Default Refractometer vs. Hydrometer Video


Don't mind the year old Flanders barrel in the background.

Pretty cool, makes me want a refractometer. What would be the easiest way to just pull a couple drops from a carboy though? Do you just take some with the baster put a couple drops in and taste the rest?

They make really long pipets that you'd dip in and hold your thumb over the end before pulling it out. A drinking straw would work in a pinch. I look at refractometers as fast and easy when you DON'T want to taste the sample. If you're going to drink a few ounces, you might as well go hydrometer. I didn't really want to recommend one over another because they both have their place, but I hope the video shows the pros/cons.

nice video. I would like a refractometer to make OG sample easier but was displeased with not being able to use it after fermentaiton. Thanks to this brew sheet I get to spend another $50. Thanks Bobby-M!

I know in your video you say 0-32° is good but is 0-70° okay as well? or too broad a range for our use?

Wow great vid...you convinced me.

Especially since I could make out the numbers on the refractometer through the viewfinder of your camera...I'm sure my eyes could see it as well naked.

Question...when drawing a pipette sample for preboil gravity, where it's come out of the mashtun @ around 150ish degrees, how long to you have to let the sample cool before dropping it onto the lens? You mentioned something about the refractometer temp adjusting...but will dropping hot wort on it damage it?

When I use my Refractometer, it just takes a drop from the wort to get a reading. That cools pretty quickly on the sample glass. I just drip the sample off my stirring spoon.

Very timely post. I expect my refractometer will arrive this week.

Do you just rinse off the lens between uses? How easy is it to clean?

Revvy,

the sample usually cools pretty dang fast -- like the time between extraction and placing 2-3 drops on the lens. Heck, it's a glass lens at room temp, so a couple drops of ~150*F wort won't hurt anything. Just make sure you get an ATC (auto temp control) one, and calibrate it with distilled water the 1st time you use it.

I got mine on eBay (my 1st and only purchase on eBay) for ~$15 on my second auction attempt.

You'll never go back to hydro's (well, except when you rack, you want to taste a sample, you want to compare refract v. hydro, you don't want to convert your Brix once fermentation starts). Heck, like Bobby says, both have their place, but refracto's are definitely worth it for AG brewing to test the runnings...

I just wipe it clean with a small cloth. You're only using a couple drops so it's really easy.
