+1 on the "not that important" idea. I have used between 1.25qt/lb and 2.25qt/lb and not noticed an appreciable difference in mash efficiency. I've settled on ~2qt mark because the thinner mash is easier to stir and offers more even temperature distribution throughout the mash tun.
+1 on go with what you have.
I use a self-calibrated rod to measure kettle volumes. You need to find your system's boil-off rate, and kettle loss to trub, then factor those into each brew.
I mash tripels low, 149, to get a very fermentable wort and dry finish. The sugar also helps with this.
+1 on getting the spice from the yeast alone.
Have fun.
Gordon Strong reported on a BeerSmith podcast that he sets his brewing water to a pH of ~5.5 before he starts, eliminating much of the juggling with grains and salts changing the mash pH. He also spoke about holding out the dark grains until vorlauf which also helps keep the pH in an...
To me, it reads more like a smoked stout. Whatever you call it, I'd think it would be pretty smoky, roasty and full-bodied. I would also think that it would need to condition for a few months to round out the edges.
To the many great books already listed, I would add these:
Ivan Doig's The Sea Runners
Ken Kesey's Sometimes a Great Notion
Louise Erdrich's Last Report on the Miracles at Little No Horse
Cormac McCarthy's Blood Meridian and The Road
Most of what is on the report isn't very helpful. Phone the city water company and ask to speak with a chemist. Tell her / him that you need to know the ppm of these:
Calcium Ca
Sodium (Na)
Magnesium (Mg)
Chloride (Cl)
Sulfate (SO4)
Alkalinity (as CaCO3)
Then go to Palmer's "How to...
For most American and English ales, I use dry yeast and find them excellent and cost effective. For specialty ales I need the more specific strains only available in liquid form. They both have a place in modern homebrewing.
Sweet beginning to bitter end -> 6 hours.
Soon to upgrade from a turkey fryer to a Blichmann burner, and hoping that will shave half an hour to 45 minutes from current times.
BJCP style description for RIS indicates presence of dark fruit notes and esters -- something more than just burnt grain. Special B or C120 are malts you might consider working into your recipe.
When I started reading the style guide descriptions my brews began coming much closer to target...
