I apologize to everyone else here for attracting angry remarks to this great forum. I didn't have a squabble elsewhere and bring it here to ruin everyone's day. There was no squabble. I don't do that. I'm grateful for forums, and I respect the proprietors' right to good behavior from members like me who pay nothing to use them.
I do disagree with people, politely. Most people handle it well.
Can you quote and link to the forum post where your being told "BIAB wasn't as good because I couldn't do a step mash" and "BIAB provides no mash temperature control".
Tone down the slander.
Try calling MoreBeer instead of just browsing their website. They should be able to order an o-ring for you.
That is really rude, not to mention the weirdness of chasing me from another website and trying to start a fight and hijack a thread. I was never anything but polite and cordial to you, and I haven't said anything here that was insulting or dishonest. Why ruin the atmosphere of a friendly forum?
On top of all that, what you're implying is not true:
A simple one pot BIAB approach like you've discovered does have the advantage of a quick cleanup however you'll also have to deal with:
Uneven mash bed temperatures
No recirculation
No mash temperature control
No pre-heat (delay timer)
No pump to move the wort
No step mashing
"Slander"? Seriously? That would be over the top even if I had lied about something this microscopically unimportant. I make an honest, polite effort to get some useful brewing information, and I get chased down and accused of tortious behavior.
Slander is actually called "defamation" these days, and back when other terms were popular, they called written defamation "libel." "Slander" was almost always reserved for oral defamation. A defamation plaintiff has to show economic damages. Also, truth, or substantial truth, is an absolute defense. A lot of defamation suits die from motions to dismiss because defendants proved they were truthful.
I'm going with the free-shipping generic O-ring I already ordered instead of hassling myself with Morebeer, waiting for them to get a ring from Germany, and paying their shipping charge. Ebay took a couple of minutes. Done.
If I ran Speidel, I'd just tell people what part to buy locally. I don't know about Germany, and I realize they have a different outlook, but in the US, informing customers they can use generic parts is SOP for many companies. Speidel is doing business in Rome, so it should do as the Romans do. Some poor guy paid them a couple grand for this severely-overpriced machine. My guess is that they don't need to dive for every pfennig.
Imagine, expecting a customer to miss a week or more of brewing so your company can make a Euro and a half and protect the amazing trade secret of using a 60mm x 54mm buna O-ring. It's tone-deaf. It's not like I asked KFC to send a list of the 11 herbs and spices. Everyone knows the company that makes Speidel's pumps buys O-rings off the shelf. They have never made an O-ring or developed a special material.
