Penderyn managing director Stephen Davies commented: "Yet again, the Welsh national team has made us extremely proud. The fact that this is the third Grand Slam special edition we've released speaks volumes - the squad has done an incredible job and we've created a world class whisky to reflect this."
Neil Latimer, Retailing & Licensing Manager for the WRU, commented: "Winning one Grand Slam is a tremendous accolade, but winning three over the course of seven years is the mark of a special team. We're proud of the work we do as ambassadors of Wales, and it's great to see Penderyn following suit with the release of another world-class whisky."
Welsh star Adam Jones commented: "Winning the 2012 Grand Slam was a very special day for me, made all the more special by the fact that it's the third time that I'd won the honour as part of the Welsh team.
"It's great to have a unique bottling to commemorate the event - it'll have pride of place on my mantelpiece along with the two previous Penderyn Grand Slam Editions!"
