The Fermtech Wine Thief is a brilliant piece of equipment for both homebrewing and wine making. The simple design allows the user to extract samples from both beer and wine in a flash. Simply insert the Thief through the top of the neck of your fermenter or bucket and allow it to fill, pull it out and put a standard hydrometer directly into the Thief and take a reading. Just touch the tip to the rim to empty. Made of high grade acrylic for excellent clarity. 19” in length.
