Metal rod for measuring volume
« on: April 08, 2012, 06:01:03 AM »
Question for the forum:

I am a relatively new all grain brewer and to this point I have been "eyeballing" volumes in my keggle.  Naturally, this has given me mixed result so I want to create i measuring stick taht I can notch/mark at different volumes.  I found a metal rod in my basement that would be perfect for this if I cleaned it up.  It appears to be some sort of generic steel. 

The question is if this metal would have any noticable effect on the beer.  I know its probably not the ideal material, but since it would not contact the wort for very long, would I be OK? 

Thanks
Snotter

Mild steel might give you some iron in the beer, not so good, but short contact times might work if it is clean and rust free.  Other might know more. 

I have a long wooden dowel notched at 1 gallon increments.

A plastic rod would probably be better. Maybe hit up your Goodwill and find a cheap cooking utensil to use?

i would not leave it in but dipping it in and out would not likely cause any issue.

I have a 36" stainless steel rule that I bought from a tool store. It works great but I now use Blichmann kettles with calibrated sight glasses. A wooden dowel or yardstick would also work.

I used an old wooden spoon with notches cut into it and defined with a Sharpie. I made marks on the inside of my kettle starting at 5 gallons. That's what I use now.

I notched my mash paddle. Multi-tasker.

My only concern would be if it is galvanized steel.  Potential issues with leeching zinc and producing off-flavors.  Not sure how much contact time it would take, but since metal unknown, I would not put in my brewing.

I use a copper pipe, marked off in 1 gal increments using small hacksaw cuts. I've also use a notched plastic stirring paddle.

The key would be to "notch" the plastic or metal rod/tube with, say, a turn of the pipe cutter or kitchen knife.  Numbering the notches is more difficult--a dremmel might be the best tool.  From personal experience, I can say that a black sharpie does NOT work.  The wort pretty much dissolves it right off of a plastic mash spoon.  All the time spent adding a gallon at a time to the BK was wasted.  Plus, black sharpie stuff got dissolved into the wort--not necessarily what one wants in the beer.

Yeast need trace amounts of copper and zinc.  Wort is zinc poor.  There are stories of German brewers that have all SS breweries that will leave a zinc coated ladder in the kettle and pull it out later, or that have a section of galvanized pipe in the otherwise all SS piped brewery.  Up to 0.2 ppm zinc is a good thing for yeast health.

Hypothetically (of course) one could use any US penny since 1983. 
You'll get both copper and zinc.

I use a typical brewing plastic spoon and marked water levels with a sharpie!

How did you mark it? Mine is imprinted every 2 gallons and I want it to show quarter gallon increments. Dremel?
