Suggested Retail:$43. Speakeasy Distillers - Glass Proofing Parrot with Alcohol Hydrometer Tester 0-200 Proof & Tralle, Alcoholmeter Made in Scotland, Home Brewing DIY Moonshine Still Kit Accessories. Parrot allows the distiller to read proof of the run in real time. It is connected between condenser and collection container, allowing the distillate to flow through. The aim is to test the alcohol percentage of the distillate continuously, and let that be the guide to decide where to make the cuts. Fun fact: borosilicate glass is so resistant to chemicals, that it is even used to store nuclear waste. The boron in the glass makes it less soluble, preventing any unwanted materials from leaching into the glass, or the other way around.. 7 DAY FULL REFUND GUARANTEE ON THIS ITEM IF ANY ISSUE IS FOUND THAT WAS NOT DESCRIBED/PICTURED. 7 DAY STORAGE IS ALSO AVAILABLE.
