A top down look at the lid
Bottom side of the lid. Notice the white o-ring that fits into the lip of the lid.
I received several extra airlock grommets. I found it easiest to install the airlock when it is wet. Installing a dry airlock ended up damaging the grommet. A sanitizer soaked airlock fixed that problem as it slid in easily without damaging the grommet.
The Cavern has a plastic ring around the bottom, presumably to protect it from getting dinged or dented. Good idea.
Here’s a picture of the optional ball valve installed in the lower of two 1/2″ NPT ports. It’s difficult to see in this picture (and in person), but there is what I would call a slight dent between the two ports. I asked the Deep Woods Products about this and was told “We have had a few that have a very slight indentation. This was created when we bored the two ports into the stainless steel. Due to the tension on the stainless steel and the wall thickness this created a slight indentation between the two ports. This will not affect the performance of the cavern one bit. Its more of a cosmetic issue.” At least on the one I have, you really need to look closely to notice this.
The whole thing assembled.
This is more of a first looks type post since I haven’t had the chance to try fermenting a beer in my Cavern yet. I’m looking forward to giving it a try on one of my next batches.
My first impressions are very good. This is another Deep Woods product that I was wowed by the first time I saw it – stainless bottles being the first. Considering it’s all stainless construction, this is a relatively inexpensive way to get into fermenting in stainless, as compared to stainless conical fermenters.
These come in 5, 10 and 12 gallon versions. The 5 gallon version has two ports and the 10 and 12 gallon versions have one port each.
