How do I view spirit style subcategories? (ex. Bourbon, Sour Mash, Rye, …)

There are two ways to select a spirit style subcategory in Browse. After selecting a primary spirit style on the Home View, choose a subcategory from the scrolling banner at the top [1] or select the filters icon to choose a subcategory [2] while specifying further browsing filters.
