A little footnote if I may. I used to culture (20 years ago Arrghh was it that long) from Shepherd Neame's Spitfire when it was bottle conditioned, all I did was stick the dregs into a starter solution (malt extract, water and a little sugar) wait three or four days and chuck it in, things were a little less scientific then but boy did it create good beers. I never tried to re-harvest or anything like that but it was a great yeast back then and assuming the same strain I reckon it will still be good.
Well, it's made a cracking brown ale
