Mash Notes: Used for some authentic German styles. Attempt to draw decoction from the thickest portion of the mash. Profiles vary. Some traditional German mashes use a long acid rest at 40 deg C. Also some sources recommend the decoction amount be given a 15 minute saccharification rest at 158 F (70 C) before boiling it.

Keg/Bottling Temperature: 21.1 C Age for: 30.00 days
Fermentation: Ale, Single Stage Storage Temperature: 20.0 C
 
Beersmith doesn't really do decoction justice , what that means is take around 4 to 5 liters of the mash liquid with grain (thick ) then you would heat it up to 71c for a sacc rest for 15 mins then you heat it up till it's boiling and hold for at least 15 mins ( longer for dark wheats ) and then return to mash tun which will increase the overall mash temp . There are many reasons to do a decoction one being to darken the colour another is a more malty taste ( ideal for dunkle) does that help.
 
Sounds like a beauty - can you put some pic up when its done, I am tempted to make a dunkelweizen my next brew.

I notice you always use White Labs yeast - have you found this better than Wyeast? I have used Wyeast for my Hefe and for a Tsingsao clone - both times it was excellent so not tempted to try alternatives at the moment.
 
Thank you Pittsy yep that clears it up :cheers:
got three months before I go see my German friends is that long enough to get a Dunkle ready to drink

3 months !! try 3 weeks mate lol , maybe a little longer but 10 days fermenting 2 weeks in warmth (bottles) 1 day in fridge but at it's best from around 1 to 2 weeks conditioning and will only last a few months (6 ish ) if kept at cellar temps ,
 
@ matt , i've only used wyeast once and the pack didn't expand but have always had excellent results with white labs ( i make large starters and split them )

They do have slightly different strains, but I guess it all comes down to freshness. I've just had brilliant results with WLP565 (Saison) purchased from The Malt Miller*. The vial had a "best before" date in August, so it must have been very fresh. But must be very difficult for homebrew shops to manage a big stock of yeasts.

I tend to go for White Labs simply because Chris White seems to do a lot for the homebrew community and I like to support that (plus I can re-use the vials :) )

* 90% attenuation!!

Whoa thats quick will get some stuff ordered and copy your recipe if you dont mind .

will it be a disaster if I use some yeasts slurry from a Saison I have fermenting
its the Belle saison yeast
 
It may well be nice but you mentioned some German friends , they may be critical as it will have some lovely flavours from the yeast but I brewed a dunkle with a milder yeast (still wheat yeast ) but not right as it needs a strong banana flavour yeast like wlp 300 imo but it ;) s your beer , your choice .
 
Very interesting
Seeing as I am not time limited on this and my mashtun is big enough
if I go to 40 litrs I can spilt the ferment and do half with the saison yeast
and get the WLP 300 yeast for the othe half
 
Hey i've only just finished , It's a long mash after all. I've got an og of 1045 only 1 point lower than expected so that'll do for me.
well here they are ,
First off lactic acid to drop the ph


Grain shot all mixed up


Under letting , first mash step .


Mixing well to make sure , notice how big my paddle is lol , never realised when i ordered it how big it was.


Herms in action






The herms is just pipe in hot water




Now it's time for decoction , heat up slowly while stirring to ensure grain doesn't scorch

Then rest at 72c for 15 mins before boiling .

Now heat up slowly till boiling , no stirring needed now as it's rolling , hold here for 20 mins and it will darken nicely




First runnings , looks lovely


I mostly brew pale wheats and witbiers so this is very dark for my brews


Hops in just hitting boiling point

Boil on , time for a cuppa .


And that's it , yeast pitched job done .
 
it is so much easier , all i have is a s/s pot (around 6 litre) a bit of copper coil , some pvc tube (from local hbs) and a pump . As i use gas all i do is heat herms pot to a few degrees hotter than wort temp lets say mash is 40c and i want to get to 50c so herms is around 45c and i slowly heat it up a little while running the pump , easy , in an ideal world you want to raise temp around 1c per minute
