We are a 1,500 case winery that sells through the tasting room and will begin shipping over our website next year. We’re located in Texas, where car trunks routinely reach 2,000 F in August, and the A/C blows at sub-arctic temperatures (I bow down and give all my praise to the inventor of modern centralized air conditioning).
To handle the shipping extremes and the heat of the Southwest, we need to insure that our whites are protein stable. We would like to add nephelometry to our standard operating procedures for heat stability tests. We currently heat samples with various bentonite additions in a digitally controlled dry bath, and monitor the outcomes. While the visual technique is fine, I would prefer the greater guarantee of a dependable turbidity meter giving me NTU’s on the samples.
Any advice ya’ll could give me on a simple yet dependable turbidity meter would be a great help.
I’ve been happy working with the benchtop Hanna NTU meters in the past, so my vote would be for them. I have never used the handheld meters, so I cannot give any advice on them. Good luck.
