5 Things I Wish I Knew When I Started Fermenting

Pepper Geek

Main takeaways
01

Weigh produce and brine in grams to calculate precise salt percentages (e.g., 800g × 2.5% = 20g salt).

02

Use an airlock lid to release gas and prevent oxygen ingress or pressure buildup.

03

Target 60–70°F for best flavor; colder slows fermentation, warmer can create off-flavors.

04

Leave about 1 inch of headspace to allow gas expansion and avoid overflow.

05

Try both brine and mash ferments; keep ingredients submerged or covered to prevent oxygen exposure.

Key moments
Questions answered

Why is weighing ingredients important for fermentation?

Weighing in grams lets you calculate the exact salt amount by weight (not volume), ensuring the desired salinity that favors lactobacillus and prevents bad bacteria.

How do you calculate how much salt to add?

Add salt equal to (total weight of produce + water) × desired salinity. Example: 800 g total × 2.5% (0.025) = 20 g salt.

What does an airlock lid do and why use one?

An airlock lets fermentation gases escape while preventing air from re-entering, reducing contamination risk and avoiding pressure buildup that can crack lids.

What temperature should I ferment at?

Aim for about 60–70°F. Cooler temps slow fermentation; warmer temps speed it up but can produce off or unpleasant flavors.

How much headspace should I leave in a jar?

Leave at least one inch of headspace to allow gas expansion and reduce the chance of overflow; tamp down ingredients if needed.

When should I use a brine ferment versus a mash ferment?

Brine ferments are simpler for keeping ingredients submerged but require weights; mash ferments (no added water) can be trickier and need careful removal of air pockets to avoid spoilage.

Importance of Weighing Ingredients 01:28

"It's really important to weigh your ingredients because salt and the amount of salt that you put into a ferment is critical."

  • Weighing your fresh ingredients, particularly for fermentation, is essential. Relying on volume measurements, such as cups or liters, can lead to inaccurate salt proportions, which are vital for a successful ferment.

  • Using grams (g) as a unit of measurement provides precision when calculating the amount of salt to include. For instance, in a cucumber ferment weighing 800g, achieving a 2.5% salinity requires exactly 20g of salt.

  • Different types of salt have varying densities, meaning a tablespoon of one type can weigh significantly more than a tablespoon of another type. Hence, weight measurement is paramount to avoid the risk of undesirable bacteria taking hold in your ferment.

Benefits of Using an Airlock Lid 03:13

"If too much pressure builds up inside, it can explode; nobody wants that kind of mess in their kitchen."

  • Using an airlock lid during fermentation allows gases to escape without letting air back into the fermenting vessel, which mitigates the risk of explosions due to pressure buildup.

  • Airlock lids come in various styles, ensuring that you can find a suitable one for your fermentation setup. Even a makeshift lid like a rubber band with a paper towel can work in some cases, but it exposes the ferment to air, which is a risk unless properly managed.

  • Keeping fermenting ingredients submerged with a weight can help avoid unwanted bacteria by protecting them from exposure while still allowing gas to escape naturally.

Monitoring Temperature for Flavor Development 04:39

"The colder it is, the slower the ferment will go; the warmer it is, the faster fermentation happens."

  • Temperature significantly influences the flavor and fermentation rate. The ideal temperature range for fermenting is between 60°F and 70°F, where flavors develop optimally.

  • Anything colder than this slows fermentation considerably, while overly warm conditions can lead to unpleasant flavors or spoilage.

  • Using a thermometer to monitor temperatures in your fermentation area is advised. Higher accuracy can be achieved using smart thermometers that connect to apps, providing insights into temperature fluctuations over time.

Head Space in Fermentation Jars 06:11

"I always recommend at least one full inch of head space regardless of what you're fermenting."

  • Headspace is the distance between the top of the ferment and the lid of the jar. Adequate headspace is necessary to accommodate gas expansion during fermentation.

  • Failure to leave enough headspace can lead to overflow, creating a mess. A rule of thumb is to leave at least one inch of headspace, increasing it based on the size of the ferment and the width of the jar’s opening.

  • Conversely, having too much headspace may expose the top layer of the ferment to mold. Techniques like tamping down ingredients can help manage gas buildup and free space.

Experimenting with Fermenting Techniques 07:52

"There really are pros and cons to both brine ferments and mash ferments."

  • It's essential to experiment with different fermentation methods, such as using a saltwater brine or a mash without added water. Each approach has its benefits and drawbacks.

  • A brine ferment often requires weights to keep ingredients submerged, as they might float during fermentation. Keeping everything submerged is critical to preventing mold and pathogenic growth.

  • Practicing with different fermenting techniques and understanding how they affect taste and safety will empower your fermentation skills.

Importance of Weighing Ingredients 08:24

"It's super easy; just make sure you weigh your fresh ingredients and the water before measuring how much salt to add."

  • Accurately weighing your ingredients is essential for successful fermentation. This includes both the fresh produce and the brine water.

  • Ensuring everything is submerged in the brine reduces the chance of air pockets forming, which are detrimental to the fermentation process.

Understanding Mash Fermentation 08:41

"A mash ferment is a little more tricky; I would say it's slightly more advanced."

  • While using fewer ingredients, a mash ferment requires more attention to eliminate oxygen.

  • You must press out any air pockets before starting the fermentation to avoid exposure to oxygen, which can spoil the process.

Preventing Oxygen Exposure 09:09

"You can prevent exposure by creating a cover, such as a piece of parchment cut to size."

  • A surface mash may be exposed without liquid, making it vulnerable to oxygen.

  • Creating a cover for your ferment, like using a piece of parchment paper, can effectively block air exposure while fermenting.
