How DUNDER Amount & Age Impact RUM Flavors! @RobynSmithPhD

Uploaded November 2022 | Updated September 2026, 5 days ago

I made four different rums using 20% and 40% young- and aged-dunder in the fermentations to understand how the amount and age of dunder impact the flavors in rum. Now let's taste them side-by-side!

$What temperature should you distill at? Boiling point as a function of ABV! I used a graph of the boiling point of ethanol and water mixtures as a function of ethanol concentration to determine what temperature I should set my air still to for a spirit run based on the ABV of the low wines in the still. And the calculation worked really well for me! So I decided to convert this graph from units of mole fraction and kelvin to units that are more distiller friendly: ABV and celcius/fahrenheit! Please note, Im not saying that every single still will start producing spirit once you set the pot temp to the boiling point of your liquid. If you have a very crude still with minimal reflux, like an air still, then it probably will match up beautifully (like it did for me). But if youre still has any significant reflux (like a long neck), it will most likely need to be set hotter in order to provide enough energy for those vapors to get over to the condenser. These boiling point values are good starting points though! And if you dont monitor the temp of your pot, dont worry! Its not necessary for distilling! *Original graph:* https://www.researchgate.net/publication/259470569_First_Steps_into_Physics_in_the_Winery *Graph and table on Patreon:* https://www.patreon.com/posts/what-temperature-109823237?utm_medium=clipboard_copy&utm_source=copyLink&utm_campaign=postshare_creator&utm_content=join_link Support on Patreon: https://www.patreon.com/thisblogsneat Read the blog: https://www.thisblogsneat.com/ Get NEAT merch: https://www.thisblogsneat.com/shop-merch Get featured bottles: https://www.thisblogsneat.com/bottle-library Shop my Amazon storefront: https://www.amazon.com/shop/fitness_robyn Follow on Instagram: @ThisBlogsNEAT$
