The Best Hydrometer for Homebrewing
Researched by Johnny Alto · last updated July 28, 2026
Short answer: The best hydrometer for homebrewing is the SOLIGT Triple Scale Hydrometer and Glass Test Jar. It measures all three scales a brewer needs, specific gravity (about 0.990 to 1.170), Brix/Balling, and potential alcohol, and it ships with a matching glass test jar, which matters because you should take readings in a narrow jar rather than floating the hydrometer in the fermenter, so you are not buying a bare hydrometer and then discovering you have nothing to float it in. The main things to weigh are triple-scale, include a test jar, it is glass and fragile, and temperature matters.
SOLIGT Triple Scale Hydrometer and Glass Test Jar
It measures all three scales a brewer needs, specific gravity (about 0.990 to 1.170), Brix/Balling, and potential alcohol, and it ships with a matching glass test jar, which matters because you should take readings in a narrow jar rather than floating the hydrometer in the fermenter, so you are not buying a bare hydrometer and then discovering you have nothing to float it in. It calculates ABV from your original and final gravity and covers beer, wine, mead, cider, and kombucha. The honest limit: like every glass hydrometer it is fragile, the thin stem snaps and the weighted bulb cracks if knocked, a glass jar compounds the breakage risk, and readings need a temperature correction since the scale is calibrated to a set temperature.

This is for the beginner-to-intermediate homebrewer who wants a reliable, cheap gravity tool and keeps breaking or losing the fragile glass one. The candidate Northern Brewer hydrometer is sold mainly direct rather than on Amazon, so here is the equivalent Amazon-stocked kit, a break-resistant option, and what to check.
How do the best options for hydrometer for homebrewing compare?
| Pick | Product | Why it makes the list |
|---|---|---|
| Top pick | SOLIGT Triple Scale Hydrometer and Glass Test Jar | It measures all three scales a brewer needs, specific gravity (about 0.990 to 1.170), Brix/Balling, and potential alcohol, and it ships with a matching glass test jar, which matters because you should take readings in a narrow jar rather than floating the hydrometer in the fermenter, so you are not buying a bare hydrometer and then discovering you have nothing to float it in. |
| Best break-resistant jar | Brewer's Elite Hydrometer & Plastic Test Jar (Deluxe) | A plastic test jar and a hard storage case survive a dropped-in-the-brewhouse life better than glass. The hydrometer stem is still glass, and plastic jars scratch and cloud over time. |
| Best no-spill sampling | Fermtech Wine/Beer Thief + Hydrometer Test Kit | The thief lets you draw a sample and read gravity in the same tube, less mess and lower infection risk than pouring into a jar. It is bulkier, pricier, and the acrylic thief must be sanitized well. |
| Best bare workhorse | FastRack Triple-Scale Hydrometer Kit with Glass Cylinder | Cheap, with the standard 0.990 to 1.170 SG scale, and widely used. The tall glass cylinder is tippy and there is no protective case. |
What should you look for in hydrometer for homebrewing?
A few things separate a good hydrometer for homebrewing from a frustrating one: triple-scale, include a test jar, it is glass and fragile, and temperature matters. Weigh these before you buy.
- Triple-scale: confirm it reads specific gravity (about 0.990 to 1.170), Brix/Balling, and potential alcohol so you can read OG and FG and estimate ABV.
- Include a test jar: glass reads cleaner, plastic survives drops; never float a hydrometer loose in the fermenter.
- It is glass and fragile: buy a spare and store it in the tube or case, since the stem and bulb break easily.
- Temperature matters: readings are temperature-dependent, so note the calibration temp (60 or 68F) and apply a correction, or your ABV math will be off.
Read it in a jar, correct for temperature
Two habits make hydrometer readings actually useful. First, always take the reading in a narrow test jar, not by floating the hydrometer in your fermenter or bucket, because in the jar the instrument floats freely and you can read the scale at the liquid's surface without foam, sediment, or the vessel walls throwing it off. Second, correct for temperature. The scale is calibrated to a specific temperature (usually 60 or 68F), and a sample that is warmer or cooler reads slightly off, which throws your original-minus-final-gravity ABV calculation out. Note your sample temperature, apply the simple correction, and record both your original and final gravity, since ABV comes from the difference between them.
