Tasting notes by Serge Valentin (Whiskyfun.com): 94 points

Colour: gold (a shade deeper).

Nose: A tad straighter and more mineral than the 03 at first. But also more medicinal, more embrocations, bandages, gauze and various subtle ointments. The raw farmyard note in the 03 is displaced here by a balancing but deep sootiness. Give it time and the waxiness bubbles up to the surface like slow lava. In time the earthiness becomes gravelly and there’s this note of turmeric, capers in olive oil and some fresh, yeasty breads. With water: really a similar ‘unifying’ effect as in the 03 but again here it’s more sooty, more polished, more light green fruits, more beeswax and wee flickers of lanolin and lamp oils.

Mouth: you do notice the wee variations between them. This one is again leaner, straighter and more direct. It goes towards the peat in a more singular and precise fashion. But it’s brilliance is unquestionable. White hot peats, metal polish, more of this wonderful wood ember character, sandalwood, seashore salinity, paraffin wax, camphor and a texture that’s almost approaching old sweet wines such as a particularly excellent SGN - no wonder these are often considered ‘wine drinkers whiskies’. Will this anti-maltoporn brigade never get here...! With water: if you’ll excuse me but, holy shit! Water exposes the most stunning medical side in this one. Like pear eau de vie, mercurochrome and precious ointments all fused together. There’s damp hay, white truffle oil, smoked German beer, old ink and tiny tropical notes like pineapple syrup.

Finish: similarly endless, only here there’s the most sublime and muscular saltiness. Like a great tidal swipe of sea salt, lemon rind, tar, dried seaweed and smoked oyster sauce. In the aftertaste there’s a callback to these more rural, earthy, mechanical notes.

Comments: There isn’t much between them to be honest. Maybe I preferred the 03’s broadness and more overt farminess a tad more, but it’s splitting hairs really. Both are truly magnificent, humbling and beautiful whiskies.
