In my brewing practice I always try to use an aphrometer when I bottle.
An aphrometer is a tap with a pressure gauge on it, which shows the internal pressure of the beer.
This instrument is useful for:
- checking that carbonation has actually started;
- seeing that carbonation has ended and the internal pressure is stabilized;
- seeing that something very wrong happened during bottling and there might be excess carbonation in some bottles;
It takes some guessing game out of the homebrewing experience which is a nice thing.
The cheapest versions can be found for €35-40, which is not a huge sum. Some more expensive versions go up to €200 and much more. I bought one of the cheapest kind, which costs around €40.
Although the measure on the gauge is probably wrong in excess, it certainly shows the inner advancing of the carbonation.
I made two attempts at making my own aphrometers, without much success.
I used plastic sparkling wine caps in which I drilled a hole where I screwed the pressure gauge, trying after that to seal it well. The sealing part is the problem. There is no "handle" on the cap and in order to put or extract the cap one applies some tortion to the pressure gauge, stressing the seal.
I read this interesting text, where a suggestion is given to make an aphrometer using a hiking flask. The problem with this is that I was not able to find the right "threader" not even at a large hardware store.

I would like to know whether anybody built a DIY aphrometer and how.
