Hydrometer reading while sparging
|
|
It is agreed that sparging should not continue once OG reached 1.008 (or required volume has been reached). Trouble is the temperature at that point affects the reading by 10 points or so. Best would be to cool the sample but there is no time to wait for it to cool. In that case do I sparge untill the hydrometer reads 1.000 ?
- allowing for temp adjustment gravity would be +-1.008 ?

Palmer has a table for temp adjustment and specific gravity. check it out. it comes in handy.

I use a refractometer. It is so much easier when the wort is hot.

Yeah, a refractometer is almost essential for AG brewing, and one of my favorite purchases for the brewery. You can find them pretty cheap on e-bay.

Great find! You will not regret it. You can use glass eye droppers or pippettes to pull the wort for the sample. Also make sure you do the calibration exactly how it is described. Good luck!

+1 on the Refractometer, I just got one on ebay for 30, I can't wait to use it this weekend, using a hydrometer to monitor my sparge was getting too frustrating. I anticipating I will wish i bought one five years ago after this weekend. |

besides monitoring the sparge, what other tasks does a refractometer work better than a hydrometer ?
