Beer Stopped Fermenting Then Start Again a Few Days Later

   Then I brewed my beginning beer two weeks ago (a 1gal all-grain IPA kit from Brooklyn Brew Shop). Everything looked expert at start- got it brewed, stuck information technology in the fermenter, and got some adept fermentation a few hours after.

   Lots of kraeusen and whatnot for the first few days, then things started settling down. At this point, everything is still good.

   And then about four days subsequently, fermentation stops (again, normal), and its looking similar I'thou going to exist bottling on schedule on January 9th.

   Nonetheless, three days before the bottling date it starts fermenting again, with streams of tiny bubbles shooting up the sides of the glass carboy. It's still going strong today, now 16 days later brew day.

   Is this normal? I think it's weird that the fermentation stopped and restarted.

   Temps have been pretty consistently betwixt 65-70F. I have a hydrometer, only a one gallon batch is really besides pocket-sized to mess around with samples unless I can pour the sample back in the fermenter.

   Thoughts?

2. It could exist CO2 escaping from solution, not necessarily re-started fermentation. However, there is no need to rush information technology if you are only 16 days in. No harm in hangin' out a few more days earlier bottling.

   Don't pour any samples back into the fermenter. Look a few days. What is your final gravity target? What was the original gravity? What yeast did you use?

   I didn't take any OG measurements since I didn't have my hydrometer at that point.

   The kit says it should come up out to nearly 6.eight% ABV. Online it sounds like near people become final gravities between one.012 and 1.010 and ABV between 4.ii% and 5%.

   I'm hesitant to do a hydrometer sample since the one gallon kit is only going to make about x bottles.

   As for the yeast, I pitched what came in the kit. It didn't specify type, just it was dry out and called for the whole parcel to be pitched. Then I aerated the hell out of information technology and let information technology do its thing for the last two weeks.

   I retrieve you are well on your way to a good beer, and that fermentation is probably finished. The bubbling that you are seeing are probably from what AlCapone says. Y'all will take to surrender some of your beer to have a couple samples for your hydrometer readings to be sure that the gravity is stable. Merely you're going to want to sample your beer too, and then drinkable the samples and bask that experience. That's role of the learning fun of this hobby.

   Cheers for the advice! I'll definitely take a few hydrometer readings.

8. If you lot brand bigger batches y'all won't miss the samples equally much.

   I just did a hydrometer reading. 1.011 or so. Based on what I've seen online that's what a lot of other people are getting with this kit.

   I'll take another one in a few days and encounter what happens.

   Sample tasted good though! Massively biting, but hopefully when it'southward cold and carbonated that doesn't come through as much.

10. I have plant that samples normally come up through far more biting than the final product.

    Aye, only I don't take the space to do bigger batches. The one gallon batch took up most of my stove and counter space. Plus I'1000 moving to a small flat in fall, so space is nevertheless going to be an issue.

    I want to see if I can manage 2.5 gallon batches on an apartment stove, and then then I make virtually a example every time I brew.

12. You probably can. A pot big enough for that size batch will probable boil well on an average electric stove. Also much bigger, probably not, but ii.5 gallons is quite feasible.

    I do 2.5 gallon BIAB all grain on a kitchen stove (5 gallon brew kettle), that'due south the manner to become if you're limited on space. I get 25 to 28 beers per batch. Do you have an electrical or gas stove?

14. Fermentation doesn't just restart...either the temp/molecular vibration went up or God intervened.

    At home I have gas, but I'd be surprised if I tin can detect an flat with a gas stove. I'd adopt gas since information technology's easier to control the temp and I cook a lot, so temp control is important, just I'm non going to be picky on a poor grad student budget.

    2.5 gallon batches sound pretty doable. And if you get well-nigh a case it's fashion more cost effective too. I liked the ane gallon thing, but I'grand probably only going to score about 8 full bottles after these hydrometer samples which makes information technology more than expensive than ownership a $10 sixpack of world course beer.

    I thought that the temperature probably went upward. We kicked upwardly the heat in the firm when information technology was -20F in the mornings early this week, which coincidentally correlated with when I noticed the resumed bubbling.

    Continue in mind that you lot'll demand to offset with about 3.75 gallons of water pre-boil to compensate for boil off. When I had an electric stove, I was unable to bring three.75 gallons of water to a eddy. Make certain to borrow a 5 gallon pot and endeavor bringing iii.75 gallons of water to a boil on the electric stove before purchasing the equipment.

    If you lot're gonna do a lot of small batches similar that, get yourself a refractometer, and then use beersmith or an online calculator to decide the final gravity of your beer from the refractance measurements (you need the original gravity likewise to estimate the ABV and terminal gravity). Information technology's really easy to practise, and yous only demand a few drops of wort or beer. It may not be every bit accurate every bit a hydrometer (could be more than, though), but you will easily be able to tell when you lot've reached terminal gravity with a refractometer. I got 1 a couple years ago, and haven't used the hydrometer since.

18. Please...either a refractometer OR a hydrometer will do...added heat and a little rousing is what the physician ordered.
    Fifty-fifty for modest batches...ya gotta beverage the hydrometer sample...so nothing wasted.

    Wow, lots to think virtually.

    I'll definitely wait into the refractometer, especially if I won't be able to motion up to a 2.5gal arrangement when I motility places subsequently this yr.

    Thanks for all the tips! I can't wait to keep brewing.

20. Brand sure you read all the "boy this refractometer is a royal pain in the donkey" threads before finalizing whatever decisions.

    FarmerTed Aspirant (215) May 31, 2011 Colorado

    They're a pain in the donkey? Actually? I find the ane I have easy as hell to apply. Listen to what the OP wants: a manner to measure gravity without wasting v% of the beer in his fermenter. A refractometer is perfect for that, if you acquire how to use it.

22. 

    Beric Initiate (0) Jun 1, 2013 Massachusetts

    I'll figure things out.

    I think I'd desire to look into a 2.5gal system earlier a refractometer. I merely want to brand more beer.

23. On the original topic, I had the verbal same matter happen with the exact same beer kit. The temperature variation was only +5 degrees, and none of my other batches did anything abnormal. To the OP: Did the batch come out okay?

24. 

    Beric Initiate (0) Jun 1, 2013 Massachusetts

    Everything turned out okay! The mash is massively bitter and needs to be drunk really common cold for summit enjoyment, simply it smells similar beer and tastes like beer. I give mine a 6.5/x, so in that location'southward plenty of room for improvement.
