Calmix

Tap to rate

A touch of pepper and a little cocoa mark this Russian imperial stout from Martinus at 9 %, a heavy winter beer made with Naga Jolokia, which in 2007 still held the record as the world's hottest pepper. The name recalls the Calmix petroleum heaters of the firm that commissioned the brewery's building.

Tasting Notes

AI-generated sensory profile for Calmix

◎ Appearance

Deep mahogany to near-black in color, with an opacity that speaks to the beer's full body and roasted grain bill. A dense, tan head forms readily and clings to the glass with persistent lacing. Carbonation is moderate and measured, appropriate to the style's weight.

◌ Aroma

The nose opens with bold roasted malt—dark chocolate and espresso notes dominate—layered beneath with a distinctive peppery spice from the Naga Jolokia. Dark fruit esters add subtle plum and raisin complexity. A warming alcohol presence threads through, without harshness.

◐ Taste

Entry is full and creamy, with rich cocoa and roasted grain immediately apparent. Mid-palate brings the heat: a building peppery bite that lingers across the tongue without overwhelming the underlying sweetness. Coffee and molasses provide ballast, while the 65 IBU bitterness arrives late and clean, framing rather than dominating.

◑ Finish

The finish is long and warming, with peppery notes persisting on the palate and a gentle boozy warmth settling into the aftertaste. Residual sweetness and roasted grain linger pleasantly without cloying.

Serve at 13–16°C

Slightly warmer than you might expect. 10–13°C lets the roasted malt, chocolate and coffee notes open up fully.

Pint glass

The classic — versatile, comfortable to hold and keeps the beer cool. No frills, no distractions: just the beer.

Can be cellared 2–5 years. Develops dark fruit, leather and port-like complexity with age.
