Default Trappist Yeast too cold?

Hi,

I'm on my fourth batch, I'm brewing a Belgian Ale kit that I got from morebeer in Riverside, CA.

For my yeast, I'm using White Labs - Trappist Ale Yeast (WLP500). So when I pitched my room was ridiculously hot (I have no AC, unfortunately, so I'm miserable too and I also work out in the room, so it drives the temp higher). So when I pitched the yeast yesterday, I was at 70 degrees, however during the night my temperature rose to about 76-80 degrees on my carboy.

I know Belgian yeast are somewhat more adaptable to warmer temperatures but I thought my temp was too high (I don't want a ridiculous amount of bubble gum/banana flavors in my beer). So in response, I pulled out an old plastic container, put the carboy in there, filled it with ice water, then put a wet t-shirt on it, then used a fan to create a swamp-cooling effect.

Right now, my temperature is as at 64-68 degrees on my carboy, there is currently no yeast activity. What do you think? Is it too cold for this yeast strain? or should I let them do their thing in the current temp?

Thanks for helping a newbie guys!

Belgian yeasts are finicky. It's not uncommon for them to quit early when chilled. 76-80 is also not uncommon. Let it warm to low 70's and see if they pick it back up.

And for next time, pitch cold, like low 60's and keep the ambient cool so they peak in the low 70's.

So what happens if they quit early? Does that mean I have to get another thing of yeast from the store?

Have you pulled a hydrometer sample? At those temps it's possible it's already done. Unlikely, but possible.

Try warming it before repitching. It's possible they'll wake back up. If that doesn't work, try scraping some yeast off the top, pitch it into a 1-2L starter, and repitch that actively fermenting yeast (at ~12 hours or so) back into the main batch.

While labs gives 65°-72° to be the optimum range for that strain, so I would think the temp is fine. Did you make a starter? I believe that strain can be slow to start without one.

Its been 24 hours since I pitched, no activity (yet). I was going to do a yeast starter but the place I was at was out of the beakers and they kinda told me I didn't need one with the kind of brew I was doing. So I just took their word, brewed and pitched out of the bottle.

My OG reading was at 1.055 btw.

That would explain the slow start. I'm sure it will be fine once it takes off, but you did underpitch by quite a bit if it was a 5 gallon batch. Check out yeastcalc.com and you'll see what I'm talking about. Unless you're making small batches, a starter should be SOP when using liquid yeast.

You think it might be better if I pitched another thing of trappist yeast in there if it was under-pitched or just wait it out?

It has only been 24 hours? Give it some more time. There are many many many threads on here about fermentation taking up to 3 days to start if you under pitched.

If you've got another vial handy or can get one fairly easily, you may want to. Other than being out $7-$8 it can only help.
