I think I'll try North American 2-row first, although I understand that 
6-row has even more diatatic power.  Two-row will give me an opportunity 
to experiment with some of Jeff Renner's historical American styles 
without having to mess around with a protein rest.  I've got a beverage 
cooler mashtun and haven't yet worked out water infusion temperature 
manipulation to my satisfaction.

I made the 1850 Whitbread London Porter this weekend and am pleased to 
report that Maris Otter (79% of grist) was sufficient to convert the 
brown malt I added (15.5%).  I normally get around 65 - 68% extraction 
efficiency and this batch was 70%, so I think the pale malt did it's 

A much harder challenge will be allowing this beer to sit in the bottle 
for 4-5 months according to the aging time for the recipe!
