The visitors - who have set themselves up for a chance to clinch the title on their home patch against Ireland next weekend - were totally in control by half-time.
Central to that superiority was scrum-half Peel, but he paid tribute to the efforts of his Wales pack as well as his fellow backs in a performance which yielded Wales six tries to Scotland's three.
"We knew it was going to be a very tough game up here," the half-back told BBC2.
"We came out all guns blazing, and I think played some of our best rugby of the tournament in the first half.
"The pack were awesome and gave the backs the platform to launch their attacks."
