I don't want to stir the wort before taking a sample. Yes. But alcohol changes the reading significantly and even with correction tables, the refractometer reading tends to not .
We have a complete guide with spreadsheet for finding your refractometer’s wort correction factor. A refractometer is a nifty brewing .
A refractometer can be used any time a hydrometer can. The reading you take right before pitching is your post boil reading. That is a good time to figure out your WCF. Take a . Before you can use your refractometer you must calibrate it with distilled or reverse osmosis (RO) water. Place a few drops of RO water on your refractometer lens and put down the cover. Look through the sight in a brightly . How to Use a Refractometer. Place several drops of the sample liquid on the angled prism. Seal the clear plate on top of it. Look through the eyepiece while pointing the refractometer at a source of direct light.
However, if used properly a refractometer can be a great tool to track specific gravity in place of or to supplement your hydrometer. This week, I take a look at refractometers, how they work and how an average home . For use with wort and beer you need to calibrate your refractometer to 1.000 with distilled water and then calculate the wort correction factor, which is specific to your . Refractometer is a fantastic asset to our hobby, get going with it , anything from five minutes into the mash, just for the added interest of things and how things change, during the mash every time I stir I do the SG with the refractometer, when in drain off I do the SG with the refractometer, I use it again as I sparge, and again with the pre . You need to make sure the wort is well-mixed (stir it just before drawing the sample), that there is no break material or hop matter on the refractometer slide, and that there are no air bubbles. I always take three samples and average the readings, and usually end up within 2 or so SG points of my hydro reading.

The downside though is it can be a time-consuming process because you have to cool your wort before actually using your hydrometer. Why you Need a Refractometer. One of the biggest benefits of using a refractometer is being . Looking for a deal on a refractometer? Homebrew Refractometer Deals, Discounts and Coupons. More Homebrew Finds! Last 50 Finds!

Our Top Posts – tips, how-tos, resources posts and more; Let’s be Friends! Recent . I'm at a loss. I have a hydrometer and a refractometer. I calibrated both using distilled water and both read 0 (1.000 and 0 Brix respectively), so I have to assume they are working correctly. When I measured OG of my last brew, the hydrometer read 1.071 (1.072 after temp. correction) while the refractometer showed 16 Brix implying an SG of 1.062.
refractometer for brewing
The procedure I use is to take a sample and read it immediately, then rinse and dry the refractometer stage before taking another sample so there is no partially evaporated wort on the stage to skew readings. If you are following these procedures and still getting different readings your refractometer may be defective. The "fuzzy line" phenomena of reading a refractometer is due to a cloudy sample. Clear wort before yeast pitch, no problem. Clear beer after fermentation and settling, no problem. Murky beer during fermentation with lots of solids, problem. Solution? Use a settled, degassed sample. That's the only accurate way to get a valid reading.
The refractometer should remain calibrated for a awhile and does not need to be calibrated before each use. Refractometer vs Hydrometer. The largest benefit to using a refractometer is the small volumes of liquid you need to measure gravity. I came across this really cool Refractometer Spreadsheet at the MoreBeer website. Refractometers work accurately when no alcohol is present. Therefore it is perfect for taking the initial gravity reading of your unfermented wort. However, once alcohol is present, figuring out the gravity of.
So I usually use a refractometer for my preboil and OG readings, then switch to a hydrometer for my post fermentation readings. . Help Support Homebrew Talk - Beer, Wine, Mead, & Cider Brewing Discussion Forum: . (even though cooled before reading) was getting near boil/hot break? Reply. D. dgez Well-Known Member. Joined Feb 25, 2008 . During the boil I used to cool samples on a spoon before dripping it on the refractometer. I was getting inconsistent and high readings. Now I understand that you should get hot samples onto the refractometer and close the plate asap before the water vapor escapes. Give the refractometer a couple seconds and it should be an accurate reading.A hydrometer requires the sample to cool down a bit before a proper reading can be taken, but with a refractometer you can just use a few drops and get a reading almost instantly. So once again we are talking about a tool which can save you time, and time is quite valuable to many homebrewers, especially those with a family that might need some .
With my refractometer, I have no problem getting a sharp line with wort, both before and after fermentation. If you're consistently getting a blurry line like this, it's likely caused by solids in the liquid that are preventing a good, clean . (being that 1 BRIX is 1 gram sugar in 100 grams water) i'm not completely sure on OG, i didn't measure and maybe the 4lb's of table sugar i didn't stir in are still at the bottom of the 10 gallons of apple juice..(could be why my ciders are taking so long to finish.something i'll have to think about, might still be a useful experiment) (and . +1 on refractometer less then effective after fermentation begins But that said, to calibrate a refractometer the common advice is to use distilled water. You just need a few drops to cover the measurement window so bring a cup of water to a boil in a sauce pan and then cover the pan with a clean cool lid, remove from the heat and count to 10.
You left it on the stir plate too long. It's likely the yeast ran out of fermentables and the stir plate kept going, introducing oxygen into the starter. This is hard on the yeast. You should get the starter off the plate at or just after high krausen. Either pitch it into a beer soon after getting off the stir plate or crash it right away. Traditional refractometers without ATC are calibrated to work at 68°F. The ATC function allows you to use the refractometer in an ambient temperature range of 50-86°F (10-30°C). Since your sample is just one drop, and will quickly adjust to the temperature of the refractometer, the temperature of the sample is irrelevant. Once the beer has returned to its targeted temperature, or a few degrees above, use a gentle stir to rouse the yeast and you may have to do it a couple times a day. The last thing you want is beat air into your beer. Beware, every time you open the fermentor you risk oxidation and infection, particularly true for buckets and other wide mouth vessels.

The woodlandbrew tables, only go up to FG refractometer reading of 12, but my imperial stout is 17.5. Site does give formula used, so have option to calculate yourself. But Vinolab - Alcohol from Hydrometer & Refractometer tool does it for you. Though it came up with z slightly higher ABV figure (by 0.5%) than a woodlandbrew table entry tried.
Usually, my digital refractometer readings make sense. But at the moment, successive/repeat measurements taken, on the same sample(s), always keep going up. Maybe from brix 17% to 22% over around 3 minutes. This is with samples from a fermenting, high gravity/ABV imperial stout. Present: OG. Stir plate: Stir plates are great for growing yeast starters quickly and for running forced fermentation tests. Stir plates are available for less than from numerous sources, or you can build one yourself. Hot plate/stir plate combinations are very useful, but are much more expensive. Very Serious Small Laboratory Results - Post-Fermentation The second set of measurements was taken after the mixture had been allowed to ferment for 1 week at ambient temperature. The mixture was measured at 72.0 deg F when samples were drawn off to measure with each of the measuring devices. Cheap Hydrometer: 0.999 reading, 1.000 adjusted for temp Triple Scale Hydrometer: .
So here's one that doesn't make any sense to me: Last few batches I've noticed that when I check the gravity of my wort after runoff, it's higher than after the 60-90 minute boil. Yesterday I brewed up a batch of Hefe' and decided to check it out carefully; I figured that since I use a refractometer while collecting/sparging/boiling and a hygrometer post-cooling, that the .
Refractometer (Brix & SG) Refractometers are excellent tools to determine the density of unfermented wort or must, providing quick and accurate readings with only a few drops of sample fluid. This handheld version is packed with features to make it . 【Zero-setting】Measure whether the clean water or pure water is 0.0% before using, and if it is not 0.0%，it will be zeroed first. 【Easy to use】Keep about 1 mm between dripped water or pure water and the top of the measuring slot, and the capacity is about0.3 ml.Press the"MEAS" key to display the value.
Perhaps a slimmer 2 inch stir bar would have worked better in this test, but the included 1 inch bar works just fine. Pictured is the stir bar only getting the start of a vortex, the stir plate was set to the max speed. I will be sticking with the included 1 inch stir bar for my starters. Yeast Starter Trials
Take one drop out (a glass rod or pipette) before adding each new sugar syrup addition, and get a refractometer reading. Those are useful data points, you should be able to see some progression. In this case the refractometer is much more useful here than a hydrometer, as the former is fairly sensitive to alcohol content while the latter isn't.
