Malic Acid Test Strip Kit, 0-500 mg/L, 10 Tests

These test strips are easy to run, and give an accurate reading. I am giving this review 5 stars because I had a quick question regarding the test results and contacted the company. Their customer support was excellent. They responded to my email with a return phone call within 5 minutes, and spent close to 1/2 hour on the phone going over wine chemistry. They even emailed me a few articles for reference. I would highly recommend purchasing from this company

If you need to know whether your malolactic fermentation is finished, this can probably do the job. The test output ranges from 0 mg/L malic acid to 500 mg/L. You can pretty confidently determine a zero or near-zero point, but the 30 mg/L to 500 mg/L range is not well-delineated. You shouldn't plan to use this test to quantify malic acid levels, just to determine presence / absence.

Most economical way to monitor Malolactic Fermentation. I found when strip dries is where most accurate color comparison can be apparent.

This is a total rip off. The range that this little strip puts you in is not even a useful indicator. You could use it for "yes" or "no", but if you want any accuracy at all you have to get it the old fashioned way.

My first time using this product and my starting malic acid in my chardonnay was >500 but after MLF it was 0-30 and completed! expensive but you know if your chemistry worked

If you're a small winemaker you can do paper chromatography (messy, complicated, takes time, nasty chemicals) or send your wine to a lab. Until now. With these test strips you can get a virtually instant result. Expensive, but worth it.

It does the job. Good as a reference.

These are great for testing your MLF completion - I’m so glad they are on Amazon...my local wine making supply store doesn’t carry them!

Good product
