I'm not sure but pretty sure those lists come from all the brewers here and are being used in our recipes, so we the recipe builder categorize our beer our self, and it pulls the ingredients from each recipe. so if a category is blank it just means it hasn't been used yet and most of the new bjcp styles haven't yet because its so new
Yes, that would be a logical reason for the result, but the "Best Bitter"-style has around 60 recipes in the database, so I'm thinking there must be some technical problem causing the list to be empty.
Hi guys, thanks for reporting this. There was a bug in the way we were pulling hop statistics, which I've now fixed. Data should be showing up on that page again: http://www.brewersfriend.com/styles/best-bitter/hops/
