Adding water/Learning to count

[Metaphore]

I got 92% from my still and decided that the proportion of this 92% stuff needs to be 44% of the total for me to get 40% ABV vodka. So, I added 700 ml of 92% product to 900 ml of water and it now measures 60% on the alcohometer.

I couldn't make a mistake with the volumes - 2 x 250 ml beakers to the 250 line and 1 x 250 ml beaker filled to 200 ml and it was in 3 separate beakers. This was all of the product from the run. The water was measured with a 1 liter beaker with 20 ml gradations filled to 900 ml. The result is in a 2 liter container and looks pretty damn close to 1.6 liters.

Am I not counting this right? Is it not 700 ml of 92% to 900 ml water?

Thanks

700ml of 92% ABV added to 910ml of water would give you 40% ABV. Bid you add the water to the alcohol. Then test right afterwards? You should add the alcohol to the water. And wait a bit to test. The liquid will heat up when the two are mixed. It's a chemically reaction. So the heat generated will throw your readings off. Alcohol meters are usually calibrated at 60 deg f.

Or you got your measurements wrong?

It was just water right? Nothing added to it?
