i used that calc but is it in metric, imperial or glasses
the mini kegs i'm using are only 5L44ml out of 237ml = 18.5% of the total volume. Assuming the 237ml is the total size of the glass in the ratio.
So 18.5% of 9000ml (mini keg) is 1665ml.
So 1.665 litres of rum in a 9 L keg should do it... I think.
edit- oops, you only have 5 litres of ginger beer. So 925 ml of rum in 5l of ginger beer.
It's in volumes. Choose shengs if you want, it don't matter.
You know the alc content of the ginger beer right?
And you know the alc content of rum?
And you know the alc content you desire?
And the amount of ginger beer you have?
So if you have 5l ginger beer from the store with 0 abv = enter 0
and rum from the store with 37% abv = enter 37
And you want it to be 9% abv = enter 9
And you have 5l = enter 5
The calc will tell you that you need 1.607 litres of rum.
You can do it as buckets or barrels or mouthfulls, it still works out the same.
C'mon, seriously; I dropped Maths in Yr10 and even I get this. Are you able to walk and chew at the same time?the mini kegs i'm using are only 5L
