Wheeler's book, "Brew your own British Real ale" is kind of the the bible here.
But he never gives the yeast to use. Saying (elsewhere) that homebrewers probably wouldn't have access to the yeasts which the breweries were using.
Timothy Taylor Landlord 4.2%, is my favourite pub draught beer. When it's stored and served well.
Living in Scotland, where TTLL, isn't available on tap locally (the nearest place I know is near Penrith, nearly 300 mile away). So I've been trying to come up with a decent clone.
Once I switched to the right yeast (one which was derived from the TT brewery), Wyeast 1469 West Yorkshire. The result was amazing.
