Choosing Winter Yeasts

I ferment in my basement which provides me with a minimally fluctuating temperature. Depending on the time of year this is good with a consistent 62-65 spring, 64-68 summer, 62-65 fall... but 55-64 winter (unless its been snowing for a while). My stick on "fermometer" says that 58-62 (pretty much where I hover at in the winter) is right between both lager and ale yeasts. My question is if there is a yeast out there "perfect" for these temps and ok if it happens to drop a bit lower? I have used S-05 which had some trouble and just pitched a WYEAST 1098 smack pack on saturday.

I would like to invest into a little bit of temp control but I really just can't right now.

On a side note but on topic, does anyone have a link to a good yeast spec site or yeast database site?

I have never personally used it, but Cry Havoc can be used at both ale and lager temps, that is about all i know about it

Wyeast 1728 Scottish Ale! It's a work horse. High ABV tolerance, good flocculation, and a wide temp range: 55-75F. I have personally used it down to about 60F with no problems, so I would say it's a good bet. It's fairly neutral too, so you can use it for a wide variety of styles.

A Kolsch or a Cal Common yeast would work good at those lower temps, too.

im in similar situation so i asked around a bit and for now i will use us-05 for December-March i would use california lager strain

55-60 is perfect for kolsch http://www.wyeastlab.com/hb_yeaststrain_detail.cfm?ID=144

Thank you all!!

Some of these yeasts are exactly what I'm looking for. I think I will pick one or two and finally start yeast washing and propogating.

Pacman yeast (Wyeast) is great in that temperature range.

Notty should be in range too down to 54

California Lager (the Anchor Steam strain), is a lager strain that likes the high 50's. Kolsch yeast would be another great option.

California Ale yeast (Chico) can do 58*, but only if the temps are stable. Drop much colder than that, and they quit working.
