The 19-year-old was a revelation in his debut season and appeared more like a veteran than a rookie, standing up on multiple occasions with clutch goals and physical play.
But Wines told AFL.com.au his butterflies weren't easing at all – not that it was a bad thing.
He said Power assistant Phil Walsh had helped him embrace his nerves rather than let them get the better of him.
"I actually get pretty anxious at the start of games – I think it shows how much it means to me, how much I want to do the right thing and play well," Wines said.
"I've been talking about it to Phil Walsh, our midfield coach, and he said maybe that's my thing, maybe if I went out there relaxed I might not be on.
"Slowly I think it will probably relieve itself a bit, but I think anxiousness is good nerves and good, positive energy.
"After the first bounce I'm right, once you get a bit of body on."
The big-bodied midfielder, nicknamed 'Quadzilla' by teammates, re-signed with the Power last Friday, tying himself to the club for a further two years until at least the end of 2016.
He said the idea of leaving Adelaide and returning home across the border wasn't one he entertained.
"The temptation of moving back to Victoria wasn't as much of an issue for me as the media made it out. I'm pretty happy here; it's such a good, family-based club," he said.
"I'm really enjoying it here and honestly I think we've got a really bright future going into the years ahead.
"My family's embraced the club. The club's been unbelievable in embracing my family and I think that's one of the biggest things here for me is how well they treat families."
Wines said he entered season 2014 with increased confidence in his physical ability to survive AFL matches after significantly increasing his pre-season workload.
After being drafted by the Power with pick No. 7 at the 2012 NAB AFL Draft, he was helped through his first summer and completed around three quarters of the work expected of the club's established players.
This pre-season Wines slogged his way through every drill set out for the playing group by high performance manager Darren Burgess and predicted it would help him lift in crucial moments this year.
"I've been working hard on my fitness base, having come off 70-75 per cent last year, to this year I haven't missed a session," he said.
"Not just the physical side of fitness but mentally now I know I've done the work and that will be in the back of my mind in the last quarters of games.
"The good thing about having Darren Burgess is that he knows everything, he's managed me to a 'T' and the body's feeling perfect – I'm really fit going into the season."
