    This is getting pooh-poohed in /r/homebrewing, and I have to agree. There already exist handheld electronic refractometers for this purpose, and they’re about a quarter the price.

  2. mzed says:

    Indeed… the price!  I could break 50 analog hydrometers for that.

    Ah, just stick your hydrometer right in the fermenter – can’t get much faster than that.  You only need two really accurate readings – at the beginning and end of brewing.

      Eh, I’ve been brewing for 20 years and I’ve never even bothered.
      Having a glass of my latest stout right now, based on SN recipe, with my own twist.

      • huskerdont says:

        Wow, that’s pretty laid back. I have no need for a refractometer, considering I’m not making up my own recipes but at most altering existing ones, but I can’t imagine not being curious about final gravity and alcohol content.

        • sdmikev says:

          I make up my own recipes, based on a lot of early trial and error.  
          My stout I just made was based on recipes culled from around the internet for SN, like I noted, then I went from my own starting place and what I like to drink.
          Note, I ALWAYS use CA White Labs 001 ale yeast, and 7 pounds of liquid malt extract for my base, then alter from there.  Different hops, cracked special grains (Crystal, Black patent, etc..)
          For this, I used 2 ounces of Magnum in the boil for 60m, one OZ of Cennt for a half hour, one for the kettle finish and one whole flower Cascade in the secondary ferment for my dry hop.
          1 of the 7 pounds of ME was wheat, as well.

      I find there is too much foam to get a good reading for the OG that way. Not that I would spend $500 on such a measuring device either…

      • dragonfrog says:

        Sure, for the OG I put a sample in a graduated cylinder, letting it overflow and carry the foam away.  For the FG I put another sample in the graduated cylinder.

        I just mean in between – say if you want to know far along the fermentation is, to estimate the length of a diacetyl rest – you don’t need to know the gravity to the nearest single point.  For that sort of thing, I can easily eyeball it to within 2 or 3 points without extracting a sample, and that’s quite good enough.

    Hydrometers suck, for the reasons stated.  Refractometers need to be recalculated and adjusted for increasing alcohol in solution and will not give accurate readings as fermentation progresses.  

    A lot of homebrewers think that they can use a refractometer without applying the required mathematical correction and still make good beer.  This is the device for them.

    • uberbitter says:

      I agree hydrometers suck, but I don’t think that most of those homebrewers who find using a refractometer properly too bothersome will have $500 to shell out for this device.

    It’s amazing how something humanity has been doing for about 12,000 years now requires laboratory equipment.

    • foobar says:

      It doesn’t require laboratory equipment, but that doesn’t mean it isn’t useful.

      • retchdog says:

        yeah, i know. i’m just imagining folks buying all this kit, brewing two or three beers according to stock recipes, and getting tired of it.

        i have two stout variants fermenting right now, though they’re only a gallon each. my total equipment expenditure has been about $20. admittedly, $6 of that was for a hydrometer.

      How to measure specific gravity, c. 1669:

      “Take of spring water what quantity you please, and make it more than blood-warm, and dissolve honey in it till ’tis strong enough to bear an egg, the breadth of a shilling”

  6. Nagurski says:

    Probably overkill for hobby/home operations, probably quite useful at any commercial level from brewpub on up.

  7. Quibbler says:

    A hydrometer has to be one of the simplest devices to use. I have been brewing for 40 years and that is all I need to test the final gravity. Sometimes I use a refractometer  when mashing to test the conversion because they only take a drop to give a measurement.
