer it actually tastes like strong ice tea lemonade kind of taste its been fermenting for 15 days should If I leave it longer will it start to taste like beer or should I cold crash it now ?

What would happen if you added sugar and yeast to vodka to try and ferment it
