Good balance of roast and sweetness, very good, but in today's panorama this beer is not the highlight anymore.

2020-03-30, vintage 2017, 13.2% ABV, 8-4-8-4-16=40
Lean, balanced, with chocolate flavour, touch of liquorice, moderate sweetness, and not really much bourbon.

2019-02-12, vintage 2019, 10.3% ABV, at The Gull, 7-4-7-3-15=36
Dark brown colour, near black. Notes of cardboard in the aroma. The mouthfeel is a bit thinner than I remember from previous vintages. The main character comes from the roasted malt; little sweetness; no barrel notes; it mellows out as it gets warmer, but still can't achieve greatness.
Good beer, but I'm a bit disappointed by the decline.

2017-11-25, vintage 2017, 13.2% ABV, 8-5-8-4-17=42
Initially the liquorice notes are stronger, later the chocolate is more evident, and even a note of espresso. In the final, some bourbon. Pungent, excellent.

2017-03-24, vintage 2017, 13.2% ABV, 8-5-8-4-17=42
Such young sample is characterized by the power of the roasted malts, coffee, lean body, off-dry mouthfeel, and moderate bourbon.
Excellent.

The age has mellowed out this brew, has softened the edges, without weakening any trait; sweet dark chocolate with bourbon, leather and tobacco. Warming alcohol.
Wonderful.

2013-11-15, Winter 2012/2013, vintage 2013, one year old, 8-4-8-4-17=41
Pitch black color, small head. Strong aroma of roasted malt, whiskey barrel, raisins, light vanilla, some alcohol, tobacco, leather; complex. Thick and heavy body; round mouthfeel; it has a strong flavor of roasted malt and chocolate; the vanilla and Bourbon is very strong too; it has some liquorice and leather; medium to strong bitterness, with sharp alcohol presence, yet not boozy.
Very interesting.

Vintage 2012
Black colour, red hue, beige head. Aroma of cacao, caramel, roasted malts, vanilla, chocolate, lots of cacao. Sweet flavour, light sour touch, cacao, chocolate milk. Full body, quite warm, alcoholic finish, lingering chocolate. Not really getting the Bourbon notes (personally I just get a hint of vanilla), but a more than nice beer nonetheless!

Bottle @ ZZT8:BBT1. Pitch black, small brown head. Smells chocolate, sweet, muffin.. Amazing. Tastes liquorice, sweet, chocolate, roasty, coffee, ash. Full body, silky, soft carbo.

Pretty well done. My major mistake was drinking this after an expedition stout, but it still holds up pretty well. Initial malt smell a tiny bit off like a few Ontario I-stouts I’ve had recently. The bourbon is pretty evident here, with some booze, dark chocolate and roasted malt. Finishes all bourbon with some boozy sweetness. Pours black with good mocha head and lacing. Texture creamy and slick. Has a little spice in the end as well. 2013 bottle.

Bomber from Malt & Vine. Pours very dark brown with a creamy/bubbly tan head. Aroma is pretty much bourbon. Near full bodied. Flavor starts with chocolate and quickly transitions to bourbon. The funny thing is that the bourbon is not overpowering - it’s just the principal flavor in a very smooth and tasty IS. There’s burnt malt, but the bourbon smooths it out. The heat is hard to find. Finishes mildly sweet chocolate with bourbon. Oak? I think so. There’s an astringent aspect. Really good stuff here.
