It had been two decades since Scotland last won away in Wales, and while they needed a missed conversion to edge home 20-18 in Cardiff, this was thoroughly deserved.
Since finishing last year’s campaign with wins over Italy and Ireland, the Scots have been riding a wave, winning WXV 2 and making huge strides under head coach Bryan Easson.
What is so exciting about the side is the depth being developed, particularly in the backline. Chloe Rollie has been a star since making her debut back in 2015, but it is a sign of how far the team has come that she was only on the bench for this one.
Emma Orr and Meryl Smith, 20 and 22 respectively, were sensational, while Coreen Grant was deservedly named Player of the Match as she wreaked havoc down the left wing, including scoring the opening try.
She is still only 26, while Scotland were without one of their rising stars, winger Francesca McGhie.
When you have so many players capable of beating their opposite number one-on-one, it opens up the possibilities in attack.
That Scotland led just 10-6 at the break will have been a frustration, such was their dominance in the opening half-hour.
But Easson is right when he says that his side were worthy winners against a very good Welsh team.
He said: "In the first half, we didn't take the chances we had but we spoke at half-time about squeezing more out of ourselves and we did in the second half. We deserved that victory.
"In the second half, we managed that particularly well. Seven wins in a row is phenomenal, this is a special group.
"We've had some tough times but we knew something was coming. There's still a lot to work on but we'll just keep growing."
Making it eight wins will not be easy. France laid down a marker earlier in the day with a 38-17 win over Ireland, monopolising possession and territory for much of the game.
Les Bleues are unbeaten against Scotland since 2010, with one solitary draw since then, while they ran out 55-0 winners in Vannes a year ago.
But that was a Scotland team short of confidence and trying to find their feet. This will be an entirely different proposition. And as Helen Nelson, whose late penalty proved decisive, explained, Scotland have their X-factor in the shape of outside centre Orr – whose arcing run set up Rhona Lloyd’s second-half try.
"When you have a secret weapon like Emma Orr, we know we can put the ball in her hands and she can put people away,” said Nelson, the oldest member of the backline at 29.
“Then the pace of Coreen and Rhona is a real strength of ours. Credit to Wales, it felt like we were attacking against a brick wall at times, but we will need to be a bit more clinical against a team like France next week."
Nelson is right that Scotland need to be more clinical, but this was a great platform upon which to build.
