Oak TheoryOak Theory
Notes: This beer is our take on classic Belgian sour beers from the Senne Valley. We combine Colorado pilsner malt and raw wheat with a hefty charge of aged European whole hops and boil for almost 3 hours. We ferment in a variety of different sized oak barrels with a proprietary blend of saccharomyces, brettanomyces and various lactic acid bacteria cultures. After aging in these barrels for anywhere from 9-12 months, barrels are selected for their unique flavors and that individual blend is born.

Bottle from 3/17/16.

Poured golden with a white head. Very clear without the dredges. Aroma is slight barnyard funk and oak. Some noticeable stone fruit. Taste is smooth tart lemon and funk on the back end. Finishes dry. Very fitting medium carbonation. Very drinkable with little noticable alcohol. I could drink this all day long.

Bottle: Poured a hazy yellow color ale with a medium size head with limited retention. Aroma of tart and sour notes with some oak. Taste is a mix of tart notes with some oak, some medium intense acidic notes with some light funky notes. Body is about average with OK carbonation. Interesting and complex but lacking some attenuation and a bit too acidic for my taste.

One line review: this beer feels like training wheels for people that are afraid of hopping on the gueuze bicycle.

Muted doses of sour apple and lemon zest both on the tongue and nose. There are hints of bretty barnyard funk toward the back end as well, but the flavors aren't as persuasive or demanding as they would be in the Belgian counterparts that the beer is attempting to emulate. The balance of flavors reminds me of Oud Beersel Oude Geuze -- well-rounded with all the flavors mostly staying within the lines.

The brew honestly feels more like a table beer than anything. It smoothens out all the elements of the Belgian style that the average drinker may feel adverse to (acidity, sharp tartness, funky oak) and turns it into a fine sipping apéritif designed to get the taste buds going before a big meal.

As the alcohol content and the price of this beer equals the standard ABV and cost attributed to most gueuze and lambic-style brews, I might venture and say this is to Hibiki 17 what a gueuze is to Yamazaki 18.

Bright pastel yellow with a clingy, creamy soft white ring.

Smell is maple, oak, wood, and almond funk transitioning on the palate to very tart lemon and grapefruit, finishing dry. Wow. Crazy complex!

Bottle dated 12/22/2015; opened on 2/5/17 and poured into a SARA glass. Nose of lime, green apple, oak, and funk. Palate starts with strongly acidic lime and vinegar, moving quickly into green apple which then lingers, followed by mild oak and funk. Not one for lime or green apple flavors in my beer, I’m having a hard time enjoying this.

Bottled 3/23/15. Pours a translucent honey color with a half inch, off-white head. Nose is fairly subdued but suggests green apple cider. Taste reveals vinegar notes, hay, a hint of Brett and tart green apples. Mouthfeel light and spritz with a mild acidity. Overall, not particularly complex; however, makes a nice introductory sour.

Light golden body with nary a head. The aroma smells like an authentic gueuze lambic. Oak is prominent. Tart green apple and a hint of white wine. Mild acetic finish. What a lovely beer.

This one has a sticker that says First! on it. I have had the dry hopped ones and I think this is better. It is more of what the beer should be. Great balance of sour, tartness, fruit, and funk. Very easy to drink. Nothing extreme. Just a solid enjoyable american wild ale.

Pours a slightly hazy pale yellow golden color with fizzy white head. Funk, plenty of tartness, and citrus on the nose; follows onto the palate. Light bodied. Finishes tart and dry,

One of my favorite unfruited sour beers. One of the funkiest too. Smells like old dirty sponges that were left wet in the bottom of a industrial kitchen sink, like hay-laden horse manure, and a crowd of variegated soiled barnyard beasts. Amazing. Would have thought it older than a year, but I felt the same about Beatification, to which I would compare this. Whatever Troy Casey is doing, he needs to keep this up. Gueuze-like and tart, and maybe it's the power of suggestion but it's darn oaky too. Perfectly crafted, blended, and nomenclatured beverage.

A really nice, basic sour.

Very tart on the palate -similar to Side Project's foedre beer, with an apparent oak barrel presence.

Maybe a bit overpriced for what the beer offers but still a an enjoyable bottle.

Lovely drinking tart ale, oak there and balanced and not as much as expected. Drunk in honour of Josh Oakes birthday, cheers! Wild yeast aroma. Really surprising drinkability and masterful.

The aroma offers apricot, lemon tartness, soft funk.

The flavor follows with fuzzy peach skin, medium plus lemon tart, drying oak on the finish. A really balanced on tart qualities, some hints of fruit, and a dry and oaky finish.

Very clear, yellow color. Nose is a very potent sour/citrus. The taste is a smooth sour with a very late hint is berries. Mouthfeel is beautiful. An awesome beer.

Lemon, green apple, lacto and oak. Super clean finish. Want something more from this. It's still pretty good but the dry hopped version is better.....

Bottle shared by Curran last night, thanks man.

This one pours a clear glowing dark yellow, with a small head, and a little bit of lacing, but not a whole lot.

This smells like sour citrus, mostly orange and lemon, oak, some grain, and white wine.

This is another winner from Casey. The blend makes for a really nicely rounded wild here, pleasant, soft citrusy acidity, some pleasant graininess, a bit of oak, and some light white wine character. This can be best described as pleasant. Just really well-balanced and not overly sour, probably a 5/10 on the sour scale.

This one is pretty light bodied, airy and fluffy almost, with a juicy mouthfeel, and a moderate level of carbonation.

An excellent and superbly drinkable wild ale here. Casey is one of the best wild producers in the country.

Thanks to GRG1313 for sharing this one at his tasting.

Bottled 4/14/15.

Pours a clear yellow-orange with a foamy bone head that fades to nothing. No lacing on the drink down. Smell is slightly sour with grain, funk, earth, and hay aromas. Taste is much the same with sour grain, fruit, funk, and wood flavors on the finish. There is a mild amount of acidity on the palate with each sip. This beer has a good level of carbonation with a crisp and dry mouthfeel. Overall, this is a very good beer with a solid mix of sour, funk, and wood characteristics that are slightly better in the taste to me.

Serving type: bottle.

Pours a hazy medium yellow body, one finger white head. Nice retention and a bit of lacing. Smells very tart, like a yellow sour patch kid. Lemon, oak, a bit of lactic acid, moderate acetic character. Very much in your face acidity, but in a pleasant way. Flavour is oak, lemon, must, hay, vinegar, a small bit of lactic acid. It started out quite funky, with a good bit of hay and must; reminded me of a Belgian geuze in some ways. Warming up though, it becomes more lactic like a standard AWA. Still a delight to drink. Mouthfeel is medium bodied, moderate carbonation, soft and easy to drink despite being fairly acidic. Overall, this is a very good AWA with a lot of geuze characteristics when served chilled, so I would recommend enjoying it chilled and as it warms up. It's a real trip.

bottled 2/19/15, drank 6/12/15. Purchased along i70 corridor in Coloardo

The smell is f*cking glorious. Overall its a very nice lambicy/geuzey like wild ale, however for my taste there is alot of acetic acid character. While i think this is good, it was very expensive. Worth trying, but dont trade a kidney for one

Light Orange/golden. Big artificial head induced from aggressive pour, no head besides that.
Smells super funky, tarty.
Lemon grass at the forefront, turns to pure funk. Like '70s stylee.
Medium bodied sour, low carbonation.
Very nice oaky sour from Casey, my first from them. Would drink again. Thanks Jim.

A: not a lot of head or effervescence hazy golden/hay

S: kinda goozie cheesy w apparent acidity and oaky woo

T: great funky then mild to mid acidity lemony cheesy waves into late oak barrel. Mild hoppiness throughout

M: pretty dry and acidity lingers

O: really great but doesn't fully get on the musty hoppy goozie level that Cuvee St-Gilloise delivered on next bottle afterward. Would seek out however!

Reviewed from notes. Citra and Simcoe hops. Poured clear piss-pale yellow with a tiny white foam around the edges. Tannic, tart finish and refreshing.
