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
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
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
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
Phenolics and Cider
What exactly are phenolics? Are they tannins? I don’t think there a simple answer. If I told you there are two basics compounds, flavonoid and non-flavonoid types of phenolics, would that clarify it? It didn’t for me but, chemistry wasn’t my favorite subject in school. If I broke down the flavonoids into anthocyanins, flavan-3-ols, and … Continue reading Phenolics and Cider
Fermentation Stages of Yeast
It is common to talk about fermentation in stages and often there are three stages identified. If you are talking about a wild or natural fermentation, those stages might be how initially non-Saccharomyces strains start the fermentation. This is followed by Saccharomyces yeast that complete fermentation. The final stage is maturation where Brettanomyces strains often … Continue reading Fermentation Stages of Yeast
Apple Peel Preparation
I have been harvesting and including apple peels in my hard cider for several years. As I have noted in other articles (see the tips page), peels are an excellent way to enhance the organoleptic properties of your hard cider. Want a darker hue to your cider, include peels from red apples in your fermenter. … Continue reading Apple Peel Preparation
Yeast Starter for Cider
A yeast starter is used to increase the biomass of a yeast and to ensure the yeast cells are healthy and ready to ferment. It is how you grow more yeast cells to ensure you have enough for a robust ferment and to ensure the yeast cells you are using are healthy and full of … Continue reading Yeast Starter for Cider
Yeast Propagation for Cider
Whether you use commercial yeast or wild yeast, you really should be thinking about yeast propagation. Yeast propagation is the process of taking a small yeast sample, usually from a plate or slant and growing it until you have enough to pitch into your juice to make cider. You might be thinking, that sounds like … Continue reading Yeast Propagation for Cider
Nutrient Deprivation: Keeving
Keeving is a process that seeks to remove nutrients needed for fermentation in order to create residual sweetness. Yeast need nutrients and vitamins to ferment and while they are good at finding or creating many of these nutrients, it only takes the loss of one to stop the process. Keeving is a process that removes … Continue reading Nutrient Deprivation: Keeving
