Someone else might be able to explain it in more detail than me, but it’s basically a retirement fund. You can select a certain amount from every paycheck to be put into your 401K. And I believe Starbucks will still match that amount too. For example when I worked at Starbucks, I selected to have 5% of my paycheck be put into my 401K and then Starbucks matched that dollar amount and also added it to my 401K. “Future Roast” is just the goofy name Starbucks gives their 401K

401k is a savings plan. You can choose to set a percentage it will pull out of your paycheck and put into your 401k. And that percentage is actually dropped in different type of stocks that Fidelity(the company Starbucks partners with) either chooses for you or lets you choose from a list of stocks. Depending on how the stocks do it can increase or decrease the amount you’re making. Starbucks matches up to 5%. So if you chose 5% as the amount to be pulled out of your paycheck, that money is protected and you will make that money every time. But Starbucks stocks are very good I’ve saved lots of money investing 15% of my paycheck into it. And all of that money goes into your 401k which is like a savings account. And you can pull from it anytime that you’d like, and if you get a new job your 401k savings will transfer to your new job.
