Southernhighlander Posted April 1, 2019 Share Posted April 1, 2019 My grandfather used some kind of muck (bacteria?) to give his sweet mash white corn whiskey a buttery corn on the cob flavor and the same or a different muck to give his rum a butterscotch flavor. The stuff was nasty looking and he would add a little back set to it. Does anyone know what these mucks may have been? I found some info about it a couple of years ago on line for rum but now I can't find it. Thanks Link to comment Share on other sites More sharing options...
Foreshot Posted April 1, 2019 Share Posted April 1, 2019 Some part of it may be from Diacetyl. You can get that from short fermentation cycles. Yeast will create diacetyl during growth and process it once it's done. https://beersensoryscience.wordpress.com/2010/11/18/diacetyl-1/ <-- It's a little deeper than you need. If you google Diacetyl you can see more info. I'm not sure what part muck would play in it. It could be something totally different than diacetyl.

Silk City Distillers Posted April 1, 2019 Share Posted April 1, 2019 Butter Popcorn/Hot Buttered Corn - Like @Foreshot says - Diacetyl (this is what movie theaters put on your popcorn) - the muck/backset - likely lactobacillus - primary ester would be Ethyl Lactate (lactobacillus) - gives you a really creamy, buttery flavor. Ethyl Lactate can come across butterscotch as well, along with the other lactic acid esters. Any of the toffee, butterscotch, caramel, browned butter flavors - ethyl lactate plays a major role, and when paired with many of the oak flavors - vanilla, coconut - give you the big brown candy flavors. Flavors: Ethyl Lactate - Sweet, Fruity, Creamy, Pineapple-like with a caramellic brown nuance. Isobutyl Lactate - Buttery, Caramelic Isoamyl Lactate - Creamy, Nutty 1 Link to comment Share on other sites More sharing options...

bluestar Posted April 2, 2019 Share Posted April 2, 2019 Yup, sounds like secondary souring of the sweet mash after fermentation. Some consider this a "flaw" that sour mashing prevents. If done right, it can be very nice. Link to comment Share on other sites More sharing options...
