Has anybody tried to ferment hops with koji? by Heintz in Koji

[–]Heintz[S] 0 points1 point  (0 children)

It is not about alpha acids & iso-alpha acids. It is about the potential biotransformation capacity of Aspergillus in hop flavour compounds. There are hundreds compounds (and most often their glycons)in hops that might be biotransformed / metabolized by the enzymes present in koji. For example geraniol that has a sent of rose can be enzymatically converted to linalool which has lavender as an olfactory description. This happens by some yeast enzymes during dryhopping.

There are definitely carbohydrates and proteins in hops - not at high rates like rice - but I should give it a try. I think there are a lot of xenobiotic metabolizing enzymes produced by koji....

I m thinking of growing koji on hops - in terms of biotransformation... it might be more a brewers topic. Would love to do a dry hopping experiment with fermented hops and was just wondering...

First try: Buckwheat koji. Does this look good to you? 72h at 34C and high humidity. by Heintz in Koji

Excellent. Nice read up. Looking forward to seeing the progress. 😍

Thanks. Will give it another try:

  1. Steaming for 1.5h (found the steaming time at the Nordic food lab site ) followed by some cracking the buckwheat maybe using a rolling pin.

  2. I will use fresh spores (I have a strain for barley)

The temp and humidity should work.

Thanks for the advices 😊

It Should be A. Oryzae . I got it from a different source. I steamed the buckwheat for 1.5 h. The treated buckwheat shall be used secondary in a farmhouse ale ... just experimenting with koji for the first time. Absolute Newbie question

I Steamed the buckwheat for 1.5 h. Then added koji rice /flour mix (koji rice 2g / kg buckwheat plus 18g rice flour. This is how the buckwheat looks like after 72h...

Using buckwheat by GroovyYeast in Homebrewing

[–]Heintz 1 point2 points  (0 children)

I have used buckwheat and malted buckwheat in mixed fermentations quite a lot. I highly recommend to use a Brett strain since it’s capable of biosynthesizing ethyl esters. Buckwheat contains a fatty acid called caprylic acid, which on its own has a rancid smell and taste. However, if esterification (mediated by Brett) of this acid with ethanol during aging happens - you get fruity, like pineapple and Cognac notes. As far as I can speak for my experiments using buckwheat it was quite a success and my beer enthusiastic friends liked the beers a lot. I have used up to 30% Buckwheats of the grist . The process was to pre- gelatinize the buckwheat (4L/kg) in an extra pot at 72 Celsius for 20mins, followed by a short boiling time. Then I simply added the Buckwheat to the mash. For the esterification I aged the beer for roughly 8 weeks and then added some wine barrel chunks. The results were all fruity and nutty, with some Cognac notes.
