This modification was done so that I can easily measure the volume of wort (unfermented beer) or beer in the carboy. Knowing the volume allows for many useful calculations. I poured in water and made 3 measurement lines on each carboy (the glass jug). I used glass etch cream to do the work. All I had to do was put tape around the marks I wanted. Doing the taping was a bit tedious.
Here I am applying the glass etch. These are 6.5 gallon carboys. I also did all my 5 gallon carboys.
These are the lines on a 6.5 gallon carboy. The bottom mark is 5.0, the middle 5.5, and the top 6.0 gallons. The lines are not on top of the glass. The etch is a acid-like substance that eats away a bit of the glass. It does not feel lower, but it is not clear like the rest of the glass.
The finished product. It looks simple, but doing 13 carboys was no small feat. I hope to brew this coming week. I decided I need to dilute the hard water here with distilled water. That should improve the quality of my beers.Happy brewing (or drinking if you don’t brew)!
