Sulfite Sensitivity and Calorie Claims at a Hotel
A four-star hotel with a spa and a 140-cover restaurant is revising its wine list for a health-conscious clientele. The F&B director wants a 'light and clean' section with calorie labels and a 'no added sulphites' claim. The head sommelier proposes a 12.5% ABV dry Riesling (residual sugar 3 g/L, total SO2 95 mg/L) and a 13.5% ABV Provence rosé (residual sugar 2 g/L, total SO2 120 mg/L). A guest with a documented sulphite sensitivity has told the restaurant that a 120 mg/L wine caused flushing and a headache, and asks for a wine 'without sulphites'. The spa manager wants to promote the Riesling as 'low calorie' at 80 kcal per 150 mL glass. The restaurant's menu currently states 'organic' and 'biodynamic' without definitions, and the wine buyer has been offered a 'sulphite-free' natural wine with no laboratory analysis. The hotel is in the EU and must comply with EU labelling and claims rules.
1. Calculate the energy per 150 mL glass for both wines and evaluate the 80 kcal claim.

Use ethanol density 0.789 g/mL and 7 kcal per gram of alcohol, plus 4 kcal per gram of sugar. Riesling at 12.5% ABV: 150 mL × 0.125 = 18.75 mL ethanol; × 0.789 = 14.79 g; × 7 = 103.6 kcal. Sugar: 3 g/L × 0.15 L = 0.45 g; × 4 = 1.8 kcal. Total about 105 kcal per 150 mL. Rosé at 13.5% ABV: 150 mL × 0.135 = 20.25 mL; × 0.789 = 15.98 g; × 7 = 111.9 kcal. Sugar: 2 g/L × 0.15 = 0.3 g; × 4 = 1.2 kcal. Total about 113 kcal. The 80 kcal claim understates the Riesling by about 25 kcal, or roughly 24%, and is not defensible. The EU nutrition declaration is per 100 mL, not per glass, so the menu should either use the official per-100 mL values or clearly state the calculation basis. 'Low calorie' is a regulated nutrition claim and is generally not available for alcoholic beverages in the EU; the hotel should avoid it and use a factual energy figure instead.
2. Explain the sulfite issue to the guest and staff and recommend a selection and communication approach.

Staff should not tell the guest that the wine is 'sulphite-free' or give medical advice. Sulphites are produced naturally by yeast and are also added; most wines contain some, and a claim of absence is difficult to support without analysis. The guest’s reaction to a 120 mg/L wine is plausible as a sensitivity, but total SO2 is not the same as free SO2, and other factors such as alcohol, histamine, dehydration, and individual triggers may contribute. The sommelier should apologise, show the analysed SO2 figures for the wines on the list, and offer the lowest-SO2 dry wines the hotel can verify, plus non-wine alternatives such as beer, cider, spirits, or no-alcohol drinks. The hotel should obtain laboratory certificates for any wine marketed as low-sulphite and train staff to say 'this wine has been analysed at X mg/L total SO2' rather than 'this wine is safe for you'. The guest should be encouraged to consult their clinician. A written allergen and sulphite policy protects both the guest and the business.
3. Advise on the 'organic', 'biodynamic', 'no added sulphites', and 'sulphite-free' wording.
Read the worked answer
Each term needs a different standard. 'Organic' should only be used for a certified organic wine or wine made from organic grapes, with the certifier and certificate available; in the EU, organic wine also has restricted SO2 limits, so the term is not a synonym for low sulphites. 'Biodynamic' should only be used with a recognised certification such as Demeter or Biodyvin, not as a style description. 'No added sulphites' may be used only if no sulphites were added and the analytical result supports the claim, including naturally occurring sulphites; keep the laboratory certificate on file. 'Sulphite-free' should be removed, because it is an absolute claim that is almost impossible to prove for wine. The menu should replace vague terms with verifiable statements: certification body, residual sugar, ABV, and analysed total SO2. The buyer should reject the offered 'sulphite-free' natural wine until it has a certificate of analysis. This protects the hotel from misleading-claim exposure and gives staff something accurate to say.
