Fermtech Wine Thief

SKU: 8260

The Fermtech Wine Thief allows you to draw samples and take a hydrometer reading
at the same time.


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.

Great concept. Doesn’t have a way to release the wine back into the container if you can’t touch the edge. Like a large carboy. Needs to have a second release mechanism. Great for taking readings. Much quicker than transferring to a cylinder tube.

Its OK
It would be better if it did not drip so much. Not just stuff running off the sides but the seal is just so so.

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.

a most needed help
this was for sure money well invested. I absolutely love the wine thief, it is perfect to do hydrometer readings and taste tests in a very simple way. It works really well and surpassed my expectations.

Saves me a lot of time and trouble!
This device has really saved me a lot of time and trouble. With it I can not only get more accurate Hydrometer readings, but also see how the wine is clearing at different stages of fermentation.
I would recommend this product!
