If you don't activate yeast then there will not any fermentation activity at all. So if there are no fermentation activity then there will not any alcohol content also. If we take one liter bottle, then we can say that one liter bottle contains 3% alcohol content. So if we take 10 liters bottle, then its alcohol content will become 30%. So if there are no fermentation activity means no alcohol content also means no effect on our body as well.
