Water quality parameters were measured at CDC. pH was measured with a Fisher Scientific Accumet Research AR25 pH/mV/°C/ISE meter. Turbidity was measured with a Hach model 2100N turbidimeter. Specific conductance (SC) was measured with an Oakton CON 100 conductivity/°C meter. Total hardness measured using a Hach hardness test kit and AL-DT digital titrator. Alkalinity was measured using a Hach alkalinity test kit and AL-DT digital titrator. Total iron was measured with a Hach DR/2400 spectrophotometer and FerroVer iron reagent. Total organic carbon (TOC) and dissolved organic carbon (DOC) were measured using a Hach TOC reagent set and Hach DR/2400 spectrophotometer. Water samples were prepared for DOC analysis as described previously [12 (link)]. Total suspended solids (TSS) were measured according to Methods 2540D in Standard Methods for the Examination of Water and Wastewater [28 ].

A Fisher Scientific™ Accumet™ Research AR25 pH/mV/°C/ISE Meter calibrated with buffer solutions (pH 4.0 and 7.0) was used to measure pH of vine tea infusions. A Minolta CR‐300 Chroma Meter calibrated with a standard white plate (L* = 96.77, a* = 0.45, b* = 2.37) was used to measure the reflective color of vine tea infusions in CIE L*a*b* (CIELAB) system. Vine tea infusions (30 ml) were pipetted into glass test tubes which were placed in a special support for liquids (CRA‐70, Minolta Co.). All samples were measured in triplicate. Statistical analyzes were performed using JMP® Pro 11.0.0, and a 5% significance level was used.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
