Notes: Live long and drink Cosmic Ristretto. This highly revered brew will go down in history as one of the first graduates of our Genius Lab program into our front line. Marvel at its rich black appearance with bruleed edges and mocha-colored beer foam. Breathe in its coffee aroma and sweet malts, and savor its smooth, espresso, chocolate flavor. Don’t fight its gravitational pull. This bold, complex, java-centric Baltic Porter with Espresso is irresistible. Houston, we have a problem, my glass is empty.

look: 4.25 | smell: 4.25 | taste: 4 | feel: 3.75 | overall: 4

Poured from 22oz bottle into a tulip.

Appearance: rich, dark color, evocative of brown but basically black. Head is a finger of frothy dark-tan foam; its appearance is really wonderful.

Smell: malty and slightly sweet with a really lovely roasty, coffee flavor, accentuated by a little bit off toffee. The coffee element really complements the roastiness of the dark malt; it doesn't feel overwhelming or "green". I really like it.

Taste: lots of malt, toffee and coffee here; the flavor has a little bit of that "green" element, which I can only describe as a bit of a vegetal hop character that I get in some dark beers, which also reinforces a rawer characteristics of the coffee. That is more of a nitpick in an otherwise very tasty beer.

Mouthfeel: medium body with a moderate carbonation and creaminess. Based on the big malt and sweet character, I would expect a bit more body and creaminess from this guy.

Overall: mouthfeel notwithstanding, this is a very tasty beer that I would love to drink at breakfast while camping. Move over, coffee stout -- Cosmic Ristretto is in town!

This was poured into an English pint glass. The appearance was a dark brown close to black color with a thin white to off white foamy thin head. Semi-thin foamy lacing glosses around the sides of the glass nicely. The smell had a rich dark espresso to milky chocolate/semi-sweet cocoa bean but also somewhat burnt coffee bean. Decent roast. The taste tried to follow through on the wanted flavor. Mainly had that roasty to burnt flavor rolling on into the aftertaste. Slight dry/roasty/burnt finish. On the palate, this one sat about a medium on the body with the burnt/roasty/espresso sort of feel hitting my tongue decently. Hmmm...there’s a part of me that wants to say "excessively," hmmm...not bad. Overall, for a Baltic Porter, pretty good for the most part, leans a bit more towards the roasty sort of almost burnt coffee bean-esque thing.

Poured a jet-black color with a small, tan head of bubbly foam. It smelled of coffee and dark chocolate. Good roasted malt flavor with a coffee bite. Some dark chocolate and sweet toffee, too.

look: 4.25 | smell: 3.75 | taste: 3.75 | feel: 4 | overall: 3.75

L: Poured from a bottle to a pint glass. Had a dark brown / black color and a thick consistency. There was an inch of foamy head that lasted an average amount of time. Very good lacing.

S: A decent, but not exceptional aroma of coffee, chocolate and malt.

T: Tasted of a lot of dark chocolate, some light vanilla notes, a good shot of coffee (more like espresso), lots of roasted malt, a definite creaminess, and a grainy quality. An interesting flavor that seems more subdued than it should be. A beer with espresso should be more aggressive than this. Still, it's decently tasty.

F: A nice amount of carbonation with a smooth finish. medium-bodied.

O: This is very much an uneven beer. Green Flash has made better beers. Nonetheless, it was worth trying.

Draft at Scofflaw, part of a Green Flash tap takeover.

Brownish black body with ample foam, spotty lacing around the edges of the glass.
Aroma is rich and coffee forward, espresso brings the intense roast.
Taste is similarly coffee forward, with a smooth black malt base. Moderate intensity of coffee flavors, not too bitter.
Feel is light, creamy and smooth with no twang or astringency. Nicely blended, would get this again.

4.49/5  rDev +9.8%
look: 4.25 | smell: 4.5 | taste: 4.5 | feel: 4.5 | overall: 4.5

Poured into a 16 oz snifter at near room temperature best before 4/7/17. Pours a very dark brown with a two plus finger light tan head that leaves plenty of streaks of lace.

Smell is coffee beans, vanilla beans, biscuit, baker's chocolate, and a hint of Ameretto.

Taste follows bold expresso, vanilla bean, chocolate, biscuity grain, and like those chocolate filled Ameretto candy you get at Christmas.

Mouthfeel is bigger than medium, kind of creamy, moderate amount of life, not really dry, and excellent drinkability.

Overall this is very one dimensional, but it isn't a bad thing at all, because it is really tasty.

Poured from a bomber into a tulip

L: Pours a dark black pour... a bit of mahogany brown at the edges. Thick creamy tannish head. Fantastic lacing and retention.

S: Creamy cappuccino and roast espresso. Loads of coffee.

T/F: Definitely a coffee porter... roasted grains and smooth espresso. Malt sweetness and cocoa. Feel is thick and creamy. Good carbonation... mildly bitter roast at the finish. Warming... the ABV is hidden and sneaky.

O: A delicious coffee-themed roast porter. Not nearly as bitter as I was expecting, and a very creamy cappuccino style texture. This could almost be a breakfast beer if not for the ABV. Well played Green Flash.

3.62/5  rDev -11.5%
look: 4.25 | smell: 3.5 | taste: 3.5 | feel: 4.25 | overall: 3.5

Very nice mocha head, good size and retention, and lots of lacing.

Aroma is slightly metallic, bringing notes of soured fruit and grapes to go with the expected burnt coffee and cacao notes. A little bit of vanilla and cream; robust and roasty. Nothing on the nose you can't get from other stouts, nor quite as polished.

First impression as the brew hits the palate is quite positive: notes of coffee and cacao. The excitement quickly fades, however, as first third - and the middle - quickly give way to a muddled mix of stout flavors. Roasted barley, tobacco, sour dark fruit, char. Nutty, roasty, slightly ashy finish.

Mouthfeel is smooth: fairly thick, especially for a Baltic porter, but drinkable and smooth as expected for the style. Fairly long finish, carrying a touch of alcohol heat.

Really, there's very little coffee in this; if someone told me this was a standard porter, I wouldn't know it's supposed to be espresso-infused. That's not to say it's bad; it's just nothing special for me.

22 oz bottle served cold into a tulip. Marginally past it's best before date, we will see how it holds up.

Appearance - Ominous roan color from the bottle that turns nearly black by the time it hits the glass. A small half finger of soapy tan head is poured and lingers. Some small curtains of lacing left around the edges of the glass.

Smell - Loads of rich coffee aroma here, smells freshly ground and brewed. A sweetness in the background that is reminiscent of mocha. A twinge of vanilla in the background but coffee first and second, front and centre.

Taste - Damn that's smooth. Lots of coffee up front, fresh Sumatran blend or something but there's a subtle brown sugar and even cinnamon sweetness right in behind that gives the taste of a very expensive and well made flavored coffee. Maybe it's marshmallows too. Some bitter hops on the close.

Mouthfeel - Velvety smooth and actually reminds me of FBS in its super smooth delivery. Some heat at the back of the throat for the alcohol burn but creamy and a delightful sipper.

Overall - One of the best on the market, super smooth and creamy with a big coffee focus, but the subtle cinnamon, brown sugar and marshmallows elevate Ristretto Baltic Porter with Espresso to another level. Certainly worth a try and a little extra aging hasn't hurt this one.

First had poured from 22-oz. bomber into tulip. Surprisingly, the espresso addition to this Baltic Porter does not detract from but rather reinforces the characteristics of the style.

Dated as bottled 7/2015. Beautiful appearance; coffee and slight alcohol in it's aroma; Medium body and creamy mouth-feel; the taste has slight coffee, when colder it has a metallic tang in the finish that seems to lessen when it warms.

Tastes similar to what I remember a Baltic porter tasting like: a little more hoppy and bitter than an American porter. I hope to get more and see if after another year the metallic tang goes away (as it is supposed to do with old ales).

Exceptional Porter!!! Pours a dense dark brown color, some reddish highlights comes through when held to a light. Big antique white head with excellent retention. Lacing is mostly a thick tan film. Really robust aroma. Big malt aroma followed by rich espresso coffee. Flavor is just as strong. Strong malt presence up front, followed by some sweetness, making the beer seem like a milk stout. Then the espresso kicks in. The finish is coffee bitterness. Mouthfeel is rich and smooth for the most part. The candi sugar sweetness then the finishing bitterness add some complexity. In all, a very impressive brew.

As of this review this beer is on tap at Green Flash Brewery in Mira Mesa. It has a very dark and heavy flavor to it, and every pint has a shot of espresso in it. There was a noticeable roastiness to it as a result of the espresso. I really wanted to try it side by side with their Double Stout for comparison, but unfortunately that beer was discontinued about a week ago and who knows when it will come back. I remember the Double stout having a more chocolaty, bittersweet flavor that this beer didn't really have. Either way, this coffee brewed porter is pretty great!

This beer is really great! The smell doesn't do it service, but once it hits your mouth you get hit with delicious coffee, and then on the tail end a bit of malt. It has a very light mouth feel and isn't syrupy like some coffee brews can get. The carbonation is very refreshing and overall it is a very tasty brew! I would definitely buy again.

On tap at Yardhouse Rancho Cucamonga on 07/24/16.

Opaque black with a half-inch tan head that remains as a cap on top and leaves thick strands of lace. The smell is of strong dark roast coffee with chocolate syrup and light cream. The taste follows with a flavor profile that is reminiscent of a creamy cafe mocha. I was pleasantly surprised by this one.

22 ounce bottle into snifter, best before 8/25/2016. Pours nearly opaque dark brown/black color with a 1-2 finger fairly dense and fluffy tan head with good retention, that reduces to a thin cap that lingers. Nice spotty soapy lacing clings around the glass, with a fair amount of streaming carbonation retaining the cap. Aromas of big nutty dark roasted coffee, dark chocolate, cocoa, caramel, brown sugar, and toasted dark bread; with lighter notes of raisin, plum, currant, vanilla, smoke, char, herbal, wood, and roast/toasted earthiness. Damn nice aromas with great balance and complexity of dark/roast/bready malt, coffee, and light-moderate fruity yeast/earthy hop notes; with great strength. Taste of big nutty dark roasted coffee, dark chocolate, cocoa, caramel, brown sugar, and toasted dark bread; with lighter notes of raisin, plum, currant, vanilla, smoke, char, herbal, wood, and roast/toasted earthiness. Moderate roast and herbal hop bitterness on the finish; with lingering notes of coffee, dark chocolate, cocoa, caramel, brown sugar, toasted dark bread, herbal, wood, and roast/toasted earthiness on the finish for a while. Fantastic complexity, robustness, and balance of dark/roast/bready malt, coffee, and light-moderate fruity yeast/earthy hop flavors; with a great roast/hop bitter/sweet balance and zero cloying flavors after the finish. Light dryness from hop/roast bitterness as well. Medium carbonation and medium-full body; with a very smooth, creamy, and fairly sticky/chalky balanced mouthfeel that is great. Alcohol is very well hidden with minimal warming present after the finish. Overall this is an outstanding Baltic porter! All around awesome complexity, robustness, and balance of dark/roast/bready malt, coffee, and light-moderate fruity yeast/earthy hop flavors; very smooth and easy to drink for the ABV. A highly enjoyable offering.

L: Pours opaque dark brown to black under a moderately persistent 1” cream to light tan foam stand.

S: Big espresso aromas with some roast malt.

T: Roasty with a trace of prune. Malt roast flavors lead the attack with espresso roast becoming more prominent from mid palate to the finish. The Baltic porter flavors are clean and moderate with a trace of sweetness to provide balance and support for the espresso.
F: Very creamy, smooth, full body, medium low carbonation.

O: A very delightful drink that suggests a lightly carbonated espresso lightly sweetened by malt.

22oz bottle purchased at Enoteca in Post Falls, ID, for $8.99. I’m fully prepared for this to be bad. I dropped the bottle as I stumbled in after a night of much beer buying and beer drinking and dropped it. The bottle survived the fall, but a certain amount of foam came spraying out under the cap onto the floor. Been a while since I’ve had a Baltic Porter or a beer from Green Flash, so I had high hopes for it. According to the label, this is best by August 26, 2016.

Poured into a Mass Transit Ale pint glass (thanks, Connie, wherever you are!), at first glance this was a black-looking shade of brown with a sudsy tan head (glad to see it could still inspire some carbonation after the mishap noted above.

Sweet and roasty coffee nose to this at first. As it warms, some more bitter, hoppy notes come out to play.

Sweet, chocolaty coffee notes hit the taste buds first. They’re backed up by some bitter hoppy notes and a more coffeeish roasty bitterness. The finish runs back to sweetness, with some brown sugary notes. The finish is moderately clean for such a sweet beer, which makes me think they used a lager yeast for it (there’s no confirmation of this on the label, but it’s certainly not unknown with Baltic Porters).

Mouthfeel is creamy, yet finishes fairly clean for a big, sweet coffee beer.

This survived being dropped and having emitted some beer as foam rather well. I don’t think I’d put this in the front rank of Baltic Porters I have known, but it was quite tasty. It would probably be best experienced as a dessert beer, which is sort of how I’m drinking it now.

Tasting notes from May 25th, 2016. Had on-tap at Alley Katz in Citrus Heights, CA

Appearance - Served into a pint with a khaki, quarter finger width head, the brew is deep, dark cola brown with a thin, broken layer of suds across the top. Lacing is fair, with broken webbing making up the bulk of it.

Smell - Coffee roast, with underlying notes of caramel and chocolate.

Taste - Follows the nose. Coffee roast and lesser chocolate, while hints of caramel and cream come into play. Faint earthiness and moderate grassy bitterness start to cut through as the beer warms. Finishes with a fair balance of roasted character and sweetness.

Mouthfeel - Light to medium in body with light, tingly carbonation. Silky, almost creamy texture. Uniquely refreshing with a semi-dry finish.

Overall - Great Baltic. full flavored, but light enough to be enjoyed on even the hottest of days. One to keep an eye out for in the future.

Newest WOW brew from Green Flash I have tried. This fine porter pours from the bomber into
the snifter a deep dark mahogany with a decent head of light tan foam that subsides to a thick
ring, thin pool, and subtle lacing. Nose of espresso, char, fudge, and deeply roasted malts.
Flavors follow the nose with espresso on the front and sides, fudge notes hit nicely on the middle
to back of the taste, and mingle with deeply roasted malts and medium to heavy char on the back
finishing with a bitter malt flavor and a touch of herbal hops. Nice mouth feel, creamy on the front
and fading into mild carbonation. Overall this is an excellent porter in the "Baltic" style.

22oz bottle served in a large snifter. Best by 25 August 2016.

Pours black with a smallish light brown head and lots of carbonation. Smell is coffee and a hint of yeast.

Taste is coffee, with a hint of dark fruits, maybe some cherry.

Mouthfeel is thick, rich, and effervescent. Overall, it's good, but certainly not legendary.

This beer poured black in color with a tiny tan head.
Intense coffee aroma, then a little chocolate.
Coffee taste first, kind of a dark roast. Cocoa and bittersweet chocolate later.
Lighter bodied than I had anticipated,
