+1. Sounds like a bucket list trip to me. Hope there's a cancellation so you can get into Oktoberfest. Definitely love to see some pics.

The cancellation was for Weihenstephaners tour, shortly before Oktoberfest begins. We fly out on Thursday. Oktoberfest starts on Saturday. We were there once, that was enough for us.

This trip has been some old favorites, some new around Bamberg, and a lot of new places in Oberbayern.

We used to live in Germany. We get back often. Last Nov-Dec we were here for 3 weeks. The weather was crap, but the Christmas markets were wonderful. Now the weather is outstanding, and there are warm weather activities to take part of.

Ok, gotcha. Regardless, sounds pretty amazing!

Does anyone have any large scale blind triangle tests planned?

I do..but don't ask me when!  Actually, I want to try to get samples for the EB IGORs and get at least 4 trials besides my own.

Same here. It'll get done @ some point, hopefully soon.

For what it's worth, I tapped a Saison yesterday which was chilled with a new stainless chiller, and it does not have any sulphur issues (no SMB in this batch though).

Why would you expect it to have sulfur issues?

Why would you expect it to have sulfur issues?

I didn't, but others have raised it as a concern when removing all copper from a system. 

I also read the GBF regularly, and some people there have had issues with sulfur, though it is mostly (or maybe only) in the context of brewing ales with the lodo techniques (no copper, SMB, etc.).

So is there such thing as a Stainless CFC?

Denny, Martin posted a few times on how contact with copper (ie, an IC) reduces excess sulfur levels in beer. A couple months back, homoeccentricus read the GBF paper and bought a SS chiller - he reported high levels of sulfur in his beers after using it. Gonna keep using my copper IC.

Yes, but isn't the higher sulfur levels with respect to lagers mostly?  Including homoeccentricus who (IIRC) was reporting on a lager that he had brewed. I could be wrong here, though.

I'm sure more so with lagers, no doubt. And I know that Narcout was talking about a saison. I was just answering to Denny's question about copper and sulfur. I'm gonna stick with my copper IC and the (hopefully accurate) chelating effects of Brewtan.

Copper deficiency is more likely to strike in areas of the world with low endogenous copper in their water supply or they are using RO or DI for brewing. There have been many cases where sulfurous aroma is rapidly eliminated by allowing wort or beer to contact elemental copper. So having a low level of copper in your brewing water is a good thing. Its when its excessive that I can see this Fenton's reaction having a negative effect on beer.

I see that there are simple water test kits for copper content. I wish I knew what levels are appropriate or excessive. Sounds like this is a task for a brewer that used to have sulfur problems and has added some copper to their system to resolve it. A test of the raw water and a test of water or wort from their system, might give us some insight. Who in the forum has this condition?

Yeah, that I'm aware of.  But that assumes you have a sulfur issue to be dealt with.  I need to see more testing before I can accept that using an SS in and of itself increases sulfur.

I just wondered more about the lack of sulfur contact as opposed to the SS IC itself causing sulfur, Denny. For me, I'm sticking with my copper IC regardless.

I actually have 4 copper chillers around at the moment...3 IC and a CFC.  Obviously I'm not changing!
