This arti­cle is an addi­tion to the 2‑part How to Cure Vanilla Beans arti­cle.  A crit­i­cal stage in the cur­ing of vanil­la is the “sweat,” where the enzy­mat­ic process that devel­ops the vanillin takes place. The sweat box cre­ates an envi­ron­ment that holds the beans at the opti­mal tem­per­a­ture for this process. In the How to Cure Vanilla Beans arti­cle, I describe how to put togeth­er an ad hoc sweat box using a cool­er and hot water bot­tles. In this arti­cle, I will describe how I built the elec­tri­cal­ly heat­ed sweat box used to han­dle larg­er quan­ti­ties of vanil­la pods.

I occa­sion­al­ly get ques­tions from peo­ple who are grow­ing their own vanil­la and want to know the best way to cure the beans. Getting a good cure out of your beans can be a lit­tle chal­leng­ing, but hope­ful­ly, this guide will make it eas­i­er. It is essen­tial that vanil­la be prop­er­ly cured in order to obtain the desired aro­ma and fla­vor from your vanil­la beans. Processing vanil­la beans is a mat­ter of sup­port­ing both the vanillin devel­op­ment and the slow dry­ing of the bean in order to pre­serve it.

In Part 1, I explained how to har­vest and pre­pare the beans for cur­ing, and what equip­ment you’ll need. Next, we’ll go through how to sweat, dry and age the beans.
