Direct heat, recirculated no sparge Hochkurz infusion.

Nowadays I do 20-30 minutes at 62c, 30 minutes at 72c, and 10 minutes at 76c.

Gracias.
I won't have the capability of adding another inlet & pump to my cooler mash tun this weekend so I'll plan on stepping via underlet infusions.
Is there any issue with losing effectivity of SMB in the infusion water if it's at temps near boiling?

No decoctions for me anymore.

Sulfur dioxide will volatilize faster at boiling temps (you'll smell it and if your eyes are right over the liquid, you'll feel it too). Don't let it sit too long, but give it enough time to completely dissolve and uniformly mix. A couple off minutes and one light stir is sufficient on my system.

That's interesting, I thought everyone was doing 45-60 at 62 and 60 at 72? When I was doing shorter times like yours my fermentability wasn't as good.

I adjusted my circulation a bit and also dropped my mash pH to 5.2. No problems with attenuation, body, or foam :tu

Nice, I suppose you also have dropped your smb dose down as well with a shorter mash schedule?

50 mg/l. I'm also doing a 60 minute boil with 10% total evaporation.

Those who stopped doing decoctions, what do you think about doppelbocks, would they get the same character with the step mash? I wonder if a separate pot for the decoction would work.

Another knife in the back of decoctions for the record, (I love the idea and traditional feel of doing them and have defended them vigorously in the past).

The recent Zymurgy posted the winning Light lager, Pilsner, Dark Lager, Light Hybrid and Bock NHC winners and they are all SINGLE INFUSION recipes!?? The Euro Amber Vienna had a single decoction.

Having won homebrew comps and having had ridiculous score sheets as well, I understand how subjective it can be, but I am surprised as well, thoughts?
