    Hey all, I'm pretty new to homebrewing & am in need of some help/advice. I was recently brewing my second batch of beer - "Saison de Lawnmower" from Midwest brewing. Everything seemed to be going great, got the beer in the primary, was getting bubbles within a few days. Then, a Snowpocalypse hit Little Rock, AR & knocked out my power for 5 days. As a result, my beer was subjected to pretty low temperatures (~40 degrees) and stopped bubbling. After my power was restored, I slowly let the beer come back up to fermenting temperatures but have not had any bubbling (even raised the thermostat to see if it would help). My questions are: is this batch a bust? am I not seeing bubbles because it's finished fermenting? is there anything I can do to save it?

    The obvious thing to do would be to take a hydrometer reading & see if any fermentation had taken place. Unfortunately, I forgot to do that before placing it in the primary, then decided not to worry about it once I had remembered. Now, I'm kicking myself in retrospect.

    If it helps, here's a more detailed timeline:
    12/21 - Batch brewed & placed in primary fermenter
    12/25 - Power goes out
    12/26 - Temperature in the house drops to 40 deg.
    12/31 - Power restored
    1/1 - Thermometer on fermenter reads 60 deg.
    1/3 - Thermometer on fermenter reads 70 deg.

    Basic Brewing Rule #1: RDWHAHB
    Basic Brewing Rule #2: lack of bubbles don't mean doodly.

    ---
    Now that the wort has warmed up...gently swirl / stir it to rouse / re-suspend the yeast.
    No reason to think fermentation won't fire up again.
    Also...there's no reason not to check the gravity b/c it's the only reliable way to know whether fermentation is over.

    ---
    Next time the power goes out mid-fermentation...place the fermenter on a folded blanket and wrap another one around it to conserve heat.

    The bubbles in my airlock routinely stop bubbling at 3-4 days...what is your hydrometer now? Oh yea another LR person hear snowmagedan this year was epic.

    Even if you didn't have a pre fermentation reading a "post" readingis always helpful.

    You should be fine, as long as too much air didn't get in.
    Most likely fermentation is going on, just the primary was over and things are happenning much more slowly.
    Absolute worst case scenario, pitch a new pack of yeast. Not a big deal if you can't get to it for another couple days.

    You make a good point about air. I'm not sure about the timeframe, but if you cold crash a beer it will suck fluid from the airlock into the fermenter. Is two days of cold air enough? I don't know, but I'd check.

    OP: check your airlock/blowoff solution and make sure you're still air-tight.

    Thanks for the comments everyone.

    The water level in the airlock is still the same - so I assume nothing sucked back into the fermenter. I'm going to take a hydrometer reading in the morning, but will that tell me anything without taking an initial reading? Maybe I'm not reading it correctly.

    Glad to hear that the lack of bubbles don't mean something bad is happening - though, a little bubbling would certainly put me at ease.

    Another question, if this batch fermented ok, will the 4 day chill have adverse effects on the beer's flavor?

    If by intial reading you mean Original Gravity (OG, before fermentation), that would be useful, along with Final Gravity, for determining ABV. But even if you did not take an OG reading, you can still take gravity readings to help determine whether or not your beer is finished. Take a reading and take another one 2-3 days later. If they are the same and are roughly where you would have expected, fermentation is done.

    Did your recipe say what the expected OG, FG, and/or ABV should be?

    What does it say?

    Ok, so I'm trying to get this hydrometer reading. I'm using a plastic bucket as my fermenter. Can I just pull off the lid & drop the sanitized hydrometer in? Surely there's a better way to do this?

    your hydrometer came with a beaker. the same thing you store it in, that's the beaker. sanitize your racking cane or a length of tubing, put your thumb on the end and use it like a wine thief. fill the beaker until the hydrometer raises and take your reading.

    then dump the beer. don't be a cheap ass and put it back in the bucket. or taste your beer if you like.
    Cheers.

    SG: 1.055-1.059
    FG: 1.012-1.016

    Is this a reading of 1.002?

    Okay, So you're looking for a reading in that range.

    No picture here. To show a pic here, you need to put it on a server somewhere, then link to it.

    That looks like 1.004-ish. You want to read it at the bottom of the meniscus. That's lower than your recipe instructions expected, but Saison yeast strains tend to be very attenuative. Do you know what yeast strain you used?

    I'm not sure about the strain. I used the Wyeast Activator option (instead of the dry yeast) from Midwest.

    Should I do something to up the SG?

    As long as it doesn't freeze, your yeast doesn't die, it just gets really really lazy.

    Looks like you've hit your numbers. I've had low % beers finish out in 4 days.

    EDIT: If there is still a lot of large yeast chunks suspended in the beer then you might have a problem of dead yeast or a stuck beer, if the majority of it has fallen to the bottom you should be good to go.

    Okay. My guess would be Wyeast 3711 then. Your FG could go even lower. Hard to say for sure.

    Nope. Just check gravity again in 2-3 days.

    There was quite a bit on the top but I think most had settled. Hard to see what's going on with the plastic bucket.
    VikeMan, thanks for all the help. I'll post a new reading in a couple of days.
