Have heard the word refractometer a lot. What is this? Should i buy one?
So it would take the place of my hydrometer?Setesh said:In addition to what forstmeister said, they can be used to take readings of really hot samples (like boiling wort) because you only need a few drops to test, and a few drops cools down WAY faster than enough wort to use a hydrometer would.
Very good explaination:
Hydrometers are great for measuring fermented wort. Most refractometers are not accurate for that. Plus the hydrometer is so cheap and easy to use it makes no sense to get rid of it.joecheberline said:So it would take the place of my hydrometer?
During the hot side of brewing, yes. I use my refractometer to take readings of my 1st and 2nd runnings and during the boil. I use my hydrometer to get my final reading on my cool wort. I also use a hydrometer for everything after fermentation has started because it's just easier (don't have to account for alcohol) and generally more accurate (same reason).So it would take the place of my hydrometer?
Are you brewing from extract or from extract kits? If so, you don't need one.Have heard the word refractometer a lot. What is this? Should i buy one?
Good point!Are you brewing from extract or from extract kits? If so, you don't need one.
If you are brewing all grain with a conventional mash tun and want to know how good of an extraction you have before you begin your sparge you sort of need one. You can brew for many years without one.
I'd argue the opposite- that one with the SG scale on the side is inaccurate for reading SG anyway and it'll just be confusing. I don't know of a single hydrometer where the brix scale and SG scale are correct at higher OGs.If you do get one, be sure its calibrated for beer. There are units out there calibrated for wine and meade. The scales ar different. Also, look for one that's dual scale... Brix and SG.
