Review on Deluxe Wine and Beer Testing Kit: Ubrewusa's All-in-One Fermtech Hydrometer and Test Jar with Thief by Joel Young

Overall a great purchase, the hydrometer was clearly marked and easy to read and the Weinthief seems to be doing its job well. The only issue I had was that the wine thief didn't fit in my 1 gallon bottles (I put a #6 cork on them if that helps you figure out the hole size), which was really unfortunate. But I bought it primarily for a hydrometer, and since the cost of this product was in the range of what I would pay for *each* of the items included, I think I might be missing a wine thief. doesn't fit in my 1 gallon bottles. However, if you think of it primarily as a wine thief, make sure it fits your bottles before you buy it.
