    -> Poll #1 <- determined that the ABV target will be 7.0%.

    This poll will determine the target Final Gravity, as well as the target Original gravity.

    I suggest thinking about residual sweetness, body, and mouthfeel. Even though there is no (group) grain bill context yet, there may be one in your head.

    Here is the formula I used to determine the potential FG/OG pairs.
    ABV = 131.25 x (OG - FG)
    There are formulae that would give slightly different answers. This is the one I used.

    This poll will be open for 48 hours.

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

    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.

    The Averagely Perfect Dubbel Recipe so far...

    Target ABV: 7.0%
    OG: TBD (this poll)
    FG: TBD (this poll)

    Going to need to hear other people's thoughts on this one. I'm leaning toward a low FG because this style is supposed to be dry and drinkable ("digestible" or whatever), but not all the way at the bottom of the spectrum. So I'm thinking like 1.012, but I am eager to hear from people who have brewed this before.

    Lower because we will be using candi syrup.

    This is a good point. When I think about "re"-creating trappist recipes, which I do frequently, I tend to start by targeting og and treat fg/abv as outputs as opposed to process drivers. The attentuations in the style is definitely high, but so too is the range. If you think about abv/fg too early in the process the final numbers end up dictating the process and grain bill, and not desired characteristics of the beer, not something Belgians like to do!!!

    I picked 1.015 just because the last dubbel that I brewed that took a blue ribbon finished at that FG.

    Vikeman, are we going to vote on making our own candi syrup? or is it assumed that we have to? ;-)

    I have settled on making my own BPA.

    This dubble will be a dubble. I have D-45 from another brew where I decided to cut back some sugars added, so I will be looking to use that.

    All said, I still went with 1.012.... this I prefer slightly higher FGs, even if this is my "year of low ABV brews"....

    I voted on the low end of FG also. I think a style like this really benefits from not getting too crazy with the specialty malts, but instead relying a healthy dose of dark Belgian candi syrup to get the color and raisiny/dark fruit characteristics that the style is known for.

    Exactly my thought, a healthy dose of dark candi syrup and a light hand with specialty malts will lead to a low FG, lower than the 1.012 most are voting for.

    How did you vote? By my calculation 1.012 would amount to 81.5% apparent attenuation, which seems about right to me, but I'm persuadable.

    I voted for 1.009, because this is the leading low FG vote at this time. If I would have voted immediately without considering other votes I would have voted 1.010.

    I did not run a calculation before voting, but from years of homebrewing I can say my calculated FGs almost always run higher than my real FGs, especially if a beer is using a normal mash temp and moderate specialty malt additions.
