Tettnang Tiger Lager extract recipe

[rpt]

Has anyone done the Tettnang Tiger Lager extract recipe from BrewUK? Did you follow the temperature profile in the instructions (24 hours at 20C, 5 days at 12C, 2 weeks at 2C)? Or did you alter it for any reason?

That sounds about right , i would stick to that if i was you .

 

[rpt]

Thanks pittsy. I was just worried that if fermentation doesn't finish at 12C that at 2C it will be too cold to continue. I know my bread will continue to rise in the fridge so I guess the yeast will carry on working in beer too.

sorry i didn't read correct 12 c for 5 days , no thats wrong . it could be upto 3 weeks if only 1 yeast packet used , i wouldn't drop to 2c until hydrometer has stopped.

On another thread you said that you shouldn't transfer to a 2nd FV if fermentation has stopped as it needs to create a CO2 blanket. But the instructions for this kits says to transfer to a 2nd FV for the 2C stage. So would you just leave it in the primary FV for the whole 3 weeks (or however long)?

 

[rpt]

If it does take 3 weeks at 12C to complete fermentation and then another 2 at 2C that will be 5 weeks on the yeast. Perhaps I should rack to the second FV after 6 days as the instructions says but not lower the temperature until fermentation has finished.

Also, what about a diacetyl rest? Is that normally done when fermenting at low temperatures?

 

[pittsy]

yes i would transfer after 6 days then carry on until fermentation has complete + a few more days for rest then drop to 2c but leaving lid on at all times for co2 to remain.

 

[rpt]

After fermentation has finished should I raise the temperature for the rest ie a diacetyl rest?

 

[pittsy]

no , just leave it at least 24hrs longer (2 to 3 days normal) before dropping to 2 c

Thanks for the advice. The kits I have done always take longer to ferment out than the instructions say so I'm much happier now. I hope it's worth the effort - I'm not a lager drinker but hope it will keep SWMBO sweet.

I followed pittsy's advice and it worked really well. Now trying to repeat it but all grain - currently in the fridge at 12C.
