    Yeah. I know what you're thinking. Not again! Why?!

    It was time for some internal disruption.
    • Unfortunately we've seen a drop in the industry using our scores since moving to 1-5 point system. We’d like to change that.
    • We know that many users miss the old 100 point system. In fact, the last poll we took indicated the most users preferred it. Perhaps we should've of listened, but we've learned a lot.
    • The 100 point system feels more BA-like and supports other projects that are in the works.
    • The Top 250 and regional lists became pointless and boring for most; same styles, from the same breweries.
    • We want to place more focus on the beer’s style and style education in general.
    Thanks to feedback from the industry, recent threads, and Society members, I stoked to announce the following updates.

    BeerAdvocate (BA) Score
    Unlike past versions, the math isn’t simple on the new BA Score.
    1. First, whenever a beer is reviewed we obtain the truncated mean. This means we examine all user scores for the beer, but then toss out an equal percentage of outliers on both ends.
    2. Next, we then obtain the beer’s weighted rank (WR) using the truncated mean. This entails running it through a custom Bayesian formula that takes the beer’s style into consideration; specifically the average and average number of ratings across all active beers within the style. This means that a beer is no longer pitted against all beers, but rather all active beers within its style.
    3. Finally, we apply the 100 point score using the beer’s weighted rank.
    A beer must have 10 or more ratings to be assigned a BA Score. And the BA Score is the only score displayed. You won’t find the beer’s average, truncated mean, or weighted rank. (read the update)

    Rankings
    All beers that meet our criteria (WR + activity) are now ranked within their listed style. Rankings are shown on beer pages and used to generate top rated lists for styles. Style data and rankings are updated daily.

    Top Rated Beers
    As we’re no longer comparing a beer against all other beers, we’ve opted to retire the old Top 250 beers, regional lists, etc. Instead, we’ll be focusing on where a beer ranks within its style and the new Top Rated Beers page reflects this new focus. We’ll eventually explore adding more interesting and useful lists, too. (read the update)

    Other than some cosmetic tweaks, that’s it for now. And @Mike is working to support these updates in the app, too.

    I’m currently rolling out the updates, so please be patient. Issues? Let me know. Otherwise I look forward to your feedback.

    Cheers!

    I like it - the pages have a cleaner look and the information is easier to see. I like how more emphasis is being place on styles that taking a beer and comparing it to everything across the board. Keep up the good work!

    Should keep the top 250 as a separate list along with the beer of fame list... it was a cool bucket list type thing for us old timers

    Can we still have an average score listed under the numeric score? I have no idea how the new score correlates with the number, at least show both. There are going to be a bajillon beers that have no score for my reviews too, since there are not enough ratings.

    Love that the top rated beers are by style now though.

    I agree with this. Love top beers by style now, but the top 250 lists were a really great feature and should be kept.

    Pages look nice and clean. I appreciate the reasons for the change. I will also miss the Beers of Fame and Top 250. Plus, I really like to know the average rating, since we rate 1-5, not 1-100.

    Not sure I like the top beers list. I see a beer with 1000 reviews rated as #1 but one with 13,000+ reviews is rated #11. To me this is flawed, the formula needs to take into consideration number of reviews. It is pretty clear a beer like KBS should be rated higher. When you take into consideration the number of high reviews it is proof the beer is world class. To me 1000 reviews does not indicate a beer is great.

    Look at KBBS, #1 Imperial Stout with under 800 reviews? That is better than KBS? I really think the formula needs to weight in the number of reviews in order to rank a top beer.

    I am already missing the top beers by state and country lists. This was a valuable tool when traveling to unfamiliar states/countries, giving me an idea of what beers to keep an eye out for.

    Totally agree. I have no way to compare my rating to the numeric score.

    Agree 100% with both of these points also. These features made BA stand-out vs. the other beer rating sites/apps.

    Speaking for the numerically inept, I am happy to see the 100 point scale back!

    Sure are a lot of 100s for the NE IPA style.
