The wine has a bit of fizz, is this a problem?
If it is a Chasselas or Vinho Verde, it's normal and deliberate.
Very slight effervescence in still wine is not really a fault, rather it is often a result of slightly incomplete malolactic fermentation when the wine was bottled, or filtration choices.
The flavour and aromas of the wine are in no way affected.
If the wine is left to breathe, this will usually disappear before consumption, but if not, a very quick and simple remedy is to apply a vacuum to the bottle for a few minutes - very easily done using one of the wine-saving devices such as a Vacu-Vin. Or carafe the wine.
