refractor readings

[Cuckmere couple]

81% Brix
17% water

im presuming thats ok?

i did calibrate it last year with a mentor...do you have to re calibrate each year

 

[Beefriendly]

Usually not, but it's always good to confirm it is still accurate before using. I haven't had to adjust mine for ages. Virginia olive oil is good.

 

[Cuckmere couple]

and do you ignore Brix?

so my 17% is spot on?

It doesn't matter what measure you use as long as you know the water level is below the required number. Mine has a long line on the refractometer which is the iffy line. As long as it is above the iffy line I know I am ok!!!

17% is fine, to answer your original question.

How do you calibrate with virgin olive oil.... what would the reading be?
Thanks

27 if memory serves me well?
I check mine periodically
When I first got the refractometer I got a sample of olive oil took a reading and kept some of the oil so I have the same sample to use when I’m checking. In ten years I have never needed to alter it.

This site gives various reading for various oils for calibration.

Yeah well, a load of carp on that site as well as some good info. Difficult to tell apart though!
The 27% is the reading on the %water scale, not the Brix.
It's accurate, as this is one of the legal properties that virgin olive oil has to conform to.

I read the first two lines of that link and closed it.. temperature of honey makes no difference unless it is in extremes .

The first two lines don't talk about the temperature of the product (honey). Its just an article about calibration. The fourth line suggests you "Refer to your refractometer operation manual for your model's specific calibration instructions"

It is dog poop for me.. but crack on.
