    -> Poll #24 <- determined the that hops will be added at 60 minutes and 10 minutes. This poll will determine the IBU target. Note: The bittering model will be Tinseth.

    I recommend you think about the IBU levels in terms of the bitterness of outstanding Dubbels you may have tasted. If you haven't had any, I recommend paying attention to the discussion. If you want less than 15 IBUs or more than 25, write it in.

    When this poll is done, I will look at the data a few different ways to determine the central tendency. It may or may not be as simple as a plurality would indicate. There may or may not be a runoff. It all depends on the data.

    This poll will be open for 48 hours.

    If you have issues with or suggestions for methodologies used in this project, please send them via beermail. Let's keep the threads themselves on topic to the question at hand and not about how you would have asked the question differently. Lobbying for votes and intelligent discussion of each choice's relative merits is encouraged.

    Personally I like stronger beers to have more IBUs. Maybe that's just me.

    Most of the good commercial ones I know of (New Belgian, Ommegang, Chimay) come in around 20.

    Here's the thing: if you go with a higher IBU, and you subsequently decide it was too bitter, that can fade with time. In contrast, no amount of time is going to make your beer seem more hoppy. Therefore, if you are uncertain, err on the high side.

    This. And, take a look at BU:GU. I've gotten great scores with dubbels with a BU:GU ratio of 0.39. For this beer, that's >25 IBUs. So I voted 25.

    The three votes for 22 IBUs might want to switch to 20 or 25.

    Or not - this is so Binary that 23 might be a good compromise

    I would say, there is a little ambiguity about when strategic voting makes sense. It always makes sense in the "straight plurality" polls, but in cases like this, VikeMan has set out a harder task for himself by retaining the option to hold a runoff or whatever. I suspect (though I don't know) that he would prefer for people to vote their honest preferences rather than voting strategically, because it will help him make a more informed decision. Of course, you can still vote strategically, and it might even be rational to do so—maybe you care more about the outcome than you do about making his job easier. But in general I would vote my honest preference in a poll like this. (Whereas I would definitely vote strategically in a straight-plurality poll.)

    In point of fact I'm sitting this one out because I don't have a strong opinion and I prefer to free-ride on more informed opinions.

    Okay...
    Mean: 23
    Median: 24
    Mode: 25

    With such a tight range of votes (5 IBUs), I believe a runoff of any kind would be of little value. Calling this for one the value that is the average (mean and median) of the averages: 24 IBUs

    Most people cannot differentiate increments of 5 IBUs anyway, so although there is something to it in the end, essentially 22 is the 'same' as 24, and 24 is the 'same' as 26.

    Since this poll is over, I guess I can comment without breaking my rule about unduly influencing results.

    I agree that 5 IBU differences can be hard to detect. But I also firmly believe that the difference between 20 and 25 is easier to detect than, say, the difference between 60 and 65.

    I totally agree on that as well, the higher you go the muddier the waters get shall we say?
