The EBT (Electrolyte Balance Test) indicator typically shows wine red at the beginning due to the presence of certain acidic compounds in the solution, which create a red color. As the test progresses and the pH level increases, the indicator undergoes a color change to blue, signaling a shift to a more alkaline environment. This transition reflects the chemical reactions occurring during the test, indicating the balance of electrolytes in the sample.
The indicator commonly used in EDTA titrations is Eriochrome Black T. It changes color from wine-red to blue when transitioning from calcium ions to magnesium ions, helping to detect the endpoint of the titration accurately.

Eriochrome black T acts as an indicator by forming complex ions with metal ions such as calcium, magnesium, and zinc. It changes color from blue to wine-red in the presence of these metal ions, allowing for visual detection of the endpoint in complexometric titrations.
The blue label on wine bottles typically signifies a higher quality or premium wine. It can also indicate a specific region, grape variety, or winemaking technique used in producing the wine. The color blue is often associated with trust, loyalty, and sophistication, which may influence consumers' perception of the wine's value and quality.
I am guessing you want a dry red wine beginning with B? Will Beaujolais do??
