88 WINES&VINES January 2018 WINERY & VINEYARD EQUIPMENT curately measure. If your toler- ance for oxyge n is not that critical, and you want to know about oxygen in your wines, this meter is one of the most cost-ef- fective ways of having that func- tionality in your winery. The meter has a straightfor- ward calibration procedure: Hanna Instruments includes the pH 4.0 calibration buffer as well as a pH 3.0 buffer for the wine industry. That assures the best linear range in the region most wine pH readings are found. The screen icons on the meter give the probe function and condi- tion, and there are reminders for calibration and an extensive log- ging function. The probes have an internal temperature sensor for temperature compensation free- ing space in the test beaker. Electrical conductivity pro- vides one of the easiest means for a small to medium-sized winery to perform a better analysis of cold stability. The EC probe is im- mersed in the wine during the cold stability trial and a reading is taken at specific times. Hanna Turbidity Meter One of the most cost-effective solutions for heat stability testing In the turbidity meter, a spectrom- eter measures the amount of light compensated for color that pass through a liquid for a specific dis- tance. Light scatters due to sus- pended particles in the wine or must sample (such as glucan, tan- COMPARING RESULTS FROM LAB INSTRUMENTS Acetic Acid g/L Sample 1 Sample 2 Sample 3 CDR WineLab 0.62 0.72 0.58 Megazyme 0.62 0.63 0.63 ETS Laboratories 0.61 Alcohol % by Vol Sample 1 Sample 2 Sample 3 CDR WineLab 13.2 13.3 13.4 Megazyme 13.2 13.1 13.2 Rudolph 20C 12.98 12.99 12.99 Ebulliometer 12.96 12.97 12.96 ETS 20 C 12.98- 20C 12.94 – 60F Brix Sample 1 Sample 2 Sample 3 Rudolph 1.54 1.00396 Hanna Instruments 1.5 ETS Laboratories 1.5 1.00395 Glucose + Fructose g/L Sample 1 Sample 2 Sample 3 CDR WineLab 0.3 0.3 0.4 Megazyme 0.331 0.332 0.35 ETS Laboratories 0.3 Heat Stability Sample 1 Sample 2 Sample 3 Hanna Instruments 5.78 5.79 5.8 ETS Laboratories 6.5 NTU Micro Testing Sample 1 Sample 2 Sample 3 Arrow Lab Solutions 1 2 0 Gomberg, Fredrikson & Associates Market Research For e Wine Industry Products include: · The Gomberg-Fredrikson Report: "The Executive Marketing Report of the Wine Industry" · WineData Wine Pricing Report: Competitive supplier pricing for more than 13,400 products · Distributor Market Service: Gain a competitive advantage by analyzing your position in the wholesale market www.gfawine.com • 707.940.3922 • inquiry@gfawine.com We perform extensive market research and data collection to create the wine industry's leading databases and reports
