temperature tolerant yeast

[nine2eight]

Hi guys, I'm reading a lot about turbo yeasts etc. I guess my question is what actually do you define as a turbo yeast? For example I use a temperature tolerant Samual Willards 48 hour yeast. Would you define this as 'turbo'. Turbo is not written anywhere on the pack, however they do also sell a 24 hour Turbo pack.

the type that is premixed, the "just add water and sugar" most also makes (or tries to)high ABV 18-20+% wash.
keeping it to lower ABV of say under 17% and trying to stay with natural ingredients helps with flavor and
avoiding off taste. yes they are easy,, but like "instant" lunch their not as good.

This is an example, taken from my home forum, of temperature tolerant yeast. The test was performed by Akas, translation is mine.

Last weekend I had to make 20l of sugar mash. At the evening 18-12-2009 temperature was about -15°C. During cleaning my driveway I got an idea to try turbo in snowdrift.
Mash: 16l of water, 4kg of sugar, 1/2 Alcotec Turbo 24 Pure. Initial temperature of mash 35°C, thermal insulation 4 old jackets, bag and snow.
Next day, after 12h: mash temperature 32°C, Blg 13. I buried it again and left for next night. I was little bit worried because of temperature -25°C! But surprise. Next morning mash temperature +20°C and -2Blg. After 36h all sugar was fermented.
