Sounds good!
What effect do you get from flaked maize?Also, how easy is it to culture yeasts from commercial bottles? I have some experience in micro-biology and sterile / aseptic techniques, but with this kind of thing I always err on the side of caution. The last thing I would want to do is accidentally culture up a bottle of nasty by mistake.
Flaked Maize for head retention really, I would normally use Torrified or Wheat Malt, but flaked maize I find brilliant for lacing the side of a glass, keeping the head right to the bottom. After a pint has been finished you get gulp lines all the way down the glass that stays untilled rinsed off.
Culturing from a bottle is easy peasie. Be carefull with steralization and you will not go far wrong
You will need
a donor bottled conditioned beer
steralised jam jar
some preboiled and cooled wort or DME (spraymalt) aim for gravity of about 1020-1030 for best results
gas lighter
steralizer
1) wash donor bottle with sanitiser to get rid of as many nasties as possible.
2) flame around the metal cap (with bottle upright) to sterilize the top
3) ease the cap off trying not to bend it too much
4) pour your beer into a glass keeping the last few dregs in the donor bottle
5) replace the cap (it should just snap back on)
6) swirl the dregs around the bottom of the bottle and pour into some cooled preboiled DME solution
7) keep under an airlock and watch it fly.
once the initial fermentation has died down step up into a bigger jam jar or demijohn with a litre of wort or DME
You can use this method on your own bottled beers to keep favourite yeasts going :thumb:
