As an expert sommelier and brewer, I can tell you that the time it takes for apple cider to turn alcoholic can vary depending on several factors. One of the key factors is the temperature at which the cider is stored. At room temperature, without any added sugar, it typically takes around 4-5 days for the cider to ferment and turn alcoholic.
However, if you want to speed up the fermentation process and boost the alcohol content, you can add more sugar to the cider. The added sugar provides more food for the yeast, which in turn produces more alcohol. If you choose to add more sugar, the fermentation process may take longer, ranging from weeks to even months.
The temperature at which you store the cider also plays a significant role in the fermentation process. Cooler temperatures slow down the fermentation process, while warmer temperatures can speed it up. If you want a quicker fermentation, you can consider storing the cider at a slightly higher temperature, but be cautious not to go too high as it may affect the quality of the final product.
It's important to note that during the fermentation process, the cider will go through various stages. Initially, you'll notice the yeast becoming active and converting the sugars into alcohol and carbon dioxide. This stage is often characterized by a bubbling or foaming appearance on the surface of the cider. As the fermentation progresses, the bubbling will subside, and the cider will start to clear.
Personal experiences have shown me that when making hard cider, patience is key. It can be tempting to rush the process or become anxious about the outcome, but allowing the cider to ferment at its own pace will result in a better final product. It's also important to ensure that the cider is stored in a clean and sanitized environment to prevent any unwanted bacteria or off-flavors from developing.
The time it takes for apple cider to turn alcoholic can range from 4-5 days at room temperature without added sugar, to weeks or even months if stored at a cooler temperature or with added sugar. It's important to monitor the fermentation process and be patient, allowing the cider to reach its desired alcohol content and flavor profile.
