Yes...thats exactly it.

You read between the lines on the name

Stuart Mackenzie is the father in "So I married an Ax Murder with Mike Myers....one of my favorite Scottish charecters.

And Old Chubby is of course a reference to Old Chubb....my second favorite beer.

As far as taste goes I don't know yet...I've done a lot of research on putting the recipe together and I think it should be excellent but I don't know yet..brew day is Saturday 5/7/11.

looks pretty good. I would probably choose a little english hop character over noble hops...but its been so long since I've had old chub I can't remember the taste that well. I would also lean towards some kettle caramelization or a longer boil. Regardless, looks like a good starting point...please let me know how it compares...a scottish ale is on my list to brew this summer.

Good points.

I had accomodated for the kettle carmeliization....I plan to reduce the first runnings volume from say 2 gals to 1.
