Measuring TA in a Wine with a pH Meter (The Home Winemaking Channel)

This seven-minute video, shows a titration method of measuring TA in a wine but rather than using an indicator solution and a visual color change, we are using a pH meter to verify when enough NaOH has been added to reach a pH of 8.2. Once the amount of sodium hydroxide needed is known, a simple calculation can tell you the TA of your wine. This method is easy to do at home.

Testing

Malolactic Chromatography Testing (MoreWine!)

Malolactic fermentation (MLF) is a winemaking process involving a special bacterial strain that metabolizes the malic acid naturally found in grapes into lactic acid. Lactic acid is a weaker acid than malic acid so the effect of this conversion is a decrease in the wine’s acidity along with a corresponding raise in the wine’s pH. As an additional benefit, the bacteria also add mouthfeel and complexity to the wine.

Bulk Aging (WineMaker)

Aging your wine is not the most exciting winemaking topic, but it is a critical topic. Aging wine is considered from the time after your fermentation is completed through the time spent in the bottle before consumption. The three basic goals of aging your wines are to assure stability, to correct a flaw or fault, and to evolve the wine style by increasing complexity, flavor, and aroma.

Getting Closure: Corkers and Cork Sizing (WineMaker)

Properly sealing up your wine is the last great task at hand before laying down bottles. Making informed decisions on what size and type of cork suits your needs best and using the right tool can make a world of difference in its age-ability. In the April-May 2020 issue of “Beginner’s Block,” we covered the various closure options that are available to most winemakers and special considerations for each.
