Sugar measuring spoon (beer brewing)

These are three measuring spoons for sugar. They can be used for 330ml, 500ml, 750ml bottles of beer.

Attention: The exact weight depends on the sugar you use. I calculated the the volume of the spoons with a density of sugar of 0,67kg/dm^3. It works for casual sugar you use at home and you don't have to always fill it up to the top. (because the density is slightly higher in reality.)

To sum it up: If you fill them completly it's ok, if you fill them only to "90"% it's ok. It always works. Beer is not that sensitive!
