How much alcohol does your brew contain? The only thing that can provide a quick, clear and conclusive answer to this is an accurate alcohol meter. Most alcohol meters come in handy when making spirits, such as liqueurs. A wine weigher (with a thermometer, such as the one from Vinoferm) can be useful for making wine. Make sure you measure the alcohol percentage before adding sugar, as it is impossible to determine the correct alcohol percentage afterwards. Good to know if you will soon be using that limoncello (or was it arancello?).
