When you touch the bottle with your hand the upper black layer will turn transparent to reveal the product information. This will happen only if the bottle has drinking temperature.

To signal the recommended drinking temperature we used color changing thermo pigments for our design. The warmth emanating from a hand is not strong enough to make the upper black layer transparent if the bottle is way too cold. Yet if its temperature is right, a warm hand is just enough to bridge the gap to the predefined “display“ temperature.

Turmhof was able to reinforce its excellent reputation as a boutique distillery and the limited edition became a collector’s item.
