how much priming sugar?

[Just-Brew-it]

hi just brewed a stout and i'm ready to keg it, it's a 40 pints edmes stout kit. how much priming sugar? i also have a little bit of pray malt which i'm going to add with the sugar and i'm guessing spray malt has the same sugaryness to weight ratio as sugar?

80g is the usual, I think

I made a spreadsheet to calculaute this as it changes all the time. If you message me your email I will send it to you.

BUT here is the way you work it out

1/2 tsp sugar per 500ml is a good amount to add

Sugar (tsp) = Volume (Litres) x 0.5

so 40 Litres = 20 tsp


1 tsp sugar = 4.2g

sugar (g) = tsp x 4.3

so 20 tsp = 84g


now if we want to use DME, its the same WEIGHT as sugar, but because it has a different dencity, a different number of teaspoons. Not sure on the conversion factor, but again 84g will be good.

To use LME (easy to get a small pot from health food shops, but DO NOT get cod liver oil flavoured) you want to use more than DME. Simple calculation:

1 tsp sugar = 1.5 tsp LME

You dont do a weight conversion again beecause of difference in dencity between the two.

20 tsp sugar = 30 tsp LME


i find it easier to dole out LME in tsp rather than by volume, but for the hell of it:

1 tsp = 4.9 ml

30 x 4.9 = 147 ml


As I said earlier things change all the time. Sometimes I brew 10l, sometimes 15, sometimes 23, 25 etc... Also it depends what I want to use for priming.

Just do the maths and go away, or use a spreadsheet.
