Firstly, I resurrected Rafael Arroyo’s beloved laboratory still, the birectifier, and it is incredible:
4/15/18 For Sale: Birectifier Beverage Distillate Analysis Kit ($900USD)
4/21/18 The Birectifier in Rum Manufacture (1945)
I have a large index elsewhere of birectifier case studies and background.
You can find Arroyo papers here:
12/6/15 Rafael Arroyo’s Lost Papers on Rum
9/7/19 Rafael Arroyo – The Lost Preface to Studies on Rum
This, I think, is Arroyo’s first report:
10/28/18 Arroyo’s First Report (1938)
These two papers I translated from Spanish with Circular 106 being of startling importance.
11/8/17 Arroyo’s Invitation: The Problem of the Ripening of Crude Rum
6/24/18 Circular 106, Rum Manufacture, Rafael Arroyo, 1938
I wrote quite a few background texts about Arroyo’s work as well as explorations of a few key organoleptic tests he used for rum evaluation:
