On their last trip to this venue three years ago, the Saltires conceded a painful 403-3 to a rampant Somerset batting line-up in a competition then contested over 50 overs.
Stander conceded 106 runs from 10 overs while Marcus Trescothick and James Hildreth mercilessly laid into some ragged Scottish bowling.
It remains the biggest total leaked by Scotland in a 50-over match, while Stander's is the third most expensive 10-over stint in county cricket.
Yet if there is any fear in the current Saltires squad, it is hard to detect, and it certainly isn't present in the Stoneywood-Dyce all-rounder.
The Stander story is an intriguing one because, while he hasn't played against county opposition since 2009, he is the only survivor from the side so comprehensively taken apart.
"The last game at Taunton was an interesting experience," recalls Stander wryly. "The ground is different from any other venue because basically the whole playing area is just like a big square and anything short or off line just goes.
"You also have to worry about the boundaries because the shortest ones are the straight ones so batsmen can just play through the line and send the ball sailing back over your head."
Former England Test hero Trescothick and Hildreth did that, scoring 144 and 151 respectively while compiling a county-record second-wicket stand of 260.
Yet it was the explosive late hitting of Peter Trego who blasted 74no from 39 balls that left a lasting impression on Stander.
"Trego really did the damage near the end after the platform had been set and basically his knock put them out of sight."
In the last two years Stander has been seen largely as a T20 specialist and his aggressive batting suits the game's shortest format, as shown by an astonishing 116no during last autumn's series victory in Namibia.
However, the South African-born player is delighted to have the chance to show what he has to offer in a 40-over contest and is keen to impress in all formats.
"I've been given a particular role in T20 cricket which I enjoy but I've missed playing against the counties in the last two seasons. Now it's great to get the chance again and I was also in the squad for the [abandoned] I-Cup game against Canada last week. I like playing in all formats and am doing everything possible to get myself firmly established."
Will he be happy, though, if stand-in captain Preston Mommsen asks him to bowl at the free-scoring Somerset batsmen today?
"I'm looking forward to the challenge," he says. "Although I've reached 30 and some people might think I'm tailing off a bit I actually believe I'm bowling better and faster than at any time in my career.
"I've worked hard on things and I think I have a more mature and relaxed outlook to the game now.
"I think because I'm so passionate about playing for Scotland I maybe tried too hard in the past, but now I'm able to accept tough situations and deal with them.
"Sometimes you need to learn the hard way and I learned a hard lesson that day at Taunton."
Hopefully Stander will reap the rewards this afternoon as the Saltires aim for their second victory in a stop-start campaign.
Coach Pete Steindl's men are buoyed by their World Cricket League victory over Canada in midweek but they are still short of top-flight action
Steindl admitted: "You could maybe see we weren't completely match sharp but getting the Canada game on and winning it was exactly what we needed."
