Here's a fine quality, hand-blown glass TRIPLE SCALE 10" hydrometer to measure the specific gravity of your homebrew. If you are going to brew beer or make wine you definitely need one of these so that you can be sure you have your sugar right.
The plastic test jar and other props shown in the photographs are not included. You are buying the hydrometer and plastic tube case with instructions and red cap (see second and fifth image). The scale is about 10" long and 1/2" across the fat end. It is weighted with packed metal filings.
Made in the USA. Hand-blown glass. Hydrometer comes in a plastic case with instructions.
You need to take at least two hydrometer readings: The first is to determine if the percentage of sugars is what it needs to be; and the second is to determine how much sugar was fermented out into alcohol. You just deduct the second reading from the first reading and the difference (lost sugar) will be your percentage of alcohol. It is also a good idea to take readings all along the way to keep an eye on how things are going. This is used for Beer and Wine and will not work with distilled spirits (See our other items!).
This scale will determine the direct percentage of sugar solids in liquids with a specific gravity greater than zero. Before you pitch the yeast, just put a sample of sweetened liquid containing alcohol in a test jar (dollar store bud vase or see my other items) and float the hydrometer in the liquid. The hydrometer is blown glass and fragile so be careful not to let it bounce off the bottom or sides. Spin the hydrometer to release any bubbles that are sticking to it. At eye level read the number off the scale where the hydrometer emerges from the liquid. Be sure to read across the two bottom corners of the frown :( not at the meniscus [top of the curve].
In the third photo you can clearly see the curvation of the meniscus where the liquid clings a bit to the hydrometer and climbs up from the flat level of the liquid. You would take your reading across the level of the liquid, NOT the highest point the liquid reaches, so the reading shown would be 1.06 or maybe 1.058.
