Has anyone read the Jan/Feb issue of Zymurgy? They have this article on "Stone Beer". Actually using very hot rocks to boil the wort.... you get them hot and toss them in the wort. Has anyone tried this?
Genghis77 said:Sounds like a rough way to boil the wort. I have heard of making coffee in plastic canteens with that same method. Guess you world need a way to fish the hot rocks out and reheat them or the pot would blow over.
Better efficiency...all of the heat in the rock goes into the wort, none is lost into the air. It's kind of like using an electric element inside your HLT.orfy said:One question.
Why?
I think I might have read that somewhere else (not Zymurgy). As far as asking "why?", haven't any of you ever gotten that question from someone drinking a Bud while you're brewing in your garage?DeRoux's Broux said:i think the rocks are supposed the caramelize the wort for the authentic flavor/effect of the brew.

BeeGee said:Come to think of it, I may have read about it in BYO's "10 Weird Beers" article from sometime last year. I believe the way that recipe went, you put the rocks in the kettle and then boiled it as usual. As DRB mentions, the rocks will heat up and caramelize the wort.

The article DRB and I read wasn't about heating the wort to boiling with the rocks (as the original post indicates), but just putting rocks in the pot while boiling which would create more hot surface area for the wort to come in contact with thereby caramelizing it more. I agree that heating just about any volume of wort to boiling with hot rocks would be a steep uphill battle!Denny's Brew said:You'd have to heat those little f'ers up pretty damn hot to get wort to boil, and have a very large pot to boot. Probably have to add several gallons worth (of pot capacity) of rocks.
That sounds like something interesting to read about...I wouldn't get too much further than that, either! Not even sure how to handle a 1000F rock. The BYO method of dropping them in your brew kettle seems feasible and interesting, but as I recall, the beer itself didn't capture my attention in the first place.SteveM said:The Zymurgy article does, in fact, suggest using very hot rocks - 600 - 1,000 F if I recall correctly - to boil wort. I got that that sentence of the article and could go no further. : )

Not to be nitpicky, particularly on a Friday, but my idea of caramelized onions is slow cooking them until the sugars naturally occuring in the onions caramelize as opposed to adding any additional sugar (unless I'm misreading your post). This post officially has nothing to do with beer or rocks :cross:Thor said:If you ever had caramelized onions (onions sauteed with sugar and butter/oil until the sugar darkens and thickens), you get the idea.
I have to agree with BeeGee on this one...don't be adding sugar (corn or otherwise) to your onions.BeeGee said:Not to be nitpicky, particularly on a Friday, but my idea of caramelized onions is slow cooking them until the sugars naturally occuring in the onions caramelize as opposed to adding any additional sugar (unless I'm misreading your post).

Walker said:I thought that caramelizing sugar ALSO changed the sugar, too. Ie; it makes longer sugar chains out of the previously smaller molecules.

Not possible for AG brewers who are pretty much required to do a full-wort boil.Swervo Maneuver said:If you want to caramelize your wort, why not do a 1/2 gallon boil?
