In Recipes are categorized into three general, de Garde produces three recipe typesstyles; Berliner berliner weisse/gose-inspired, saison-inspired, and lambic-inspired. As the brewery grows and matures, Rogers plans to phase-down or phase-out the Berliner berliner weisse/gose-inspired beers, giving more focus and attention to saison-inspired and lambic-inspired beers. The former were produced out of necessity for quick turnaround production but it is not where de Garde's heart is. The brewery recognizes the Berliner berliner weisse/gose-inspired beer popularity with customers, therefore still plan to produce several batches per year. The end goal is to have the lambic-inspired beers represent a significant majority of the production <ref name="thesourhourthesourhour1"></ref>.

Before selecting a physical home for the brewery, Rogers wanted to qualify potential locations for spontaneous fermentation character. He exposed sterile wort to ambient microflora in various towns along the Oregon Coast <ref name="craftbeertemple"></ref>, originally considered for its consistent year-round temperature and climate <ref name="bierversuche"></ref>. Using a grist of pilsner and wheat, Rogers brewed 15-gallon trial batches on a MoreBeer! Tippy-Dump BrewSculpture. The wort was chilled and split into food grade buckets, standardized to 1-gallon volumes for consistency. The buckets were brought to prospective locations and left uncovered overnight, emulating the function of a coolship. Once retrieved, the beer was allowed to ferment for approximately 12 months before undergoing sensory assessment to understand the unique representation of ambient microflora from that area. Rogers noticed a distinct sensory difference in spontaneously fermented trial beers in as few as 10 miles apart <ref name="craftbeertemple"></ref>. This trial batch method allowed Rogers to refine his list of prospective locations and repeat batches to qualify consistency <ref name="bierversuche"></ref>. Ultimately, Tillamook was selected for its desirable microflora character and shorter fermentation timeline <ref name="beerandbrewing">[https://beerandbrewing.com/breakout-brewer-de-garde-brewing/ Breakout Brewer: de Garde Brewing. Retrieved 2/25/2018.]</ref>.
De Garde initiated brewing operations in 2012 in downtown Tillamook using a 7-bbl brewing system. Their initial focus was to brew a wide variety of clean beers and spontaneously fermented beers <ref name="newschoolbeer"></ref>, however the early success of initial spontaneous batches encouraged the shift to a singular focus. Rogers specifically credits the first batch of Bu Weisse, brewed on a whim to determine brewhouse efficiency and specifications, for reinforcing his desire to pursue spontaneous fermentation exclusively. By 2015, the Bu Weisse beers represented 15-20% of total production, quickly becoming de Garde's flagship beer <ref name="craftbeertemple"></ref>.
Today, de Garde is motivated to be as close to an authentic [[Lambic | lambic ]] brewery outside of Belgium. They rely strictly on ambient microflora to create a local manifestation of spontaneously fermented beer <ref name="thesourhour1">[http://www.thebrewingnetwork.com/the-sour-hour-de-garde-brewing/</ The Sour Hour Episode 20- De Garde Brewing.]</ref>. As the brewery matures, production and sales should converge to approximately 1,300 - 1,400 bbls per year <ref name="thesourhour2">[http://www.thebrewingnetwork.com/the-sour-hour-episode-21/</ The Sour Hour Episode 21- De Garde Brewing.]</ref>.
The name de Garde is inspired from the concept of beers destined for keeping, holding, and cellaring – a reference to the breweries who have inspired Rogers in both process and product. De Garde purposefully brews beers that will evolve over time, giving credence to both inspiration and reality <ref name="craftbeertemple"></ref>.
90 to 95% of of the grist used in de Garde's beer is Northwest grown and/or malted <ref name="thesourhour2"></ref> and only some recipes use raw grain, such as unmalted wheat in Saison Premiere <ref name="craftbeertemple"></ref>. Oats are sometimes used to reduce dryness <ref name="bierversuche"></ref>.
De Garde prefers three or four-year-old aged Cascade or Willamette hops for most of its recipes. Rogers is not particularly fond of the cheesy character of aged hops, instead preferring a wild, earthy, and herbal character. In his experience, aged hops can also contribute noticeable tannins, particularly in more aggressively hopped beers <ref name="thesourhour1"></ref>. Beers are hopped at 1.5-3.0 lb/bbl (0.8-1.5 oz/gal), with the latter representing the rate used in lambic-inspired beers. Brewers have progressively increased the hopping rate over the years to prevent beers from becoming too acidic. Bales of aged hops are lab-tested for de Garde to ensure they are not too aggressive or mild <ref name="bierversuche"></ref>. Occasionally, non-aged hops are used at the end of the boil, in the whirlpool, or dry hop for fresh hop character. This is common in some [[Saison | saison]]-inspired recipes <ref name="thesourhour1"></ref>, such as Azacca in Saison Troisieme, designed to marry the fruity yeast esters with fruity hop flavors <ref name="craftbeertemple"></ref>. In Spears, de Garde used a total of 5.0 lb/bbl (2.6 oz/gal) of hops <refname="talkbeer">[https://www.talkbeer.com/community/threads/de-garde-brewing.5908/ Talk Beer - AMA De Garde Brewing. Retrieved 3/2/2018.]</ref> (Post post 164405).
Rogers is not averse to using imported ingredients, such as European malts and hops, when no suitable domestic substitute exists since it contributes to the overall quality of his beers <refname="talkbeer">[https://www.talkbeer.com/community/threads/de-garde-brewing.5908/ Talk Beer - AMA De Garde Brewing. Retrieved 3/2/2018.]</ref> (Post post 182214).
Tillamook water is mineral deficient much like distilled water. Rogers does not treat the water for the vast majority of recipes because he wants the beer to be an authentic representation of the environment <ref name="thesourhour2"></ref>.
Rogers experimented with traditional [[Turbid_Mash | turbid mash]] regimens but switched to a modern approach instead <ref name="beervana">[http://beervana.blogspot.com/2016/11/the-spontaneous-files-de-garde-brewing.html The Spontaneous Files: De Garde Brewing. Retrieved 3/3/2018.]</ref>. He uses a typical mash procedure <ref name="thesourhour1"></ref>, featuring a higher-than-normal mash temperature, bordering on the edge of denaturing conversion enzymes, for most beers <refname="talkbeer">[https://www.talkbeer.com/community/threads/de-garde-brewing.5908/page-4#post-163644 Talk Beer - AMA De Garde Brewing Post 163644. Retrieved 3/2/2018.]</ref>(post 163644). In general, de Garde produces wort that "could be found at almost any brewery" with the exception of more adjuncts, such as wheat. Mash pH is adjusted on occasion, specifically for the [[Berliner_Weissbier | berliner weisse]]/[[Gose | gose]]-inspired recipes since brewers intentionally avoid the enteric bacteria phase of spontaneous fermentation to shorten fermentation duration and produce less funky character. It is important to note, however that no pH adjustments are made after the mash <ref name="thesourhour1"></ref>. The berliner weisse/gose-inspired beers are mashed at 150°F for a longer duration for a more fermentable wort <ref name="thesourhour2"></ref>. The Lambic-inspired beers are an entirely different recipe designed to be slightly less fermentable <ref name="thesourhour2"></ref>. A hot sparge is used to rinse the grain <ref name="thesourhour1"></ref>.
Brewers do not oxygenate the wort <ref name="craftbeertemple"></ref>. Post boil, the wort is transferred into the coolship, typically around 3-4 pm. Upon entering the coolship, the wort is still at near-boiling temperature. The next day the wort is removed from the coolship around 12 pm (after ~20 hours), though overnight ambient temperatures can impact the cooling rate and exact removal time. Every de Garde beer runs through the coolship <ref name="thesourhour1"></ref>. The ~14 bbl coolship was built by Practical Fusion in Hillsboro, Oregon <refname="talkbeer">[https://www.talkbeer.com/community/threads/de-garde-brewing.5908/page-22#post-737875 Talk Beer - AMA De Garde Brewing Post 737875. Retrieved 3/2/2018.]</ref>(post 737875). Prior to having the coolship installed, de Garde used their 7 bbl Hot Liquor Tank and Boil Kettle (which featured removable tops) for spontaneous inoculation. They equalized the volume between the two vessels to give a higher surface area to volume ratio <refname="talkbeer">[https://www.talkbeer.com/community/threads/de-garde-brewing.5908/page-6#post-169003 Talk Beer - AMA De Garde Brewing Post 169003. Retrieved 1/27/2018.]</ref>(post 169003).
For the berliner weisse/gose-inspired beers, the coolship inoculated wort is transferred back into the kettle and held between 100-120°F (with 110°F as a target) for approximately 48-72 hours to encourage acidification from ambient lactic acid bacteria. This contributes to a relatively clean, yet still slightly funky character in the beer. After the warm temperature hold is complete, the wort is transferred to oak barrels and allowed to cool naturally <ref name="thesourhour2"></ref><refname="talkbeer">[https://www.talkbeer.com/community/threads/de-garde-brewing.5908/page-12#post-194702 Talk Beer - AMA De Garde Brewing Post 194702.

All oak vessels go through a full sanitization regimen before first use and between subsequent uses. A high pressure wash of 180°F is applied to inverted barrels for 20-30 minutes. Despite this process, Rogers has noticed ''[[Brettanomyces]]'' character expresses itself earlier in subsequent barrel uses. Barrels are stacked to a maximum of three levels high to help maintain consistent temperature throughout<ref name="craftbeertemple"></ref>.
