Measurements for priming bottles

Hi All!

Firstly, thanks again for all the fantastic info that comes out of this forum... I reckon my knowledge of homebrewing (while still tiny) is growing dramatically because of it....

I'm putting down a brew this weekend, but will use the Coopers Carbonation drops as thats all I have at the moment...

For my next brew I'll use dextrose, as it seems to be the recommended primer.....

However, I'm just a bit confused as to how much dex you add to bottles for priming... People say 'a full measure' but what is a measure?
For example, if I was to prime a 750ml bottle how much dex should I use? or a 330ml, or a 500ml?

Thanks again chaps for all your wisdom!

Cheers,
Saul

work on 8 grams per litre

so...
750ml = 6 grams
500ml = 4 grams
330ml = 2.64grams

cheers

You can also bulk prime or just grab a priming scoop from your Hbs they have all the measurements that you just mentioned

If your going to bottle into different size bottles I would recommend you look into bulk priming. Do a search there's heaps of info in the forum on different ways to do it.
I generally only bottle into long necks (750ml) these days, but always use bulk priming as it's so easy and simple. Check out this link for details as to how much dextrose to use for different brews/carb levels.

Thanks for all the advice chaps...

One question - does anyone know roughly how many grams a teaspoon is - about 6?
Thus, a 1/2 teaspoon would be 3?

I'm putting down a nice Irish Stout next, and don't think I need a lot of carbonation...
I'm going to be using 22oz bottles (here in the States) which is about 650ml.....

thanks again for the advice....

1 teaspoon = about 5 millilitre ( ml ) = 5 grams ( g )

The Australian standard is 1tsp = 5ml.

For water at 20C that is exactly 5g (by definition).

For sugar it's less (think of all the air gaps between the grains!)

I just did a little experiment: I got our electronic kitchen scales which are
accurate to 1g and measured the weight of 10tsp of castor sugar and 10tsp of normal white sugar. In both cases the 10tsp quantity weighs 45g, so 1tsp weighs 4.5g.

YMMV.
