Temperature and yeasts
« on: September 29, 2010, 07:42:15 PM »
I usually have a nice window this time of year to brew with the temps falling in Philly.  The problem is my basement is not cooperating this year.  It has been constantly at 76 degrees.  I have plans to do a Strong ale and an Amber, similar to Red Seal.  Do I   1. Put my fementer outside after the sun goes down and bring it in during the day? or 2. Is there a yeast that works better at hight temps?

3. Set up some kind of temperature control. All you need is a bucket/cooler, some water, and optionally ice/towel/fan.

Short answer is that 76 is too high for any of the yeasts I am aware of.

Some other factors to consider, is that the sunlight is not good for your beer (skunky smells), also, I have found that ramping the temperature up and down on yeast is worse than fermenting warm.

So I would find a spot that is fairly constant temperature, place the carboy into a pool of water, stick a t-shirt over the carboy(to wick up the water out of the pool or tub of water) and put a fan on the carboy.... as long as it is not too humid, you will drop 2 to 4 degrees off of your temps.

Another possibility I have seen is to take a large garbage can, fill it with water, and put the carboy into the water (keep the beer line in the carboy above the water line so that  the carboy will not float.)  And then put frozen gallon jugs water into the water.  The blocks of ice will melt at a fairly constant rate and with a little experimentation, you can add jugs at a constant rate to keep the temps down.

Good luck!!

Is there a cooler space in the basement, say on the floor near an exterior wall?  You might find something that would carry you through 'till the temps drop.  Otherwise make wine - it likes to ferment at that temp.
Beer...Now there's a temporary solution!

You gotta cool the beer down as you know. It's the nemesis of homebrewers. Screw placing it outside and temp swings. Even in a box with frozen bottles will work. Throw a couple blankets over the box even better. No box? Wrap the frozen bottles against the fermenter with towels and switch them out every 12-24 hours.

Invest in indoor/outdoor thermometer from Lowes or Home Depot to monitor temps.

I agree with the posters in that 76 is too high to ferment most ales.  There's really no other choice but to gain control of the fermentation with either a swamp cooler or a fermentation control chamber of some sort.  This is a common issue that homebrewers struggle with and unfortunately there's not much one can do about it other than tackle it. I know it's probably not the answer you were looking for but it's one to be dealt with.

I usually pick my yeast based on the temperatures in my house. I usually go through the list of yeasts from the northern brewer website, my local brew shop, or the wyeast site and pick according to the temperature tolerance and the characteristics I'm going for. It's hard to get too warm for Wyeast 3724, Belgian Saison.

I do the opposite.  I base yeast choice on the flavor profile I want in the beer, then adjust the fermentation environment accordingly.

That's what I do too, but if you can't control your fermentation temps then picking a yeast based on the prevailing conditions makes sense.

Maybe so, but if I want to make an APA, I don't think I want to use a saison yeast just because it works at high temps.

Don't you mean "if you WON'T control your temps"?  Almost anyone should be able to control their temps if they want to.

Using Belgian strains is a tactic but will only get a brewer so far. Just because they can handle higher temps (boy will they!) doesn't always mean you'll get traditional and great results from them. Those yeasts are usually started out cool- in the 60's, and allowed to slowly rise several degrees by some brewers. So going Belgian isn't a magic bullet.

As stated before it is actually fairly easy and inexpensive to bring the temps down.

 Agreed.
  Anybody can sit a fermenting vessel in some water and cover it with a wet cloth. An old tee-shirt, curtains, your underwear. No excuse.

No, I mean can't although I might add the word "sufficiently".  :) If it's 85F in your house a swamp cooler is only going to get you so far.  And seriously, how often do we see people on this board recommend kolsch or California lager yeasts for someone wants to make a German lager but can't reliably get their temps down low enough?  That is the same thing.  I know there are lots of ways to bring temps down, but they're not all realistic for everyone, whether because of money, space, SWMBO, or other considerations.

And to your point Denny, if you want to make an APA you might want to wait until the temp comes down and make saisons in the summer.  Seasonal brewing was the standard for centuries, pretty sure we all know that. :)

I understand your point about seasonal brewing, but dammit, I want what I want when I want it!  :)   Putting my fermenter in a tub of water in an interior closet and adding ice packs, I can maintain 65-70 with an ambient of 85-90.
