How much alcohol will 100g of pure sugar produce ?

[andy-10]

If I were to put 100g of pure white sugar into 1 lt of water, with some alcohol-resistant yeast (eg Champagne yeast), how many mililitres of pure alcohol would be produced when all of the sugar had been converted ?

Is there a table somewhere which displays this ?

Thanks.

100g in 1 litre will give an OG of about 1.036 so if that ferments to 0.990 with a wine yeast a drop of 46 points = 6.25% alcohol by volume.

There are plenty of hydrometer tables on the interweb if you run a search.


That's 100g in 1 litre, not 100g added to 1 litre, which would give more than 1 litre.

Thanks.

That's what I made it too. After posting I found a recipe for fermented spirit.

It said that 8kg of sugar added to 21 lt of water would produce 25lt of 20% spirit.

So that's 5lt of pure alcohol.

1.6kg of sugar would make 1lt, and so 100g would make 62.5 ml.
