How much dextrose to bulk prime 19 litres (5gal US) of beer.

[Voskar]

It is recommended to use 3/4 of cup to prime 5gal US of beer.
I also read that 8g per litre is also the recommend primimg rate.
8g by 19 litres is 152 grams.

When I weight out 152 grams of dextrose that came to 1.5 cups(UK)?
That's twice the recommend 3/4 cup!

If I use the 8g per litre will I over prime my bottles.
I have check my scales and they are accurate.

Whats going on.

What should I use?

Thanks

Typical amounts of priming sugar for bottled beer range from 4 to 5 ounces of dextrose in 5 gallons. Figure 100 - 135 grams, depending on the amount of carbonation desired.

Forget the measuring cup, the weight of a given volume will vary quite a bit, depending on how fine the sugar is.

Yes the dextrose I have is very fine. Much finer than household sugar.

I always use .75-1 ounce per US gallon. I think that's about 20-25 grams per gallon. So, definitely not as high as the 153 grams you mentioned- more like 100 grams. Weight is far more accurate than cups- I always weigh my sugar and my hops, as well as my grain.

+1000 on weighing rather than scooping.

And I use this to help calculate how much to use.
