Question: My wife has gallstones and she is on a gluten free diet. The sulfites in the wine and sugar in the grape juice don’t agree with her at all. She reacts immediately in terrible pain. Is it ok for her to dilute the wine in water for the arba kosos and if yes how much water to how much wine.

Answer: One may only add water to the extent that the wine – or grape juice – can still be drunk as wine and served to guests that way.

Regardless, the water may never be 85.7% or more in the mixture (assuming no water was added by the company). One should ideally machmir that the water should always be less than 75%.

Regarding adding other drinks, they may not be more than 50%.
