Great video guys. Hey you used Celsius temps a couple of times and that is extremely helpful for me. I wish you could do more of that. Don’t worry about the pounds in gallons this is easier to deal with later but when you’re going through these explanations know right away what the C temps are is great. Just feedback from one of your international followers. Thank you.

@@GenusBrewing Thanks for the reply! I saw you have celcius on some spaces. Alreay thanks for those. I still think you make awesome videos and you know what you're talking about. I work in a brewery rooted in the 80's and we do very old fashioned mashing. Starting at 36, then 45, then 52, 62, 68, 73 and then mashing out at 78 (that's all celcius ofcourse :D). When i brew at home I more often than not do a one step mash at around 69 degrees celcius. I've not found many differences in either body, sweetness or foam stability. I was very excited to see your video about this topic because i know you guys know your stuff. That's why I'm also very interested in Peter's 'bluuhhh' (complicated) story to get more to the bottom of this. Cheers and please keep making awesome videos!

Had to stop the video at the graphic to write down all that good information! You didn't say much about how long the lower temperature steps should be - any thoughts would be gratefully received. I tried a ridiculously complicated step mash last year, and wasn't convinced it improved anything. Next time it'll be just 45ºC and 65ºC steps for a nice light beer.

Unless you’re in a technical career such as medicine or maybe engineering...? , no one here uses the metric system and I certain don’t want to.

Big fan of the “good eats/Alton brown” break down of brewing

Great vid, usually herms coils are in the HLT so you are recirculating your wort through the herms coil that is submerged in hot water to keep your wort at the right mash temps, that way your wort never contacts a heating element directly, and never has a risk of scorching. Not sure I've ever seen someone use a herms in the mash tun and ran hot water through the coil to heat the mash, but I guess that is what you were referring to. Different perspectives on how a herms operates I guess?

@GenusBrewing

4 жыл бұрын

Yep! I worded that super weird. We actually do run hot water through a heat exchanger in our mash to mimic the effect of a jacketed mash tun on the commercial scale, but it's definitely not a proper HERMS :p I'll make sure to clarify that when we talk about ways to step mash :)

Fellas Could you talk about and possibly demonstrate a Herrmann mash method, where the mash is split in order to increase the amount of glucose in the wort for enhance banana aroma in hefeweizen beers?

Out of curiosity, for a recirculating mash setup (grainfather/foundry/etc.), when would you start your timer for subsequent rests? When the liquid gets to the rest temp. or the grain bed gets to the rest temp? In my experience it takes a significant amount of time for both to reach equilibrium. Great video!

@GenusBrewing

4 жыл бұрын

Cheers! I usually go by grain bed temp, or split the difference between though. Going a bit longer in a protein or Sacch rest should change the beer much though.

How does step mashing affect the overall mash time for a brew? Do you add the transition time between steps to your calculation? I know this is probably a stupid quesstion, but what would happen if you simply mashed in at your lower target and slowly increased the temperature throughout the mash time? You would certainly hit all the important points in your mash steps.

should a homebrewer making a simple good tasting beer be more concerned with alpha and beta amylase? are those the ones that control how much body and flavor and sweetness you will get? so what is the rule of thumb about your waters ph? can this be controlled by using citric acid or will this possibly affect the taste too? then how long should each resting period be 1 or 1.5 hr? should we start at 140deg F for the beta for 1.5hr then move up to 150dgF for another 1.5hr for the alpha? can we first have a simmering or boil temp for the unmalted grains towards a gelatinous phase to extract as much body and flavor and then lower the temp accordingly to add the malted grain and start the mashing periods?

Do you guys use both a beta amylase rest and an alpha amylase rest to get the most out of each enzyme? If so how much time for each?

I was hoping to see a example of step mash schedules for different kinds of beers. I am uber low tech small 2.5G batches... a canning pot biab... with a Inkbird and a hot plate.... so feel free to beer nerd out!

Yoo, "I'm super good at videos." had me rolling.

I would appreciate the more in depth version of this

I leave my mash overnight to get better extraction, is that bad idea? Will that extract tanins?

so mash about 109' rest, 125' rest, 151' rest, sparge at 170'. how long are these rests and should the grains be submerged under HLT water?

I don't make sparge i use all the water I need, I don't do mash out because I make when i boil whit the hopes and I don't do protein rest because happens when i boil. If I am right please coment

So what about BIAB full volume infusion mashes. Do the techniques change or are the results different?

@GenusBrewing

4 жыл бұрын

With full volume mashes there are a couple of factors at play - one is the mash pH which will be higher in a full volume mash - so that has to be accounted for. As a general rule though, you should spend slightly longer in a full volume mash than at a 1.25qt/lb mash

I always mash to completion, LOL!

@@GenusBrewing Works for me. 10:45 am, I will have my morning drink with you guys.

So, what happens when you mash at a particular temp, like 154 and for whatever reason, you lose 5-6 degrees and you DO NOT have a way to recirculate or easily add heat? How does it affect what you get? How about the reverse? You mash in and temps drop 10 degrees, so you compensate by adding hot water and you overshoot to 158-160 but you don't catch it until 8-12 minutes mashing has occurred (nearly half of the time the bulk of mashing is effective). Is one situation worse?

@GenusBrewing

4 жыл бұрын

So at 154 B amylase degredation isn't too bad, but stir vigorously to try to get that temp down just a touch. If I way undershoot, i'll generally give it 30-45 minutes at the lower temp (143ish lets say) and then run out some wort, boil it, and add it back to try to hit a higher mash temp. At 158-160 B amylase degredation is really fast so you can expect a thicker beer. Best practice at that temperature is to stir intermittently and plan on a longer mash time.

@JoeGraves24

Yes to that Genus Brewing. Also, I have used decoction mashes to raise the temp in a cooler setup. Basically take a gallon of the mash/wort mixture out of the tun and put it in a stock pot. Bring it to 152° F and hold for 15 minutes for the sach rest. Then bring it to a boil and add it back to the tun. I’ve found that it takes a medium gravity beer from 142° to 152°. An extra bit of beta amylase rest won’t hurt much while the decoction is cooking. Just don’t boil it for too long: could make some funky/astringent flavors.

Genus Brewing right on! Do you mechanically agitate the grain bed (similar to a mash rake) while using the herms variation you describe? Also- what are your thoughts on infusing the mash with steam instead of just recirculating (near) boiling water? I imagine it would be much more energy efficient. You’d have to calculate for the thinning of the mash as the steam condenses - though I’d be willing to bet the additional water would be negligible
