Can another 50l BM owner do a fill test of their rods? I found 5l more, not 1l more as the 20l owners are noting.
Florian said:depending on how high above sea level you are you should still get up to 101 at least.
if you only reach 98-99 then something doesn't seem to be right.
Mr. No-Tip said:Not sure if I understand the 'should' in your post.
The system should be able to hit 101? It can, I just don't set it that high.
I should put it that high? Boil seems pretty decent at 99, that's why I stopped bothered going higher, and never had any DMS issues, so figured it was vigourous enough. We're at 571m and that is supposedly boiling point: http://www.engineeringtoolbox.com/boiling-points-water-altitude-d_1344.html
I might try a 101 next time and see how it goes. (and lose the boiloff numbers I figured out today!)
Sound good, mate, why haven't we seen you at Canberra Brewers?Rurik said:I live in Canberra & brew on a BM. I do all my boils at 98 with no problems, when I fist got the BM I was worried about it not getting to 100 but then I ended up at the same website you posted. As to the DMS thing I dont think you need to worry about it at the BM scale as the boil produces enough mechanical agitation of the wort to drive it off. Also there was a great fact sheet from the IDB (that I now cannot find) that suggested the most important part of the boil (in relation to DMS) was the reduciton of the wort, it suggested that if some sort of mechanical agitation was used (say pumping the wort and returning it to the kettle through a spray ball) boil temps could be lowered to 80 Deg C*.
* As I cannot find the aritcel on this I will not quote it as gospel. Take it with a grain of salt I could be remembering it wrong.
Not sure wether DMS is a problem at this scale or not (there are different views on this at either end), but vapour does condense and drip back into the wort. Ralf at Speidel has indicated that some sort of an attachment that fits between the BM and the copper hood to catch the condensation and allow it to be diverted elsewhere is an interesting idea, but not economically viable.Pratty1 said:just a question on DMS - do you think Speidel would sell or have for sale copper hoods for the 20 & 50lt models if DMS was actually a problem at this scale?
I ask that becuase with the shape of those BM hoods, the evaporation would have to be dripping back into the wort, unless the shape creates otherwise.

I have a 50 and reckon I am way overdue to do this.Mr. No-Tip said:Can another 50l BM owner do a fill test of their rods? I found 5l more, not 1l more as the 20l owners are noting.
What I did for my system is use a piece of FG hose with teeth cut out of it then wrapped my hood with it...Brew Matt said:Not sure wether DMS is a problem at this scale or not (there are different views on this at either end), but vapour does condense and drip back into the wort.

My idea was to have some sort of tray/catchment fitting that goes around the circumference of the BM rim, and diverts the water travelling back down from the copper dome, and allows this to drained via a small outlet (then caught in a cup etc from there).
If anyone has the ability to manufacturer one of these inexpensively, I am happy to share my idea. Perhaps this fitting would replace the rubber piece that currently sits between the BM and the hood? Could be made from injection moulded silicone or plastic (ss or copper would be good, but I expect quite expensive and difficult to do).
Probably more detail than what a home brewer needs to worry about, but if it makes even a very small difference,.....
Bit of both but the emphasis on circulation. When I used a very good crush (not floury) the wort seemed to clear quicker:greg simons said:These things do look like the ducks guts. Lots has changed since I was last around here.
I am interested in the wort clarity, are people using good milling practices or is it the way the wort is recirculated through the grain almost like a continual sparge that gets it so clean. Or a bit of both.
I don't know about the head thing, but I wonder if the dilution point could make a difference? Post ferm dilution is very popular with macrobrews. I tried it once when I shot over G on a BIAB, but it's not something I'd aim for.verysupple said:Apparently for mid gravity and above beers you do a concentrated boil and then dilute.
Never get tired of that. Clear every single batch!DeGarre said:Bit of both but the emphasis on circulation. When I used a very good crush (not floury) the wort seemed to clear quicker:
