Key numbers to remember regarding carbonation While some people enjoy their hard ciders still or without much noticeable carbonation, others enjoy some bubbles or even sparkling. The fermentation process under open atmospheric conditions at 21C (70F) will naturally have around 0.85 volumes CO2. You may remember from my Mālus Trivium on Volumes CO2 that the … Continue reading Key Carbonation Numbers

Respiration versus Fermentation
What is respiration and how is it different from fermentation? Have you ever heard that oxygen is bad and to avoid oxygen exposure when fermenting hard cider? It is or at least it can be.

Yeast Impact on Sugar and Acids
Yeast impact on residual sugar and acid in cider. While the research by M. Lorenzini and associates was done to assess the impact of yeast on volatile compounds in hard cider(1), I found it interesting for another reason.

In another post on hard cider color, I explored how to make what I call silver … Continue reading Exploring the Colors of Hard Cider
The Impact of Fruit Ripeness
Fruit ripeness can impact a variety of compounds. Ripeness is usually associated with sweetness so confirming that apple cultivars have higher sugars and lower malic acid as they ripen(1), makes sense. It’s always good when what we think it logical is confirmed by science. However, I found it interesting that when O. Laaksonen and associates … Continue reading The Impact of Fruit Ripeness
