A while back Tirol teamed up with the famous Hokkaido chocolate manufacturer Royce to make a premium Tirol (which is a little larger than the regular size).
It sold out very quickly but I managed to buy some pieces online. Unfortunately because it contained Nama cream, most online stores would not send it overseas. Mine was sent during summer and leaked inside my parcel, and the Tirol ended up mutilated, but still edible - however I didn't take photos of the disaster so the above image is the result of a Google image search.
The chocolate itself was quite dark so it seems it had a rather high cocoa content. Inside it was soft and kind of chewy. Because of the Nama cream the chocolate was creamy and had a very milky taste. Even when melted, this Tirol was everything I expected it to be and was a really good representation of Royce. It's just a shame I only had 9 pieces because I could have easily eaten double that!
I hope that like some of the other Tirol releases this will make a comeback in the future! :)
