The VEVOR 13.2Gal Alcohol Still is mostly made from food-grade stainless steel, according to how the manufacturer describes it. This material is tough, doesn't corrode easily, and is simple to clean, which is really handy if you're using it a lot for distilling alcohol or other stuff.

On top of that, the still includes a copper coil. Copper is great because it's awesome at conducting heat, which is super important for the distillation process. It also helps get rid of sulfur compounds, which can mess with the smell and taste of your final product.

Our research shows that people generally like how solidly this still is built. The quality of the copper coil often gets a shout-out since it helps improve the overall results of their distilling.

Just remember, it's key to keep both the stainless steel and copper parts clean. This makes sure everything works well and stays in good shape over time.

From what we've found, the cooling system on the VEVOR 13.2 Gal Alcohol Still seems to do a good job overall. A lot of folks appreciate that it comes with a built-in thermometer, which gives you readings in both Celsius and Fahrenheit. This feature really helps keep track of the temperatures, which is key when you're distilling things like spirits or essential oils.

Our research indicates that the thermometer is generally well-regarded for its accuracy. Most people have had good experiences with it, though there are a few mentions of it fogging up or acting up, but these seem pretty rare overall. One person even pointed out they didn't face any issues even after using it for a long time.

One thing that comes up is the importance of setting up the still correctly, especially to get the best cooling and temperature control. The position really matters to make sure you get the most out of the thermometer's precision. Once it's set up right, many people say it's a big help for getting the distillation temperatures just right.

There are some notes about the setup process being a bit tricky, especially with the instructions. So it might take a little patience to get everything going.

But once it's up and running, folks generally find it performs well, whether you're new to distilling or have been doing it for a while.

In the end, it seems like the cooling system and thermometer together make this still a solid option if you're looking to distill with some precision. Just be prepared to spend a bit of time on the initial setup to make sure everything works smoothly.

The VEVOR 13.2 Gallon Alcohol Still can hold up to 13.2 gallons or 50 liters, so it's great if you're planning to distill larger quantities. According to the manufacturer's description, it's designed to handle a variety of tasks, whether you're distilling alcohol, water, or even essential oils.

Now, if you're thinking about using it for essential oils, it's worth noting a couple of things from our research. Some folks pointed out that the thumper keg, which comes with this setup, might be a bit small for getting the best oil separation. If that's your main goal, you might want to look into getting a bigger thumper or making some modifications.

There's also the instruction manual to consider. According to our research, it's a bit skimpy for beginners, so many suggest looking up some online videos and tutorials to get the hang of setting it up and using it effectively.

Overall, the VEVOR still can be pretty versatile, but if you're aiming for specific results—like perfecting essential oil distillation—you might need to do a bit of tweaking or extra homework on the side.
