This is a great value Hydrometer test cylinder. This saves kombucha, because less is required to measure than putting it in a bottle as tall as the hydrometer. It helps the hydrometer to have a more accurate reading, too. I only like kombucha to be low alcohol, so this helps with that. There is little problem with having this value cylinder. It is a necessary addition to the hydrometer, and in my opinion is better than a glass one that could easily break.

I’m not sure why I bought this but it just gets me going every time I think about it.

This is a wonderful product for wine/mead/beer making, as it’s large and will last over time.I would absolutely recommend, and purchase this item in the future.I had purchased many glass graduated cylinders for gravity readings while making mead.Typically glass is going to give you a feeling of safety, as it’s easier to sanitize and should be non-porous. Unfortunately, I have literally shattered the bottom off of every cheap glass cylinder while gently sanitizing in a bucket.I realized with gravity readings, you don’t really need a totally sanitized cylinder. You’re not going to reintroduce your sample to the fermentation/secondary - lesson learned, go plastic.I would love to add a photo, but Amazon will not allow camera access without photo library access.

ideal product for testing but the plastic could be a bit clearer than what it is difficult to read the hygrometer..

Graduated Cylinder arrived in good shape. It's a sturdy unit, fairly easy to read. Works well for what I'm using it for which is gravity readings for home brewing and wine making.

As the title states its plastic and foggy wich makes it very difficult to see through wich is very important when using a hydrometer.
