This is a thief you'll actually want in your home! Sampling beer or wine is easy with the 19" Fermtech Wine Thief. Allows you to draw samples and take a hydrometer reading at the same time. Faster than using a regular test jar, it lets you return the wort to the fermenter with less risk of infection, cutting down on losing any of your finished product.

  • Efficiently draws wine and beer samples
  • Also takes hydrometer reading simultaneously
  • Sanitize the unit before use, then take a sample, reading and then return the sample back to the fermenter
Note: This product doesn’t fit into smaller ½ to 1-gallon carboys and also will not fit the Herculometer™ for gravity readings.

Vulneable to chemical induced cracking
The thief works exceptionally well for taking SP readings but i have found that it does not play well with certain sanitizers. I use FiveStar PBW and Starsan for cleaning purposes. 30 days after the first sanitation the Acrylic tube showed signs of crazing (numerous small cracks). Based on material compatibility charts either the Sodium carbonate compounds of PBW or the phosphoric acid in starsan may be causing the problem.

Terrific and Easy to Use
This is simple and does away with many of the hassles of getting a hydrometer reading. FYI: Don't try to get the beer/wine into the wine thief with the hydrometer in it. You won't be able to get enough beer in for a reading.

Great tool
I make alot of wine and use this great little tool for sampling ONLY. I fill a glass tube with it to use the hydrometer. So leaking is not a problem, the tube would also be a little small in diameter to use a hydrometer.

Great for pulling samples/gravity readings
Easy to clean/sanitize, inexpensive, and a great tool to have laying around. Gently place your hydrometer inside the wine thief, dip the wine thief in your fermenter, draw it back out, and you can take the gravity reading right through the wine thief. Then drain your sample into a glass and enjoy. This is also very convenient for carboys/better bottles as they have a very narrow opening.

Must have!
This is a must have for anyone who wants to be sanitary about trying their brew before it has finished fermenting. It's helpful and works great for people making MEAD as well. Buy it and be happy!

Nice piece of equipment
The wine thief was very simple to use. I did not have to worry about pouring a sample out into a cylinder to take my hydrometer reading. I know it will be very useful tool for all my brewing and of course my sampling needs (tasting needs).

Must-have for carboy users
When we upgraded to a carboy for fermenting we also purchased a's a great measuring tool and essential to a carboy system. Works great, easy to clean, and provides a nice sample for testing. Great product.

Does what it needs to
It works fine for what it's intended to do. Dripped a little for me, but not enough to prevent taking a reading from it, so not a big deal

The easiest and best way to SG/OG sample your batches
After one use, you'll wonder why there was ever any other way to take pre & post fermentation gravity readings. Highly recommended.
