Moonraker,, I have made copious quantities of wine from Elderberries, unheated, with no ill effects. Comments please.....
Well, I can only refer you to the government scientists who put together the MAFF poisons book. It may be that fermentation also reduces low level toxicity but I am not sure on that. There are recorded medical cases of people suffering badly from ingesting raw juice and berries, notably diverticulitis in some people.
From reading, it seems the toxicity of the berries and flowers is lower than the leaves, roots and bark. But then with all plants levels of chemicals, including toxins will vary according to many factors such as season, location, soil type, species diversity etc. So, what may be OK for one person may not be for another, especially when we consider dosage (for instance what does not effect an adult, may well cause problems in kids). Like many toxins they may be rendered harmless by treatment but one should be aware of the potential dangers.
In the end we can eat what we wish, but generally we should show as much respect for wild plants as we do for fungi.
Perhaps the words of a famous herbalist will provide further evidence of the plants toxicity:
The first shoots of the Common Elder boiled like asparagus, and the young leaves and stalks boiled in fat broth, do mightily carry forth phlegm and choler. The middle or inward bark boiled in water, and given in drink works much more violently; and the berries, either green or dry, expel the same humour, and are often given with good success to help the dropsy; the bark of the root boiled in wine, or the juice there of drank, works the same effects, but much more powerfully than either the leaves or fruit. The juice of the root taken, mightily procures vomiting, and purges the watery humours of the dropsy...

I am sure you make delicious wine and I love elderflower champagne, so the processes involved and levels of toxins must be sufficiently reduced for consumption.
