These two single-walled horizontal lagering tanks are GREAT for tucking beer away and letting it cold age.  They have a 30 hectoliter (25 bbl) capacity each, and 15 psi rating (photo of spec plate included).  They are on wheels and can be easily moved by one person empty and two people full.  So you can roll them back to that unused corner of your cooler and let your Märzen mellow-out until Oktoberfest without taking up brite tank space!

Price is $4,250 each.
