I was recently given a couple of cans of pre-hopped extract 4 gallon brews that are almost 10 years old. Has anyone her ever tried reviving one of these that are this old?
The first one is a Lager, which, to brew, is out of the question for me --- Tennessee Summers are hot and opressively humid if you come from Montana and where we live there's no AC, no internet, no work, no room to brew, no relief from the heat except cold homebrewed beer - or, in the alternative, cold water (and that stuff will rust your pipes!).
Since I've been told that the 10 yr old stuff may have lost much of it's hops value and maybe some of it's sugar values, I thought I might throw in an extra lb of DME (it's as old as these cans of malt), add some hops and new yeast (Munton's Dry Ale Yeast). All this may sound like heresy, but I don't waste things, especially free malt - even if it is 10 yrs old!.... I've been giving some thought to just brewing the old stuff with some fresh DME for the two lb of sugar it calls for (or maybe some Jaggery - [like Sucanat but with much more molasses] for the sugar), and some hops. Any idea of what hops I might use, since I'm planning on using an ale yeast to replace the old lager yeast? I like IPA's, Porters, and Stouts. Currently brewing a 1 gal Smoked Porter recipe modification from the book "Beer Craft" which is all about 1 gallon brews.
The plan would be a 10 day primary, 14 day secondary, and bottle condition for a month.
I've never dealt with pre-hopped 'kits' before --- I like All-grain and Partials, but have shied away from all-extract 'kits', and from what I read on the net, I shouldn't boil a pre-hopped kit, but just add boiling water to it as per the instructions. I'd like some input from the forum as to other opinions of how to try to revive these cans/kits. BTW, another can is Munton's Nut Brown which will probably be treated the same way but with dark DME or Jaggery instead of light DME if this first experiment works.
So Whatcha' think? Let me know soon, becuz I don't want it to get too much older!
