LHBS (they do more wine than beer) has some old canned extract kits that have expired (within past couple of months) marked down to $7 for a 4lb can. I know everybody says to only use fresh extract - but from a taste perspective, what problems come from old extract? I assume color may darken / change. Any other potential problems? I checked their stock today, and none of the cans were bulging or showing signs of spoilage / leaking.
My main concern is just not making something bad, and worst case, I still get a starter out of it. I am thinking of getting one to do a quick 2-3 gal batch, partially for the beer, partially as a BIG starter for a higher gravity (1.080+) Baltic Porter that is on my horizon. They had Ironmaster Special Bitter & IPA; John Bull, Edme, and Coopers wheat; and Laaglander Bock. I am leaning towards either one of the Ironmaster kits or one of the wheat kits . Haven't bought a kit can for long time (usually use Alexanders plain), so not real familiar. A can isn't much more than a pound of DME, which I would need to buy for a regular starter anyway. If I can get him to throw in a pound of specialty grain with the kit, then what do you all think? This is only for a quick, cheap drinkable (nothing fancy) brew / starter, not a specific stylisticaly correct competition beer.
I am shooting for a brew with an OG of 1.040 (in line with a starter) which means about 3.5-3.75 gal batch. I will probably throw some flavor / aroma hops in I have left over to liven it up a little. I am thinking of using liquid CA Common yeast (which was out of stock), or German Lager WLP830 or Czech Lager WLP802 or Zurich Lager WLP885 (which they had).
