• Failed fermentation

    Now it happened, I might lose a batch. Or maybe not? A barley wine
    started out at 1.092. Using harvested BE-256 Belgian style yeast it had
    an unusually sluggish start. Nothing for about 30 hours and then it
    began very slowly. Judging by the dried gunk under the primary fermenter
    lid if must have kicked up a good kraeusen though.

    Three weeks later (yesterday) I transferred to secondary and the gravity
    had only dropped to 1.047. It also had a slightly sour taste but I
    transferred it anyhow. Since it then just sat there with no airlock
    activity I pitched another pack of yeast but only had US-05. Airlock
    activity came back after some shaking but it is anemic, at about one
    bubble every 5-10 seconds. 24 hours later still not much and no kraeusen.

    Is there hope? Anything more I can do? Maybe pump some air into it with
    a hose?

    If I lose this batch it would be sad but considering that this would be
    the first loss in 234 batches it's still ok I guess, statistically speaking.

    That's a good track record.

    How about raising the temperature? I mention it in case it may have slipped your
    mind.

    Sound like you already did that most would do when you get a stuck fermentation.
    One other thing you might try is yeast energizer to kick start it back into action.

    Yeah, I try to be really careful when it comes to sanitation. I think
    that has paid off over the years.

    Tried that. The only thing that got it going a little bit was vigorous
    shaking of the secondary fermenter (a glorified office cooler water
    bottle). Even that only aroused very tepid airlock activity.

    Interesting, thanks. I'll have to see what yeast energizer is. What
    really concerned me was that the pitching of a fresh packet of US-05 did absolutely nothing. Right now this fermenter just sits there with the
    airlock showing a very slight and constant pressure. In a week I'll dip
    a straw in there and sample a little for a taste test. If ok I'll let it
    sit for another couple of months. If it's sour or funky I'll dump it
    because it will likely have become unfermentable.

    Luckily the Belgian Quadrupel which I fermented about three months ago
    with the same BE-256 yeast strain came out great as usual. I bottled
    that on Monday, along with an IPA.

    Thanks. Though I haven't had much luck with groups.io. The access is cumbersome. Usenet is so much easier.

    The saga had a happy end. This week I bottled the Barley Wine and
    another beer. Before investing any more time in it in case it's gone, I sampled some from the secondary fermenter with a sanitized straw, into a beker. Tasted ok. Not super-special but good enough to bottle. Then I
    brought it outside for bottling the next day. This involved a fair
    amount of shaking and a temporary loosening of the airlock (so the
    StarSan in the airlock won't get sucked into the brew during the
    hand-truck roll).

    Not sure if it was the shaking or the fresh air getting into the
    fermenter but the next morning I saw it bubbling away vigorously and
    forming a kraeusen. So I bottled the Pale Ale first to give the Barley
    Wine until early afternoon. By then it was down to 5-10 airlock bubbles
    per minute. Racking into the bottling bucket I sampled again as usual -> shazam! Best Barley Wine I ever had, with a nice smooth Brandy taste.

    Best of all, since my wife doesn't like Barley Wine and none of my
    friend do, it's all mine 8-)
