Q: I have a nut allergy. Is it safe for me to drink wines that have "nutty" notes?—Steven, Newtown, Pa.
A: It’s not uncommon for consumers to be curious about where all those different flavors and aromas in wine come from. A wine might taste like cherries or chocolate or nuts, but it’s just fermented grape juice in the bottle.
We might find nutty aromas such as toasted almond, hazelnut or walnut in a wide range of wines, especially Champagne, Sherry and wines that have aged for a decade or more; in terms of winemaking practices, nutty aromas are most frequently associated with sur lie aging and oxidative winemaking practices.
But more to the point of your question, that’s all to say that there are no nuts or nut products in traditionally made wine. While a “nutty” wine might share its aroma with that of actual nuts, it won’t trigger a nut allergy.
