Pectic Enzyme: Juice Application

Mālus Trivium Page Top

Impact of Pectic Enzyme - Juice Application Pectolyase, pectozyme, and polygalacturonase are three types of pectic emzymes or what are often called pectinases. These are naturally occurring compounds found in plants that breakdown the polysaccharide known as pectin. Pectin gives structure and strength to the plant cells. This structure is what make jelly and jam become … Continue reading Pectic Enzyme: Juice Application

Fermentation Stages of Yeast

The Stages of Fermentation

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

Mālus Trivium Page Top

5-caffeoylquinic Acid And it’s health benefits I like the motto, ”All things in moderation”. I enjoy my hard cider with dinner and for me, one is plenty. I love contemplating the aroma, the flavor, and how it goes with the food. What I also enjoy is that hard cider can have healthful aspects. It’s part … Continue reading Cider and Health: 5-caffeoylquinic Acid

Apple Peel Preparation

How to prepare apples peels for use in hard cider fermentation

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

Cider and Maceration

Mālus Trivium Page Top

Maceration and it’s impacts on cider making. The definition of maceration is to soften or separate. With regards to apples and pears, this process occurs after the apples have been milled or crushed but before the pomace is pressed. One of its key goals is to break down the pectin found in the fruit. This … Continue reading Cider and Maceration

Yeast Starter for Cider

The materials and steps to make a 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

Cider Words: Autophagy

Mālus Trivium Page Top

Autophagy: The process where yeast begin consuming themselves in order to stay alive during times of starvation. Have you ever heard of autophagy before? No? Don’t worry, I had never heard about it until I read chapter two of Molecular Wine Microbiology(1). Autophagy is strongly linked to autolysis, which I covered in an earlier Mālus … Continue reading Cider Words: Autophagy

Yeast Propagation for Cider

Propagating Yeast 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

Cider Words: Autolysis

Mālus Trivium Page Top

Autolysis: The decomposition of yeast cells. Why does the flavor of cider change when it ages? Part of those changes can come from bacteria or yeast. This micro flora can make malolactic fermentation (MLF) occur or a souring by Brettanomyces yeasts. However, one of the biggest impacts can come from the yeast that fermented your … Continue reading Cider Words: Autolysis

Nutrient Deprivation: Keeving

The Keeving Process

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
