Many of you may be familiar with the work of Johnny Drejer (Drecon.dk). For those that aren’t please visit his site and familiarise yourselves with his Hydrometer method.
Like Johnny I offer no guarantee that my readings are 100% accurate and I can only use already published results as a baseline for mine. Also, like Mr Drejer I am not doing these experiments in order to call out “bad” or “good” rum or individual rum companies. I am doing this to inform and also to improve my own reviews.
