Non-Saccharomyces Yeast: Lachancea thermotolarens

Cider Making Results Using Lachancea thermotolarens

I tested 3 samples of the strain Lachancea thermotolarens from the USDA last year. Lachancea thermotolarens is a very interesting yeast and I suggest reading my overview if you want to explore it in more detail. I also explored Pichia kluyveri, Candida zemplinina, and Hanseniaspora uvarum. Just search non-Saccharomyces on the site or look for … Continue reading Non-Saccharomyces Yeast: Lachancea thermotolarens

Non-Saccharomyces Yeast: Pichia Kluyveri Results

Results of cider making using Pichia kluyveri yeast.

I obtained 11 samples of non-Saccharomyces yeast from the USDA and have been conducting trials for my hard cider batches. Three of those strains where Pichia kluyveri. If you haven't read it, I would encourage you to review my overview of Pichia kluyveri and the other strains. Just search non-Saccharomyces on the site or look … Continue reading Non-Saccharomyces Yeast: Pichia Kluyveri Results

Cider Yeast: Classifications

Yeast Classification

Scientifically, yeast are identified by a classification methodology. They are part of the fungi kingdom and they will have different families and orders(1). For alcoholic beverages makers, like hard cider makers, we usually focus and talk about three classifications for yeast. The first and highest level is the genus. Saccharomyces is a genus of yeast. … Continue reading Cider Yeast: Classifications

Cider Fundamentals: Sugar

Cider Fundamentals - Sugar

Sugar is a fundamental element of making hard cider. Without sugar, yeast couldn’t ferment juice and produce ethanol so we wouldn’t have cider. We also wouldn’t have vinegar because vinegar is formed from the ethanol produced by the sugar. Isn’t it interesting how a single simple compound can have such a dramatic impact on human … Continue reading Cider Fundamentals: Sugar

How Nitrogen Impacts Cider Fermentation

Nitrogen and Cider: The Impact

In other articles, I’ve noted how nitrogen is one of the key compounds yeast need to turn apple juice into hard cider. It’s essential for protein synthesis and protein is needed to transport sugar into the yeast cell. Sugar creates the energy, ATP, needed for cell function and reproduction or what we prefer to call … Continue reading How Nitrogen Impacts Cider Fermentation

How Yeast Reproduce

Yeast Reproduction: Asexual Vs Sexual

As cider makers, we tend to think of yeast as our partner in producing wonderful hard ciders. We might inoculate with commercial strains or let the natural microflora go to work. Either option, if you are like me, you associate yeast with fermentation and the ethanol it produces. But, yeast don’t care about producing ethanol … Continue reading How Yeast Reproduce

Cider Nutrients: The Need for Nitrogen (YAN)

Cider Nutrients: The Need for Nitrogen

Many books and articles that you read on fermenting wine talk about how you need to add nutrients and specifically nitrogen to ensure a healthy ferment. While lack of other nutrients can slow or stop fermentation prematurely, nitrogen is considered the number one cause for wine fermentation to slow or stop. This is because nitrogen … Continue reading Cider Nutrients: The Need for Nitrogen (YAN)

Yeast Derivative Products (YDPs) & Aroma

The impact of Yeast Derivative Products on Aroma

Yeast Derivative Products (YDPs) can aid with fermentation by providing nitrogen and nutrients and with clarity by binding with colloidal compounds. But recent research has been focusing on how they can impact aroma. Remember that YDPs are just inactivated yeast developed to provide specific reactionary compounds. YDPs are made by using heat, enzymes, or even … Continue reading Yeast Derivative Products (YDPs) & Aroma

Cider Words: Yeast Derivative Products (YDPs)

Mālus Trivium Page Top

Yeast Derivative Products (YDPs) can aid fermentation, turbidity, and aroma. Have you ever heard of Yeast Derivative Products (YDPs)? If you are exposed to the wine industry, you have probably come across them as they are becoming more widely used in that industry. Rarely do I hear about there use in cider. I should clarify … Continue reading Cider Words: Yeast Derivative Products (YDPs)

What is cider yeast?

What is cider yeast?

It seems like a simple question and yet it’s actually a very complex one. For one thing, yeast are found about everywhere and there are thousands of different types of yeast. Should we therefore consider the yeast found on the apple as true cider yeast? What about the yeast found on the equipment used to … Continue reading What is cider yeast?
