Turbid mash
-
So, turbid mashing...
Have any of you ever tried it? I am really interested in this type of mashing. It's primarily used today for Lambic style beers as it leaves some starches and longer sugar chains for the wild yeast.
I am interested in trying it out on other styles as well, like a session cascadian dark recipe I have waiting in the wings, and I want to use it on all my belgian beers.
My one concer (right now) is the preboil volume. From what I have read online is the preboil volume can get pretty large. This bothers me because I only have a six gallon pot.
Anyways, I was thinking about it, and thought I would ask all you fine people!Amigo, lay them raises down. -
i've not tried it myself. i'm usually shooting to get clear wort in my brews due to the styles i've made.
it sounds really interesting though. I haven't read enough to know why the pre-boil volume would be substantially greater, given that most homebrewers only top draw the first runnings and then proceed to do a normal batch sparge.The only thing between me and a train wreck is blind luck..... - Kenny -
don't worry about the volume too much..... you need to boil for 3 to 5 hours anyway (traditionally anyhow) This will evaporate the extra volume, and burst up a bunch of starches to make them fermentable to the "cocktail" of critters in a Lambic... or keep them from messing up a regular beer without all them critters.Never attribute to malice, that which can adequately be explained by stupidity.

I used a similar method back in my early crude partial mash days.... I mashed in a pot... and pushed a strainer into the mash, and siphoned the wort out of the strainer... I also mashed kinda thick... and I had some problems with starches... really, really cloudy beer....Never attribute to malice, that which can adequately be explained by stupidity.

I guess I'm just worried about not having enough room in the six gallon pot...
I am thinking of maybe trying a couple simple infusion step mashes. I have only used my mash tun once and have only ever done single infusion mashes.

I was also thinking of adapting the turbid mash technique to better fit my system, like a step infusion turbid hybrid thing.Amigo, lay them raises down. -
You can do a modified turbid mash ...
Without the boiling water additions ... and calculate out your sparge volumes to hit just about any pre boil volume you want .... but I recommend doing the math yourself ... or you will confuse the shucks out of software ...Never attribute to malice, that which can adequately be explained by stupidity. -
Just remembered this ...... I knew a guy that also had a too small mash tun ... he did a real thick mash for 45 minutes ... drained it ... heated the first "sparge" to his mash temp ... and let it rest for another 45... the idea was to convert anything missed the first timeNever attribute to malice, that which can adequately be explained by stupidity.

If you want .... I'll run the numbers for you .... give me your:
Mash tun volume
Pounds of grain
temp you wish to mash at
desired pre boil volume
I can fairly quickly come up with a mash/sparge scheduleNever attribute to malice, that which can adequately be explained by stupidity. -
Biggest issue of a "real" turbid mash are all the starches ... if you do it right your wort will almost look like milk ... if you aren't doing a lambic that stuff won't ferment and your beer will have the body of syrup ....
That's a good thing if you want to make a very low gravity Belgian table beer ... but might get out of hand for anything bigger ... I believe that this is the reason they started using so much added sugars ... in an attempt to dry out an otherwise thick chewy beerNever attribute to malice, that which can adequately be explained by stupidity. -
Yeah. I have been thinking more and more about this. I think I am going to save the turbid mash for a traditional Lambic/ wild ale or for my session beers.
I think for now I am going to start practicing with step mashes. I feel like step mashes compared to the single infusion mash gives me a little more control over things like body and fermentability. I am a semi-control freak afterall.
Also, after reading farmhouse ales over the last few days, it seems these step infusion mashes are traditional for saison a and biere de garde.
With that being said, I have recalculated the mash rests for my next five brews using the calculation
Wa = (T2 - T1)(0.2G + Wm)/(Tw - T2)
Wa = The amount of infusion water to add
Wm = The total amount of water in the mash
T1 = The initial mash temperature
T2 = The target mash temperature
Tw = the actual temperature of the infusion water
G = The amount of grain in the mash
For the water additions at each rest. I have no idea how accurate this will be, but ill have to wait until it is actually put into practice.
I think once I get step infusions down and working with different consistencies if water/grain I will move on up to the turbid-monster, as with my current mash tun I have done exactly 1 batch, a single infusion at 1.25 qt/lb.Amigo, lay them raises down. -

pretty sure that's the same calculation i used to use. worked great for me.
Sweet! Thanks for letting me know. Why did you stop using it?Amigo, lay them raises down. -

I appreciate the input and offer to do all my calculations! I don't mind doing the math, and actually prefer doing it, as I said, I am a bit of a control freak, haha
And I like to know every detail and nuance to my system.
I can understand that! Thats why I don't trust software to do it for me ......Never attribute to malice, that which can adequately be explained by stupidity. -

i got lazy and stopped doing step mashes. :)The pinnacle of lame and awesome in one singular moment. -Lake -
Far as step mash calculations go.... I have always used the following:
Vs =
(((4M/P)+0.19)P + Vt) (Tf - Tm)
------------------------------
(Tb - Tf)
Vs = volume of boiling water to add to mash to raise temperature to desired rest.
M = thermal mass of Tun (0.20 works well for me)
P = pounds of grain
Vt = initial mash volume (pounds of grain * 0.08 + strike water volume in gallons)
Tf = Temp. of desired new rest
Tm = initial temp. of mash
Tb = temp. of infusion, typically 212 (boiling)
