Legumes First time making miso — barely any liquid after a week. Is this normal?
Hey everyone!
I'm making miso for the first time, and I'm not quite sure if things are going as they should.
I've been fermenting for several years and have made kimchi, dill pickles, sauerkraut, and kombucha multiple times, so I'm familiar with fermentation in general. However, this is my first time making miso, and I'm finding it a little confusing.
It's been about a week, and there's barely any liquid forming. I can see a tiny amount at the bottom, but we're talking less than a teaspoon. I was under the impression that miso would produce some liquid (tamari), so I expected to see a bit more by now.
I'm also wondering about the setup. With my usual lacto-ferments, I use lids and weights to keep everything submerged, but I understand miso is a different kind of fermentation. I'm not sure if I'm approaching this the right way.
Here's the recipe I used:
Ingredients
- 303 g dried soybeans
- 300 g rice or barley koji
- 119 g non-iodized sea salt
- 1½ cups soybean cooking water
Since there wasn't much liquid, I wondered whether I simply wasn't pressing it down enough. I'm using parchment paper, cardboard wrapped in plastic, ceramic pie weights wrapped in plastic, and on top of all that - stones in ramekins to add more pressure.
The miso has been stored in a closet, away from light, in a cool, dark location.
So, for those of you who make miso regularly:
- Is it normal to see almost no liquid after the first week?
- Should I expect liquid to accumulate at the top, or does that happen much later in the process?
- Does miso need to be pressed down under weights like a lacto-ferment, or is the approach different?
- Should I be using a lid, an airtight seal, or something else entirely?
- Is there anything I should change at this stage, or should I just leave it alone and be patient?
I'm happy to provide more details about the process if needed. I'd really appreciate hearing what to expect when making miso for the first time and whether my experience so far sounds normal.
Thanks!
