Kai vanished due to work and family.

Are you suggesting that there are people who have lives beyond the forum?

I try...  Sadly the forum is as close to brewing as I have been in months.  Perhaps tomorrow.  I have the day off.

I know the feeling.  Yesterday was the first time in 2 months that I'd brewed at all and the first time in 6 months that I brewed for myself and enjoyment.  No experiments, no testing of equipment, ingredients, or process...just plain old school brewing for the fun of it.

Nice.  If I get lucky I'll split some wort tomorrow into a tripel and a saison.

I can't help myself -  I boil the crap out of it outside in the cold for an hour because all that rising steam and jet-engine noise makes me feels rugged, dangerous and macho.

For reals.

Just finished brewing a M Dunkel and I revised my boiling procedures in response to this thread.

I reduced my boiloff percentage to under 10% by covering the kettle to almost 100%. I had been covering the kettle by about 1/2 to 2/3, but my boil loss percentage was on the order of 1 gal/hr. That was too much. I knew I had to implement change.

So with the lid barely cracked, I quickly found that I needed to reduce the power. I had been boiling with a mild rolling action with the power modulator set at 45%. I had to turn the setting down to 20% to get the same rolling with the cover on. So, there is a big energy savings with the cover on. I did find that its important to keep your face away from the kettle when checking the boil! Steam is hot!!!

I did boil the last 15 min uncovered to help assure that DMS was boiled out and to meet my 10% volume loss goal. I'll bump that down to 8% in the future if this approach seems to work well.

These were changes that I needed to do. We'll see if they improve or degrade the beer.

Martin,
did you implement any other low oxygen procedures in this brew day besides lighter boil?  Just curious.

Yeah, I use SMB and BTB in my brewing.

Cheers Martin! I think you will be really happy with the lower thermal load in conjunction with your normal practices.

I did my boil mostly covered yesterday as well.  I had to have the burner down so low the flame went out  couple times, but it was a little windy too.

Pre-boiling pretty much offset any propane savings though.  And added hugely to the length of the brew day.

Anyway, I implemented what I could for reducing DO.  We'll see how the beer comes out.

I had miserable conversion with the underlet undisturbed mash.  Maybe I need to crush finer...

When you say undisturbed mash, you mean you didn't stir at all?
