In 2012, Linsey and Trevor Rogers founded '''de Garde Brewing''' in Tillamook, Oregon. De Garde is often considered the first exclusive [[Spontaneous_Fermentation|spontaneously fermented beer]] producer in the United States, despite initial intentions to also produce conventional beers<ref name="wweek">[http://www.wweek.com/outdoors/2016/05/27/tillamooks-de-garde-might-be-the-worlds-quirkiest-brewery/ Tillamook's De Garde Might Be the World's Quirkiest Brewery.

Brewers do not oxygenate the wort <ref name="craftbeertemple"></ref> (~27 min in). Post boil, the wort is transferred to into the coolship, typically around 3 or -4 pm. Upon entering the coolship, the wort is still at near-boiling temperaturestemperature. 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 <ref name="thesourhour1"></ref>(~24 min in). Every de Garde beer runs through the coolship <ref name="thesourhour1"></ref> (~23 min in) <ref name="craftbeertemple"></ref> (~3 min in). The ~14 bbl coolship was built by Practical Fusion in Hillsboro, Oregon <ref name="talkbeer"></ref> (page 22 post #421). 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 [[Coolship#Surface_Area_to_Volume_Ratio | surface area to volume ratio]] <ref name="talkbeer"></ref> (page 6 post #111).

For the Berliner Weisse/Gosegose-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 to -72 hours to encourage [[Wort_Souring | 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 [[Barrel | barrels]] and allowed to cool naturally <ref name="thesourhour2"></ref><ref>[https://www.talkbeer.com/community/threads/de-garde-brewing.5908/page-12#post-194702]</ref>. Every De Garde beer runs through the coolship (~22 min in) <ref name="thesourhour1talkbeer"></ref>.

The inoculated wort is transferred directly into various sized oak vessels including standard wine (~60 gal) and spirit barrels (~53 gal), puncheons (~120 gal), or foeders (~1,800 gal) <ref name="thesourhour1"></ref> (~25 min in) <ref name="craftbeertemple"></ref> (~3 min in) <ref name="talkbeer"></ref> (page 5 post #92). Consistency between recipes beers aged in barrels and foeders is very high <ref name="craftbeertemple"></ref>(~28 min in). The brewery nearly exclusively uses Northwest-sourced barrels <ref name="thesourhour2"></ref> (~33 min in). Some non-neutral barrel types used include cognac <ref name="thesourhour1"></ref> (~45 min in), gin <ref name="thesourhour2"></ref> (~28 min in), rum <ref name="talkbeer"></ref> (page 3 post #59), and bourbon <ref name="beerandbrewing"></ref>. De Garde especially enjoys the synergy between gin and hops which is why they age most of their hop-forward beers in gin barrels <ref name="talkbeer"></ref> (page 4 post #78). 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 <ref name="craftbeertemple"></ref> (~15 min in). Barrels are stacked to a maximum of three levels high to help maintain consistent temperature throughout <ref name="craftbeertemple"></ref> (~30 min in). Most of de Garde's beers go through a ropy period in the barrel, indicating the presence of ''[[Pediococcus]]'' <ref name="talkbeer"></ref> (page 2 post #29).

De Garde often fills empty foeders with multiple batches over as long as a week. Often by the third batch, vigorous fermentation is already occuring occurring inside the foeder <ref name="craftbeertemple"></ref>(~26 min in).

Beers De Garde commonly adds [[Soured_Fruit_Beer | fruit]] to their spontaneous beers, using ratios inspired from Belgian lambic producers. Their default [[Soured_Fruit_Beer#Usage_Suggestions | fruit-to-beer ratio]] is 2.0 lb/gal with exceptions for aggressive fruits (cranberry and currant) at 1.0 lb/gal and delicate fruits (peach) as high as 4.0 lb/gal. Brewers use a variety of fruit formats but prefer fresh or frozen. Purees are fermented occasionally used for beers due to seasonal limitations <ref name="thesourhour2"></ref> (~30 min in). Rogers prefers frozen fruit for its enhanced color and aged flavor <ref name="talkbeer"></ref> (page 22 post #421). He is particularly fond of wine grapes (due to his love of wine), especially grapes that express a strong sense of terroir <ref name="talkbeer"></ref> (page 2 post #22). Beer is conditioned on fruit until the lees and the ambient microflora desired character is never repitched into subsequent beers obtained, ranging from one week to three months <ref name="thesourhour1talkbeer"></ref>(page 12 post #227).

Barrels go through Rogers believes that the bottle conditioning process is one of the most fragile states of spontaneous beer production <ref name="thesourhour2"></ref> (~15 min in). De Garde originally packaged beers in 750 ml Belgian-style amber bottles with a crown but have since moved to amber champagne bottles with a full sanitization regimen before first use cork and crown.

It is rare to dump and entire batchA large percentage of bottles undergo a second ropy phase, often just individual barrels from a batch once again hinting at the presence of ''Pediococcus'' in de Garde beers <ref name="craftbeertempletalkbeer"></ref>(page 2 post #29). Most of de Garde's beers go through a ropy period in the barrel <ref>[https://www.talkbeer.com/community/threadsThe Berliner Weisse/de-garde-brewing.5908/pagegose-inspired beers spend between 2#post-160189]</ref>. Rogers has intentionally left barrels exceed the four-year mark to see how they will evolve. He willingness to gamble at times is a direct desire to make the best beer possible 8 weeks in bottles before being released <ref name="craftbeertemplethesourhour2"></ref>(~23 min in). Rogers believes recognizes there is going to be a natural blend-to-blend and bottle-to-bottle variation with spontaneous beers and that most it's not a flaw rather just part of the ambient microflora comes from the brewhouse itselfprocess. He looks for a re-supply believes you lose the greatness of enteric bacteria via coolship for added complexity of character spontaneous beer if you try to produce the same thing every time <ref name="beervanabierversuche"></ref>.

(In progress)<br>

De Garde regularly brews about one dozen different base recipes with slight variations <ref name="bierversuche"></ref>, though in 2014 they brewed over 100 unique recipes, a testiment to their willingess to try new processes and techniques <ref name="craftbeertemple"></ref> (~20 min in).

In Recipes are categorized into three general, de Garde produces three recipe typesstyles; Berliner weisseWeisse/gose-inspired, saison-inspired, and lambic-inspired. The Berliner Weisse/gose-inspired beers are designed to be highly fermentation to encourage lactic acid production. The lambic-inspired beers are the opposite; less fermentables encourage a greater depth of ''Brettanomyces'' character <ref name="thesourhour1"></ref> (~48 min in). As the brewery grows and matures, Rogers plans to phase-down or phase-out the Berliner weisseWeisse/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<ref name="thesourhour2"></ref> (~24 min in). The brewery recognizes the Berliner weisseWeisse/gose-inspired beer popularity with customers, therefore still plan to produce several batches per year<ref name="thesourhour2"></ref> (~26 min in). The end goal is to have the lambic-inspired beers represent a significant majority of the production <ref name="thesourhourthesourhour1"></ref>(~46 min in).
