50 Furthermore, while it is apparent from Article 3(a) of Regulation No 1924/2006 that nutrition and health claims in general must not be false, ambiguous or misleading, that requirement applies all the more with regard to alcoholic beverages.

51 However, in a case such as that in the main proceedings, even if the claim at issue can be regarded as being substantively inherently correct in that it indicates reduced acidity levels, the fact remains that it is incomplete.

52 Thus, the European Union legislature was fully entitled to take the view that claims such as that at issue in the main proceedings are ambiguous or even misleading where they relate to an alcoholic beverage.

Consequently, restrictions may be imposed on the exercise of those freedoms, provided that those restrictions in fact correspond to objectives of general interest pursued by the European Union and do not constitute, with regard to the aim pursued, a disproportionate and intolerable interference, impairing the very substance of those rights (Case C‑22/94 Irish Farmers Association and Others [1997] ECR I‑1809, paragraph 27, and Joined Cases C‑20/00 and C‑64/00 Booker Aquaculture and Hydro Seafood [2003] ECR I‑7411, paragraph 68).
