Default Carboy calibration

I just found out today that some vendors carry stickers to calibrate the volume in your carboy.

I thought I would pass on how I solved this myself prior to finding this out.

I poured an accurate 1 gallon measurement of water into my carboy and marked the level on the glass with an extra fine sharpy marker. When I had completed the total volume as described above I broke out the Dremel tool and an abrasive bit and permanently marked the lines and corresponding gallons.

I was a little worried about the carboy being brittle so I practiced on some soda bottles first.

That sounds like more work than I want to put into it I only use carboys for secondaries and I'm not too terribly worried about volume at that point. But that's just my system.

A cool trick I came up with (somewhat related) is to fill my BK one gallon at a time and mark it on a yardstick, so I can put the yardstick in my BK and know the volume during the boil.

You can get glass etching kits in craft stores which effectively do the same thing but without compromising the integrity of the carboy.

This is what I did after seeing someone on here do the same. Its just an acid based etcher. I tape off a mark at each half gallon up the entire carboy, then I got a pack of stencils at the same craft store and use those for the gallon marks. Note if you do this, you don't need a big bottle. I thought I'd be going through quite a bit with 4-5 carboys to do, but a little goes a long way, and you can scrape the excess off after etching and reuse it for later, so now I've got a whole bottle laying around and I'm trying to come up with new things to etch. Thinking about maybe doing some bottles

How about some custom pint glasses. Who doesn't want their name all over their beer glass?

Whiteout works really well. I've had a carboy marked with it for over a year now and it's hardly worn off.

Super easy; very cheap; very fast.

I put some tape at appropriate levels.

Duck tape is waterproof. Not pretty, but oh so manly. I would like to get around to doing the etching. But I've got a lot more stuff to worry about first. Like learning how to brew AG correctly.

Ditto, Duck tape is the way to go, doesn't come off...even with washings.
