I'm not sure I'd be describing ester profiles as "earthy." They are more associated with fruity characteristics. I find it sad that you say English IPA's as having "not too many flavour notes" and "single dimensional." While being very different and not as vibrant from new world hops, the traditional UK hops can have a very different yet great earthy, spicy, herbal characteristics. It probably means you haven't tried good fresh examples. Umm, might need to work on your brettanomyces pronunciation. Brett is usually frowned upon and unwanted in the wine industry. Brett will give every different profile depending on if it is used as a primary fermentation medium or secondary, as well as how old it is.
