HOW TO COLLECT YEAST TO USE AGAIN

Summary

In this instructional video, Jorge demonstrates the process of yeast collection and reuse from corn fermentation. He explains how to siphon off the fermented liquid, clarify it using Turbo Clear, and then cold crash it to separate the yeast. The technique, borrowed from beer brewing, involves diluting the yeast mixture, refrigerating it to encourage sedimentation, and carefully siphoning off the clarified liquid. Jorge emphasizes the benefits of reusing a specific yeast strain for consistent results in distilling and provides tips for maintaining equipment cleanliness throughout the process.

Takeaways

• 🎥 The video is a follow-up on corn fermentation and focuses on yeast collection and reuse.
• 📝 Jorge, the host, explains the process of siphoning fermented corn into water jugs to separate the liquid from the yeast and other solids.
• 🍺 The terms 'trub' (for beer makers), 'lees' (for wine makers), and 'junk' (for moonshiners) are used to describe the settled yeast and other solids at the bottom of the fermentation container.
• 🚰 Jorge uses 'turbo clear' to help clarify the liquid and demonstrates how to siphon off the clear liquid, leaving the sediment behind.
• 🧊 The technique of 'cold crashing' is introduced, which is borrowed from beer brewing to clarify beverages by lowering the temperature, causing impurities to solidify and settle.
• 🌡 Jorge discusses the freezing points of different alcohol by volume (ABV) percentages and notes that high ABV solutions are harder to freeze.
• 🍾 The purpose of collecting yeast is to reuse a specific strain that produces desirable results in fermentation.
• 🔁 Jorge demonstrates the process of washing and separating the yeast through multiple cycles of dilution, shaking, and refrigeration.
• 🧪 The script includes practical tips, such as cutting the siphon hose at an angle to improve siphoning efficiency and cleaning equipment as you go to maintain hygiene.
• 📈 The video shows the progression of yeast separation over time, with visual evidence of the yeast settling and the liquid clarifying.
• 🍾 In conclusion, Jorge outlines how to store the collected yeast in a refrigerator with distilled water until ready for use in a future fermentation process.

Q & A

What is the main topic of the video?

The main topic of the video is the process of fermenting corn and collecting yeast for reuse, as demonstrated by Jorge.

Why is the viewer encouraged to subscribe and click the bell?

The viewer is encouraged to subscribe and click the bell to receive notifications every time a new video is posted.

What is the significance of the two buckets Jorge mentions?

The two buckets represent two different types of corn fermentation: popcorn and regular corn, both of which are being used to demonstrate the yeast collection process.

What does ABV stand for and what is its relevance in this context?

ABV stands for Alcohol By Volume, which is a measure of the alcohol content in the corn fermentation process.

What is the term used to describe the settled yeast and other solids at the bottom of the fermentation bucket?

The term used is 'junk on the bottom,' which can also be referred to as 'trub' in beer making or 'lees' in wine making.

What product does Jorge use to help clear the fermentation liquid?

Jorge uses a product called 'turbo clear' to help clear the fermentation liquid.

What technique does Jorge introduce for clarifying the yeast?

Jorge introduces the technique of 'cold crashing,' borrowed from the beer brewing industry, to clarify the yeast.

Why is the freezing point of the alcohol solution relevant in the yeast collection process?

The freezing point is relevant because it helps determine whether the yeast can be separated by freezing out the water content, leaving behind the yeast.

What is the purpose of diluting the yeast with distilled water during the cold crashing process?

Diluting with distilled water provides a medium for the yeast to separate from the solids and other byproducts, facilitating the collection of clean yeast.

How does Jorge ensure the collected yeast remains dormant and does not continue fermenting?

Jorge ensures the yeast remains dormant by cold crashing the mixture in the refrigerator, which slows down yeast activity and prevents further fermentation.

What is the final step in storing the collected yeast after the cold crashing process?

The final step is to add clean distilled water to the collected yeast, shake it, and store it in the refrigerator until ready for use in the next fermentation run.
