Brewing with Hot Rocks!!
LHBS Apex Brew Wares put on their second Stein Brew Last night. Brewing with hot rocks. We boiled the wort using rocks heated from a fire. Thought I'd post some pics up for everyone here to see. Very interesting. Couple guys from the board were there that I've met before and know, KCBrewer, Schumed, Apex. If I missed some other guys sorry.:D

Was a pretty simple malt bill, only one hop addition. Was an awesome, fun, and interesting time to see how it can be done. If anyone else there got some pics put them up!

You guy's have any rocks blow up? I used to be an archaeologist and one of the most common things to find were fire cracked rocks, caused by people doing exactly this. Maybe just not with beer :D. Looks pretty awesome!

Interesting. I'd love to hear what type of flavor the fire heated rocks impart.

I'm guessing piney, since they're using two by fours.

Very cool. I'm an archaeologist and some of my research focuses on hot-rock cooking. As jskinner said, fire-cracked rock (or just FCR, as we call it) is one of the most common artifacts we find, especially in certain time periods. I've never brewed beer with hot rock, but I've done other experiments using it as a heat source for cooking. The first time you try "stone boiling," it's really quite surprising how efficient it is and just how quickly you can bring water (or beer, or venison stew) to a boil with hot stones.

Keep up the good work! :mug:

Those last few pictures are badass!

I assume it might be a bit smokey as well.

The guys from basicbrewing radio did an audio and video podcast of stein brewing with F.O.A.M.
The Fellowship of Oklahoma Ale Makers. It's in their archives from 11/10/2010. Was a pretty interesting watch and listen.

Nice kettle lid.

I'm really interested to hear how long it took to bring the wort up to boiling. Like HeadyKilowatt, I've done experiments involving boiling water with hot rocks as well and it's definitely surprising how quickly you can bring water up to boiling temperatures. However, I wasn't trying to boil a volume even close to what landshark was involved with.
