I ordered a refractometer on ebay, one which supposedly has 0-40 brix and 0-25 alcohol %. I know the alcohol scale is totally bogus and was really getting it for the real brix reading. Well I get this thing and it only has a 0-25 alcohol % scale!! I mean WTF, that's total horse crap!
That doesn't mean anything without initial brix or gravity readings, how does it know my initial SG / sugar level?
Now I'm bummed. I contacted the seller and if I return it it will probably cost me shipping to get it back to them. Also there's the wait.
If I knew the scale they used, and if it's constant, maybe I could figure out the brix value it's reading. I mean if it's really 0-40 == 0-25 then it may be simple math.
