pH probes: Basic care and storage
When it comes to setting up your home wine lab, there is a lot to learn. You’ll discover that the proper care of something as basic and simple seeming as your pH probe will make a world of difference when it comes to producing reliable, repeatable numbers. Even if you don’t have access to any other means of wine testing at home, having a pH meter is a necessity.
Do
- Store your pH probe in the proper storage solution
- Calibrate your meter – and use fresh calibration solution each time
- Rinse the electrode before and after use. You may see salt deposits form – this is OK, just rinse them off too.
- Be gentle at all times
Do not
- Store your pH probe in distilled water.
- Mix any of your buffer solutions with one another. This may seem obvious but it’s easy to get a drop of one into the other if you’re not paying attention.
- Hit the pH probe against anything. This is especially important if using a stir plate and magnetic stir bar – don’t let it hit it!
- Pour buffer back into the bottle after use

Tips
Kimtech wipes are delicate tissues that reliably clean up liquid and small particulate from sensitive lab equipment such as pH probes. They’re a great addition to any home lab.
A probe can look clean but be contaminated with various coatings – this is why consistent cleaning and proper storage is very important for continued accurate readings.
You will need to replace your probe over time regardless of how well you take care of it, but the more carefully you clean and store it, the longer it will last.

Samples to be tested – a truly beautiful sight!
What analyses do we offer?
- Brix, pH, TA
- Free and/or total SO2
- Alcohol
- MLF
- YAN
- Sensory analysis
Why is analysis important?
- Knowing the Brix, pH, and TA of your juice sample is the most important first step pre-fermentation. Depending on these numbers you may need to acidulate (add acid) or ameliorate (add water) to your must or juice before initiating fermentation.
- SO2 levels will indicate how well protected your wine is. You may need to add more or less depending upon the reading.
- Alcohol % (ABV) is an important number to confirm, especially if looking to confirm the final number for a wine label.
- The presence of malolactic bacteria will indicate whether or not MLF has completed in your wine.
- YAN numbers will tell you the amount of yeast assimilable nitrogen levels will help you decide how much nitrogen/nutrients you may want to add throughout the alcoholic fermentation.
- Sensory analysis entails our highly knowledgeable and skilled staff conducting a taste test on your samples. This is especially helpful if you are looking to see how to improve upon your current wine, or how to sharpen your winemaking skills for future vintages.
pH and TA are important numbers to know as they will affect the entire winemaking process from start to finish
