I would think that if the lime and lemongrass are not strong you could just enter it as a blonde.
But I don't compete much.
I had not considered that. This particular beer will be kegged in the next couple of days so I will have to make a judgement call on the strength of the lime/lemograss and consider some aging time as a mellowing factor... I may just go with specialty to be safe since I also have an american wheat that I might enter and would end up in the light hybrid category.
"Some versions may have honey, spices and/or fruit added, although if any of these ingredients are stronger than a background flavor they should be entered in specialty, spiced or fruit beer categories instead."
