Measuring Alcohol Content in IPA Beer Batches<\/b><\/p>\n

Indiya from Home Microbrew would like to measure the alcohol content in her IPA beer batches to assure consistency. She is not sure what methods are typically used to get the specific gravity reading, as she saw many calculators and conversion tables online.<\/p>\n

What would you suggest for her small home-based company?<\/p>\n

    \n
  1. A 0 to 20% alcohol content hydrometer such as the H-B Instrument Alcohol Proof Ethyl Alcohol Hydrometer<\/a> <\/b><\/li>\n
  2. A 0 to 200% alcohol content hydrometer such as the H-B Instrument Alcohol Hydrometer, 0 to 100% Tralle, 0 to 200 Proof, Combined Form<\/a><\/li>\n
  3. A specific gravity hydrometer such as the H-B Instrument Hydrometer, 1.000 to 2.000 Specific Gravity, 0.01 Divisions, Plain Form<\/a><\/li>\n
  4. A hydrometer jar such as the Thermo Scientific\u2122<\/sup> Nalgene\u2122<\/sup> Hydrometer Jar<\/a><\/li>\n<\/ol>\n

    Answers:<\/b><\/p>\n

    1. A 0 to 20% alcohol content hydrometer such as the H-B Instrument Alcohol Proof Ethyl Alcohol Hydrometer <\/b>(08296-01)<\/p>\n

    \u00a0Correct!<\/b> \u00a0IPA beers typically have an alcohol content between 4 to 8%. Though the content may be slightly higher for home brewers, it still falls within the range of the hydrometer. These hydrometers are very easy to use and this model will keep her from having to convert the specific gravity readings to alcohol content through a table.<\/p>\n

    2. A 0 to 200% alcohol content hydrometer such as the H-B Instrument Alcohol Hydrometer, 0 to 100% Tralle, 0 to 200 Proof, Combined Form (08285-58)<\/p>\n

    \u00a0Although this hydrometer would work, IPAs usually have alcohol content below 10%, so this range would not allow great resolution\u2014and therefore accuracy\u2014for Indiya\u2019s needs.<\/p>\n

    \u00a03. A specific gravity hydrometer such as the H-B Instrument Hydrometer, 1.000 to 2.000 Specific Gravity, 0.01 Divisions, Plain Form (08298-94)\u00a0<\/p>\n

    Incorrect. Using this method, Indiya would have to convert the specific gravity readings to alcohol content by using a conversion table. There are more direct ways for her to determine the alcohol content.<\/p>\n

    \u00a04. A hydrometer jar such as the Thermo Scientific Nalgene Hydrometer Jar (06135-65)<\/p>\n

    \u00a0Incorrect. A hydrometer jar does not provide any readings; it is made to hold hydrometers.\u00a0 A graduated cylinder may also be used or any other type of clear jar so the meniscus of the liquid level can be read against the scale of the hydrometer.<\/p>\n","protected":false},"excerpt":{"rendered":"
