Biere de Garde is one of those beer styles that simply doesn't get a lot of attention. I'm not sure if it's either the middle of the road characteristics (it isn't especially strong/hoppy/roasty/yeasty) or that it is often the odd one out as the only distinctly French style. Whatever the reason, it's unfair since Biere de Gardes provide some of the best examples of malt complexity. There are some great imported examples of the style available for under $10 for a 750 (
3 Monts, Jenlain, and La Choulette) that are well worth picking up if you haven't tried them.
I've only brewed a Biere de Garde once before, and that batch was brewed to be blended into my
Cable Car Clone. With a sack of French pils on hand and a yeast cake of the Wyeast Kolsch strain from my most recent
batch of Kolsch, it seemed like the right time to give the style a real shot.

My recipe is based heavily on reading the excellent
Farmhouse Ales by
Phil Markowski.
According to the author the larger producers tend to employ simple recipes (almost all pils with a touch of dark malt for color and fermented warm with a lager strain), while smaller more artisanal producers go more complex (multiple specialty malts and fermented with ale yeasts).
The malt bill I selected was a bit more complex than I usually aim for, but it was based on the simple idea of making the beer as toasty/bready/malty as possible with additions of Munich, biscuit, and home toasted malt (Maris Otter baked in a 400 degree oven for 15 minutes). Home toasting malt is an easy way to add a unique touch to a batch, and something I should do far more often. I went with a lower mash temp to help dry the beer out while preserving the malty flavors. For the hops I decided on Brewer's Gold, but just about any European variety would have worked similarly well with such small additions.
Once fermentation is complete I'll lower the temperature close to freezing for a 4-6 week period of cold storage (which is what gives the style its name).

Notes
-----
9/5/10 Toasted several cups of Maris Otter in a ~400 degree oven on a cookie sheet on my pizza stone, stirring every few minutes. The grain popped a bit, it was the last of the bag and seemed a bit spongy. Cooked faster than I expected, was ready after 15 minutes or so.
Brewed 9/06/10 by myself
Collected 7.25 gallons of 1.058 wort with a fly sparge.
Could only chill to about 82, so I put it into the fridge set to 58 to drop the rest of the way below 70.
Pitched ~1/2 the yeast cake 6 hours later,shook and gave 30 seconds of pure O2. Left ~1 qrt of trub out of the fermenter. Hooked up a blow-off tube.
9/12/10 Down to 54 for primary on the Smoked Baltic Porter.
9/17/10 Upped temp to 60 to help it finish out.
9/24/10 Racked to secondary, still has a krausen, still really yeasty looking. Took out from fridge left at ~75 ambient to finish fermenting before cold crashing.
9/27/10 Down to ~1.016 (78% AA, 7.7% ABV). Still young and yeasty, but it has a nice fresh bread character.
10/3/10 Dropped the temp to 35 to start dropping out proteins/yeast. Shooting for 6 weeks of lagering before kegging.
11/13/10 Looks pretty clear. Racked to keg, and put on @10 PSI to carbonate.
12/16/10
Ended up really solid. Moderate sweetness (on the high end of the style), great malt complexity, and subtle fruit character from the yeast.
