The reason why No. 2 and No. 4 are not included in the Danish Temptation series of fruit-flavored beers is currently unknown. However, other beers in the series, including No. 1, No. 5, No. 7, No. 8 and No. 9, are all named with odd numbers. This may be because this series of wines are sparkling fruit wines made from apples as the main raw material and prepared through fermentation. Each of these models of beer represents a different taste and flavor profile. For example, No. 3 is apple flavor, No. 7 is elderberry flavor, and No. 9 is strawberry orange flavor.

In short, there is currently no definite answer as to why No. 2 and No. 4 are not included in the Danish Temptation series of fruity beers.
