Bottle to snifter.

Maple, almond, very sweet. Super tasty at first, sweetness gets a little cloying after a while.

Thick and Sticky.

**

500 ml bottle

pours inky black, with dark brown colored head that fades. rich aroma of dark chocolate fudge, espresso, a little maple and nutty too. so I get all the components. taste is complex as well, but just too sweet for me. thick, full bodied, smooth feel.

I think they went a tad overboard with the maple syrup. This stout is really good but it’s so sweet it makes this beer a slow sipper. I wish there were more balance between the chocolate coffee and syrup. Very rich and sweet.

Poured from a 500ml undated bottle to a snifter at 58F.
The body is opaque black and there is minimal foam, but tilting the glass shows a brown foam. The liquid itself coats the glass with like 5W10, quite impressive.
Sniffing brings alcohol and almonds.
Most things on the label come through in the taste. There is almond and coffee. The maple really comes through at the end. Alcohol seems to be just about the 10% listed. Real truth in advertising here.
The body is phenomenally tongue coating and lip sticking.
This is a really good beer.

Bottle at share. Black, inky pour, ring of beige head. Aroma is chocoalte, nutty, coconut. Taste continues with more candy bar goodness, notes of maple added, smooth, slick, delicious.

 

 

 

Had on tap at Mortalis; then again … now from bottle from same release about a year later.
Mortalis just keeps putting out rich, smooth and complex Imp stouts that are so in my wheelhouse.
Kicking back outside on a perfect evening. Jerry Jeff “Live from Greune Hall” playing …a good cigar… sipping the brew. Perfect!
Dark brew with auburn accents to setting sun. Decent creamy head that shifts to halo then disappears.
Subdued nose of that showcases macadamia and almonds in midst of deep background of coffee and cacao-chocolate.
Taste explodes with above but really brings out the maple. The cacao is more forward blended with nuttiness. Thankfully no needless sweetness.
Body is thick/heavy at first, but relaxes as beer breathes and warms. Now thinner and velvety and increasingly enjoyable. Some bright carbonation tingle shows early…but becomes less noticeable as beer airs out. Well hidden abv. Brew that feels more like an enjoyable after dinner port or Madeira would feel.
Overall a really nice full bodied stout that keeps evolving its taste from pour to finish.
Well done!

From a 500ml bottle, undated as best I can tell. Purchased at the brewery 12/17/22 and merrily muled across successive state lines by @franktank18. Served in a tulip.

Pours a syrupy black with warm caramel highlights around the margins. No head formation, neither cap nor collar, just a thin, oily film when I unsuccessfully attempt to rouse up a little lacing.

Nose is sweet and nutty with cocoa and warm, cinnamon-like spice. Triple-checking the label for ingredients and not finding cinnamon but I swear cinnamon is what I smell.

Taste is dense and intense, with thick, burnt sweetened coffee, nut fudge and super-earthy grade-maybe-D maple syrup. I’m getting some cinnamon heat, if not the actual cinnamon taste and an unfortunate, overpoweringly unpleasant camphor taste, right up into the sinuses. I think it must be the macadamia nut? but it’s coming through as camphor, or mothball, and overpowering everything else.

Feel is thick, sticky and syrupy with vanishingly gentle carbonation.

I cannot claim that I particularly enjoyed this. Somehow, to my palate, the macadamia, maybe in combination with the maple? came across all totally camphor/mothball-like and I could not convince my brain otherwise. Fwiw, mammosilenus didn’t think it tasted like mothballs; she thought it tasted like Bailey’s but, of course, she was wrong. For a few minutes there I thought she might finish it for me but, no, I had to pour the last little bit out.

Fun fact: cinnamon and camphor come from related trees! So although I may have been hallucinating, I was hallucinating consistently.

 

2021 500ml bottle poured hard, cellar temp to a tulip. Color is a dark, murky burnt sienna. Head is two-finger tan, creamy, tight-cell insulation on top, that hangs out longer than many of the stout heads. Nose is a bit of marshmallow, even though I don’t think there is any in the brew, with a hint of maple syrup and a whiff of coffee in the background. It reminds me of a diner breakfast of pancakes, syrup, and coffee. First sips bring in a lot of the Dominican cocoa nibs. I’ve been fortunate enough to have the DR cacao nib liqueur right from the source, and the Prometheus takes me back to the island! I think the dark maple conjures the liqueur taste, which is a nice harmony. I’m not getting a lot of nuttiness, which I thought would have been very prominent from the macadamia and almonds, but they could certainly be lending themselves to the full and creamy mouthfeel. Any coffee in here is very mild, like morning blend, but you get an aura on the nose and on the tongue. Alcohol hides entirely, as in, 500 ml might be gone before I finish writing this. If they’re stashing away this brew in barrels, I must get those...in 12-18 months! Their stouts are as thick as their sours, almost a purée of sorts, with sticky lacing that clings to the side forrrrrrrreeeeeeeeevvvvvvvvverrrrrrrr. I want to sip, but it is really best with a mouthful. Everything is very balanced, though some might find it too sweet. I would not classify this as a dessert stout, but make no mistake, it is decadent.

 

On tap at Mortalis Brewing Co in Avon, NY.

This one pours a very dark black color, with a small head, and not much lacing.

This smells like rich dark maple syrup, fresh bright roasted coffee, chocolate fudge, and just a hint of nuttiness. The coffee aroma is killer - it just leaps right out of the glass.

Mortalis coffee stouts always tend to be coffee heavy at release, so the coffee kind of drowns out the nuttiness. I get a bit more almond than macadamia, which is fairly faint. The maple stands up to the big roasty coffee, though. The maple is high quality and very dark. It's a pretty sweet beer, but the coffee roast does do a good job in balancing the sweetness out a bit.

This is thick and chewy, and a touch syrupy, with no booziness, and a surprisingly high level of drinkability for the ABV and style.

Mortalis does a lot of things well, but their stouts will always be the apex for me. They have it completely figured out at this point.
