We chose the premium tour which is the same just as the standard but with premium tasting (€15 each, you get four rather than three tastings and each tasting is aged).
Great tour (not overly long) which is very informative, helping you understand the overall processes, differences and comparison to standard wine making.
Tastings were very good and of a good size.
We also had the tapas option which is a little overpriced.
Overall, very good and worth a visit if you like sherry.
