Hydrometers & Home Brew Testing Equipment | BrewCo UK

About

A hydrometer is the single most important piece of testing equipment in home brewing — it measures the specific gravity of your wort, beer, wine or cider so you can track fermentation, calculate ABV, and know exactly when it's safe to bottle. At BrewCo UK we stock everything from the classic glass wine & beer hydrometer to trial jars, thermometers, refractometers and smart digital devices including EasyDens by Anton Paar . Every brewing hydrometer here covers the full gravity range for beer and wine, and most are calibrated at 20°C — take an Original Gravity reading before fermentation and a Final Gravity reading at the end, and the difference tells you your alcohol content. Not sure how the maths works? Our ABV calculator guide walks you through it, or use the free tools on our homebrew calculators page, including a hydrometer temperature correction calculator. Whether you need a simple hydrometer for home brew beer kits or precision digital density measurement, you'll find it here — alongside all the brewing equipment to go with it.
