Because cantaloupes have high pH, my guess is that the red speckles you’re seeing in a layer on top of your wine are bacteria colonies and no, they are not to be

A home winemaker details the four bench trials he conducted to adjust the acidity of a low-pH Sauvignon Blanc to show how the process is done and share the impact each approach had on the wine.

pH greatly affects the taste of wine as well as microbial stability. It can make the difference between drinking the wine or pouring it down the drain. Make sure you know when it should be analyzed and make the necessary adjustments.

Absolutely, I would lower your pH prior to aging. No matter how high the TA is, if you’ve got a high pH as well, you are putting your wines at risk for

A Word From the Publisher And the Wine Wizard is……. “When will my fermentation stop?” “Why did my fermentation stop?” One thing I can count on as publisher of WineMaker magazine is

Wine and grape juice is a naturally acidic solution. A pH reading has an inverse relationship with acidity, in that, the lower the pH measure, the higher the acidity. While a wine’s

Ask almost any commercial winemaker and they will say that pH is one of the most important – if not the most important – winemaking parameter. Even though TA is important for

You might be wondering why someone would want to bother tinkering with must when trying to get the grapes smashed and into the bucket is challenge enough.
