    Mine are lucky if they get one!

    Is this the right time to have a discussion about accuracy and precision? :fallingoffchair:

    I'm pretty sure that after having a RR Saison and one of Troy's RIS's, two decimal points is the best you're gonna get.

    I am 98.593806503%+-1% sure having more precision is always better.

    How are you measuring to 2 points? I wouldn't have thought any home brew methods are that precise.

    But still, how? You might be accurate, but I doubt it's that precise.

    If using a hydrometer, only a 2 point difference (i.e. one line) on either OG or FG can throw your ABV by 0.25%. Double that error if you're wrong on both OG and FG.

    Even if you could get it to a 1 point difference, you're still talking 0.125% error.

    I've made up a look up table based on this calculator: http://pint.com.au/calculators/alcohol/

    A wine making friend testing a few of my beers for shits and giggles with an ebulliometer and found it was pretty spot on (within 0.1% generally).

    Spreadsheet attached.

    Of course the 0.25% error varies with OG and FG (it's not linear), but that's for an OG of 1050 and an FG of 1010.

    Brewmate recipe sheet never lies.....I mean, if I can't trust it in areas such as these, what's next? Sheet says wheat, I have to take it at it's word.

    pretty sure most of my beers are exact percentage, +/- 1/10 * 10^1 percent, at least :p

    Had Liams Peppercorn Saison yesterday, great layer of yeast flavours, added to by subtle pepper flavours. I didn't perceive it as dry as I normally associate Saisons to be, perhaps there was a little buttery slick there, which took that perception away.
    Lacing the glass all the way down to the final drop, I enjoyed it, thanks mate :)

    Sweet, one of these scheduled for tomorrow...+/- a day. Not sure how precise I can get it. Actually, I 'member when I was running a Behringer Steel saw back in the day, they put me on that cos of my precision. Mind you, t'weren't beer involved.

    Choc wheat is an acceptable substitution to wheat.

    Cheers Martin! It finished at 1.002

    I hopped it late with about 4.5g/L of mandarina bavaria, maybe that added some perceived sweetness / oiliness?

    But how do we know it didn't finish at 1000 or 1004?

    That could very well be it, and I was thinking of it last night, after posting, perhaps the alcohol also added to that perception!
    Great beer none the less :)
