Hi,
I'm a virgin wine-maker planning his first 3-5 gallon batch sometime this week. Though there seems to be some debate on the topic, I know from my relatively brief foray into brewing these past 2 years that different mineral profiles will invariably alter the character of a beer. What I don't understand is how this principle can't or doesn't also apply to winemaking? Wouldn't using local tap water, in addition to potentially stalling fermentation and imparting off flavors, introduce unwanted variability to a wine recipe, making attempts to replicate the recipe in other locations with different chlorine/bicarbonate/mineral profiles difficult, if not impossible?
So...I was wondering. Does anyone know if there is a "standard" profile that professional winemakers utilize to mimic the waters found in, let's say, champagne, burgundy, etc? Or is the argument, as WIP pointed out, that wine musts get all necessary minerals/water from the fruits and only the fruits? How did they do it in the 'old days' when distillation was not accessible to the average winemaker? Did they even dilute the fruit with water or just ferment directly from freshly squeezed grape juice?
