Refractometer Joke!

i find it very unlikely that the little sample will ferment at the same rate as the big fermenter. they are too dissimilar; totally different dynamics of gas exchange, just for a kickoff

Thank you Nesto for the clarification!

That's quite likely I guess, I'll try anyway and post the results.
I drew a sample from my current brew at 1.014 and have kept that strapped to the fermenter.
So far it's dropped to 1.012 but I haven't checked the fermenter gravity again.
I will do that tonight and see how they compare.
