    Hi,

    First home brew in about 15 years! I've left my brew in the fermentation bucket for 3 weeks and will probably keg it after 4. I've been keeping the temperature as close as I can to 19°C in a brewing cooler. Once I keg it do I need to maintain this temperature or cooler? Room temperature here varies between 25°C at night and 32°C during the day.

    Thanks for a refresher in the metric system :slight_smile:...if fermented at 66*F with ambient temps of 77*F low and 90*F high, it still depends WHAT you are brewing, but generally speaking if kegging, you want to drop the temp to normal refrig temps to force carbonate (~ 35*F or 2*C)...many variations if using odd-ball yeasts, dry-hopping, or you like fusel alcohols. :slight_smile:

    Question for you: What's going on between week 3 and 4? Cheers

    I don't think anything much is happening besides clearing if the beer during this period. But I really don't know. What is actually happening?

    This is the recipe i am brewing:

    Monks in a barrel abbey ale
    4lbs caramunich
    3lbs premium 2 row
    3lbs Vienna
    0.5lbs aromatic
    0.06lbs chocolate
    1lbs light Belgian candi sugar
    0.5oz galena
    0.5oz fuggles

    I can't remember the yeast at the moment and not by my pc to check it out but it was a dry pack of sa4 or something like that.

    like any food, beer will stay fresh longer if kept cold. homebrew is a bit unique in the world of kegged beer but it is still beer, and thus cold temps will help to keep the beer fresh.

    warm temps increase the effects of oxygenation and decrease the time required to have an effect. warm beer stales faster than cold beer.

    warm liquid will not hold as much CO2 gas as cold liquid. so if you want your carbonation to be anywhere near ideal you must force carb at 38F. i'll let you convert. once you have obtained the proper carbonation, you can store the beer at a warmer temp, but you must dispense at 38F, and attach your regulator to the cold keg. you can not carbonate or dispense warm beer, not even cool beer. it must be cold, preferably as close to 38F as possible.

    cold temperatures allow the beer to lager. all beer, even ales, benefit from some lagering. with a lager beer the lagering is clearly mandatory but an IPA or any ale will be noticeably better if allowed to "ripen" at a cold temp.

    long term aging may require cellar temps, but that is a different subject. and even then cellar temps are a lot less than room temps.

    basically, unless you can't, keep homebrew keg beer cold always. not always possible and not a crime if you have to store a keg in the basement or cold garage until time to drink.

    Cheers.

    Biilandsuz,

    Thanks for the explanation. 38F is just over 3C which means I am going to have a small problem. I live in the Caribbean and the coldest it has ever been here to my memory is 21C or 70F and that was in a valley in the mountains very early in the morning :slight_smile: Even if we had basements or cellars the temperatures wouldn't be anywhere near that low. :slight_smile:

    I guess I need to go find a fridge that can fit my corny kegs! I don't think I can keep my brew cooler at that temperature for any length of time.

    I take it that GreenKrusty101 was alluding to the yeast still working during this time to help clear the beer. Is this the attenuation or conditioning phase?

    Out of curiosity, how were you planning on serving your beer if you do not have a fridge or kegerator for your keg?

    When GK101 talked about dropping the temperature, he was talking about after attenuation was finished. I don't think he was alluding to the yeast still working.

    get yourself a small chest freezer to serve as your beer fridge…it pays dividends

    this is good advice, but you do need a temperature controller too. whatever they have in Trinidad that is equivalent of Craigslist, that is where you want to be looking.

    Cheers.

    Does temperature matter once its kegged? Yes it does! Unless you want to drink warm, room temperature beer and pour a big glass of foam IF you can get it carbonated.

    Carbonate for two weeks and serve at 2-5C.

    Was going to put it in my brew cooler with ice.

    yep, I've started looking for one and at various videos converting them into keezers.

    Any recommendation for a temperature controller? I can buy off Amazon or eBay or anywhere else that accepts international credit cards or offers PayPal.

    the standard dial control no frills Johnson A19 controller is industry standard. it is used all over to control walk in coolers, chillers and anything you can think of. reliable, simple, wont ever break. probably not ever. cheap too. just set the dial, position the probe and your done. you do need to fiddle with the probe to get it just in the right location, but that's it.

    the Ranco ETC and the Johnson A 419 are digital and offer a bit more control.

    I am using all of them in various projects. any of these are a very good choice.
    Cheers.

    Thanks again. I've actually found a small chest freezer that has dual functionality in that I can switch between being a fridge or freezer depending on what I want, so I will probably get this today so that I can do my kegging this weekend. If I find it too difficult to control the temperature using the built in thermostat I'll try the temperature controller.
