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

Cider: Taste versus Smell

What is the difference between taste and smell?

I often talk about taste and smell being the same and, I’m not alone. This is because the flavors or what is often defined as the taste of food and drink depends on aroma. To be more specific, the flavor is created by olfactory receptors in the nasal pharynx picking up volatile compounds (aromas) when … Continue reading Cider: Taste versus Smell

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 and Natural Sweeteners

Cider & Natural Sweeteners

The quest for a naturally sweet hard cider is like trying to find a four-leaf clover, something sought by many but only found by a few. There are a number of methods, like keeving and nutrient deprivation, that can be utilized. But, while these work, they are not always the simplest method and may not … Continue reading Cider and Natural Sweeteners

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

Aging Cider with Oak

Aging Cider with Oak

I did a previous experiment using heavy toasted French and American oak on a cider to see if we could recognize a difference in the aromas. This led to using oak more often and to even start experimenting with different wood, like maple, hickory, and birch. Wood is a great adjunct for cider. Besides adding … Continue reading Aging Cider with Oak

Hazy Cider: Colloids

Cider Clarity - Colloidal Compounds

If your hard cider is hazy, it has colloids. Cider colloids are a mixture of small particles or compounds that are insoluble and evenly suspended within your cider. Colloids are generally compounds made up of carbohydrates, color compounds, or proteins(1). The carbohydrates and color compounds are usually derived from the fruit. The proteins are usually … Continue reading Hazy Cider: Colloids
