Sour Grand SaisonSour Grand Saison
Notes: he brewers of Grand Teton started by reproducing The Grand Saison 2011 recipe. The first “thread” follows centuries of tradition, using European hop varieties—German Hallertauer Tradition, UK Goldings, Czech Saaz and French Strisselspalt. They used a very light base malt accented by just a touch of German Wheat and Munich malts. Finally, they fermented it very warm with a classic Belgian yeast strain to bring out the spicy flavors that are common to saisons.

The second “thread” fermented with Brettanomyces Drei (also known as Brettanomyces Trois.) This wild yeast from Belgium produces a very delicate tartness with lovely aromas of tropical fruit like mango, peach, pineapple and guava.

Finally, Grand Teton’s brewers produced a third “thread” of saison, this one soured with Lactobacillus, a common and beneficial microorganism that we encounter every day. It gives yogurt its tang and helps to ferment pickled vegetables such as sauerkraut. In Grand Teton’s Sour Grand Saison, Lactobacillus provides a delightfully tart, tangy and crisp, citrusy-sour flavor.

Each of the three “threads” were carefully tasted and combined to create the wonderfully complex and delicious Sour Grand Saison.

Four plus fingers of fluffy white head lasts a very long time. Rapidly rising clouds of fine carbonation add texture to the iridescently clear amber beer (SRM 6-8). A thick patching of lace adds geography to a Cisco fisheye pint glass. The head eventually becomes a sparkling meringue.

Fermented orchard fruit such as apricots and peaches dominate against wheat and brettanamycies. Pepper and celery are firmly in the background with lemongrass.

The sourness is modest, more tart than sour.

There is a nice bite of bitterness which balances well against the sweetness. Lemons seem to be the solitary fruit, with strong grain flavor reminiscent of Triscuits and Wasa Rye Crisp crackers. The mild, lingering, dry finish carries celery. Warmth brings out a light curry and accentuates the acidity. A medium to full body with an itchy, wool texture. Alcohol is within expectation, with a slight nibble of carbonation that is fizzy and fine.

This is a solid Saison with lots of subtle components and a few bold ones. The sourness is less than I anticipated from the label, and was a pleasant addition to a cool, sunny afternoon after a hard day in the yard.

Bottle was sampled three years after packaging.

No time for the big review but nice fluffy head with champagne bubbles. Great barnyard, fruity, sour aromas. Tastes almost as good as it smells and feels nice going down. Tempted to buy a case of this one.

2015 cellar reserve.

Pours a beautiful straw orange with a fluffy effervescent head. Gorgeous!
Smells wonderful, spice, earth, huge sour overtone.
Nose is slightly tart but no overwhelming sourness. Light and fluffy and wonderful.
Wonderful beer with no hint of booze. Perfectly sour. In love with it. Not rated highly enough.

4.19/5  rDev +6.9%
look: 4.5 | smell: 4.25 | taste: 4 | feel: 4.5 | overall: 4.25

Appearance: A bit of a foamer but it settles down quickly, in the bottle; pours a cloudy honey color with a massive head; gobs of lacing hang around

Smell: Wild yeast dominant, with bread, lemon, tropical fruit, grass, leathery funk and grainy tones

Taste: Lactic lemon and tropical fruit tones; grainy, grassy and funky through the middle, with peppery spice developing, after the swallow; a hint of vanilla but the Brett is pronounced; definitely some band-aid phenolics in the finish

Mouthfeel: Medium body with moderate to high carbonation; very Belgian

Overall: A lot going on here and I think the beer is starting to come together (noting that a number of earlier reviews commented that it wasn't); just slightly tart, but that is not the point as the tartness is a complement not the thing itself

Thanks, ta_hagen, for the opportunity

look: 3.75 | smell: 3.5 | taste: 2.5 | feel: 3.75 | overall: 3

Pours a clear gold with an ample head of foam that shrinks to near nothing rather quickly.

The nose is good. Typical Saison characteristics that I'd expect from it. Horse blanket, some of the usual spices, only a hint of any sourness.

The taste starts off good. Spice, horse blanket, slightly sour. Then a chemical slash medicinal flavour moves in that's very band aid like. Totally distracting and it ruins the beer for me.

Good mouthfeel.

This could have been awesome, I think. Ended up being on the low end of my rating scale for the style.

I think this beer would be better if I aged it for a few years. 2015 reserve, I think it's got a little youth to it that needs to age. Overall not bad, but I bet this will be so much better in 1.5-2 years. Pours typical golden yellow saison color, nice white head that reduces to a tiny white fizz after a few moments. Smells nice, a little bit of lactic sour smell at the beginning, grains, small hop character, fruity, and leather. Taste is mainly the first saison they used in this blend, consisting of tons of German grains. This beer has tons of lager flavor! You really taste the German wheat and Munich malt. Slight acidic taste but this guy is just a little too young, and fruity flavor (mango, peach, pineapple, guava, they really weren't kidding in the description!) Mouthfeel is nice and light, medium to high carbonation. Overall, not bad, just needs to age more. Kind of a let down with all the tags and ribbons stuck on the bottle, but I think I'll buy another and let it sit for a while.

2015 vintage. May release.

Pours a murky golden-orange with a foamy orange-tan head that settles to a partial film on top of the beer. Foamy streaks of lace form around the glass on the drink down. Tiny particles of sediment are seen floating around in the beer after the pour. Smell is sour with grain, citrus fruit, tropical fruit, chalk, funk, and acidic aromas. Taste is much the same with slightly sour grain, earth, fruit, wood, funk, and slight chlorine 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 mouthfeel. Overall, this is a pretty good beer with great sour citrus and tropical aromas, but the slight chlorine flavor detracts from the drinkability for me.

Serving type: bottle.

Served in a snifter from a 750.

Beautiful golden body with perfect clarity. Thick frothy pale white head, stays awhile. Lace develops as the head recedes. Carbonation shows. 5

Smells of brett, tart apple, white grapes, and wheaty saison aroma. 4

Bright, prominent brett flavors that impart floral notes, white grapes, white wine, and zesty lemon peel. There's a bit of harshness to the flavor but it's tasty. Sweet malty flavors went unperceived but show up at the finish. 3.75

Tart, a tad chalky, floral, vinous, and dry. The brett has a bittering effect that is a bit overdone but otherwise drinks very well. 3.75

750ml brown bottle, sample from the brewery.

Good looking head, left some lacing on the glass. Filtered clarity leaves no mysteries. Big time funk in the nose, clean and finished funk at that ... very aromatic with hints of tropical fruit, bandaids, and aloe. Solid crispness and just dry enough. Brett funk is very noticeable and seems to be the dominant force for the most part. Mild tartness in the back refreshes the palate with each sip. Peppery, citric, medicinal, earthy, and grainy in the slowly drying finish. Cheers to the brewers for putting this one together.

750mL (2015) into a tulip. Pours a hazy golden color w/ a frothy white head.

Aroma is grassy and vinous; green apples and pears, white wine, oak. Delicate and crisp.

Taste is slightly tart, vinous, just a little grainy. Subtle but complex. Saison spice. Citrus acidity. White grapes, pale malt, floral Old World hops. Grassy, earthy, a little funky.

Mouthfeel is crisp and light, refreshing.

Overall a really nice, well-built saison from a brewery I'd never heard of before.

It had a surprising better taste then I expected, but the beer didn't finish right. A good take at a sour saison, but this beer was completely forgettable.

so cool they fermented this fantastic base saison with a bunch of different yeasts and blended the beers together. its complex and gorgeous beer, with a belgian saison strain, a brett strain, and a lacto parent as well. golden orangey and not real hazy as the style goes. the head is tall and lasting in my teku, pure white and very attractive. the high levels of carbonation are quite obvious from the appearance as well. the smell is brett dominant, you still get the wheaty saison as the heart, but the brett contributes the most in the nose. its dry and farmy, but not super tart, and the malt freshness is apparent. the flavor is where the other yeasts influence the beer. the lacto blended bit is maybe less than a third of the beer, as its calculated and subtle, not a sour beer for sours sake, not highly acidic but instead approachable and gentle. citrus from the yeast and grassy hops marry well, and the carbonation drives it. the brett is funky and wet and weird, doughy and also a nice companion to this wheat malt. the idea of fermenting them in isolation and blending the finished beers is awesome because it allows the yeasts to be fully developed. you dont get them competing and working at different rates, you get the mature expression of all three, and thats awesome. loved this beer, fairly priced and delicious. have always been a fan of these guys and its great to see some new beers hitting.

edit: this ages really nicely too, dries out and carbonated up expertly, without getting a whole lot funkier. this is far better beer than its getting credit for being. great use of brett. 2015 vintage is drinking great right now!

Purchased at the General Store in the Grand Tetons National Park. 2015 edition.

A: bright golden with slights orange tinge on the pour. Less than a centimeter of head on a pretty aggressive pour, which disappeared after less than 10 seconds.

S: Acidic lemon and pineapple tartness meets brettanomyces funk and peachiness. Barnyard and slight stinky cheese, with an additive supporting slight presence of peppery phenols.

T: Orange and citrus on the initial sip, with Brett tartness meshing fairly well. Could certainly use some age on this, like the label suggests. The taste proceeds on to pepper and hints of other spices, with a strong light malt backing. The lasting aftertaste is more pepper spiciness and peach/mango tartness. All of the flavors are good, but as I mentioned, could use some time to mesh.

M: nice, champagne-like carbonation...which is semi surprising, given the initial pour appearance. Feels like a saison should!

O: all of the three distinct mix elements are quite good, but they're not seeing eye to eye just quite yet. I wish I could bring some home and cellar it for a few years!

Big ole 750... Too much. Pours clear dark golden with a fizzy white head.. Plasticky phenols with stewed fruits.. tart and sorta antiseptic on the finish.. lingering spicy clove/pepper notes.. Grassy and earthy.. Quite a trainwreck right now.. Medium/light body with not quite enough carbonation... oak grows with warmth... Funky and weird when fresh... I "might" buy another couple bottles to lose for a few years just to see what materializes, but right now, this is entirely too much and not very appetizing.

Typical hazy pale yellow color. Grainy aroma with a light spicy yeast scent. Same flavor profile with a nice funky sourness. Light, smooth body. Good drinkability. Pretty nice brew, worth a shot if you see it.

Served On-Tap

A — Pours a light and slightly hazy pale yellow color. There is a puffy light white colored head on it, some light lacing left behind.

T — Tastes clean and bright, lots of lemon, lime, tartness, bright barnyard and hay, grassy, funky.

M — Light-Medium bodied, bit of a lingering finish.

O — Great overall, and completely unexpected. Very very good.

Funky... Needs some age and the sour could come out... But very good Saison... I could drink these till the next morning and the next... Pepper, dry, sour, tart, banana, tart, apricot and farmhouse funky... It says decades to age and I agree, would love the sour to flourish in this and make a good beer. But, just grabbed another to age and worth the try, since this is REALLY, EXTREMELY GOOD for sure.

Poured on tap at Sour Sunday beer festival in Berkeley, CA. Brewers notes states that this is the Grand Saison brewed with brettanomyces.

Pours a typical Saison orange-amber with a large head. Upon first sip one recognizes typical saison flavors of wild yeasts and spices with a fruity zest. The mouthfeel is delicate and enjoyable and has very delicate carbonation. What makes this beer special is the artful craftsmanship of the sourness, which is subtly sensed as a secondary flavor to the beer. This beer demonstrates skill from the brewers at Grand Teton and is a delightful fusion of styles. I hope to see this one again soon.
