OK so there already is a Belgian Trippel IPA. It is called Piraat Ale. I haven't researched it any more than that, other than drinking a 750 of it tonight. It was all I had hoped for my own Belgian Trippel IPA. It was sweet as hell, tasting very much like an adjunct-filled belgian ought to. It was also extremely hoppy throughout. Hoppy in a Euro-grassy-hop way. Just like I expect my two ounces each of Saaz and Styrian Goldings (for 0.75 gallons) to make my Belgian Trippel IPA. I can only hope to achieve such awesomeness.
