The refractometer is a tool I wouldn't be without on brewday. So much easier to take a gravity measurement. Couple drops on the lens and you're set. It would be sweet if they could be used for post-fermentation measurements.

If you're extract brewing, a refractometer is a giant waste of cash. If you're AG brewing, a refractometer can be very helpful.

If you are an all-grain brewer, a hydrometer is equally helpful. Either a hydrometer or a refractometer is essential. You need a way to measure gravity, while they are used differently, neither does the job better than the other.

I used a refractormeter for the first time on my second all-grain this week. It really helped me hit my desired gravity because I was able to take readings while the wort was boiling allowing me to see the gravity raise as the wort boiled down. Without it I would have had a hard time seeing where the gravity was headed. really nice to see the gravity in your wort in all the brewing stages.

I use my refractometer both on unfermented wort and fermenting wort and have found it to be very accurate. I use the refractometer tool in Beersmith during ferment to find my current SG and it's always within 1 point of the reading taken by a hydrometer. Far better testing one teaspoon than chucking 100ml from a trial jar down the sink.

No you drink that 100ml

I'm afraid this flies in the face of my experience. Let me list the steps for using each implement, then "we'll do the math".

Hydrometer

1. Remove a 100ml sample of wort - enough to fill the test jar three-quarters to the rim.
2. Refrigerate the sample until the heat won't shatter the hydrometer - approximately ten minutes, even in the freezer.
3. Immerse the hydrometer.
4. Spin the hydrometer.
5. Read the meniscus.
6. Repeat steps 3-5.
7. Record the reading.

Refractometer

1. Remove two drops of wort - approximately 0.5ml.
2. Place drops on refractometer lens. Close lens.
3. Peer into eyepiece. Read the blue line.
4. Record the reading.

Gee, what do you think?

I think the hydrometer is a waste of time, wort and effort in the brewhouse. For example, how can you sample the tailings of your sparge runnings with a hydrometer? You simply can't, neither as quickly nor as effectively as with a refractometer. The refractometer is infinitely more useful in the brewhouse. In the fermenting room, not so much. But in the brewhouse, only a lunatic would continue to use the hydrometer if offered a refractometer.

You are, of course, entitled to your opinion.

Regards,

Bob

So not true! The refractometer is accurate (with alcohol present) if you know your starting SG and do a calculation. I use Beersmith. Just plug in the info and presto! Also, checking with water before use is not a big deal at all. Seldom do I have to adjust anything. AFAIAC why waste good beer taking SG readings with a hydrometer when a refractometer only uses a few drops?

You're right Bob, I am entitled to my opinion, which your distorted comparison and compilation of irrelevant characteristics doesn't change.

mod edit- NO personal attacks

You are, of course, entitled to your delusion.
