Sadly, we think you're too late. There was a company out on Boulder Highway called, fittingly enough, Coffee Roasters of Las Vegas. Here's what we wrote about it in this column back in 2005 in answer to a question about free factory tours:
"Master Coffee Roaster and owner Rich Serpe was seduced by the world of coffee during a trip to Italy with his grandfather, more than 30 years ago. Since then he has not only established a renowned roastery in Las Vegas but has helped set up scores of roasteries and coffee shops all over the country. Today, they produce more than 45 different coffees, 40+ flavors, and 40 hand-blended loose-leaf teas on the premises, and have a policy of welcoming new and old customers alike as members of the family. Anyone is welcome to go along during business hours to witness the whole process of roasting, flavoring, blending, and packaging and to check out the retail area, which, in addition to the huge range of coffees and teas, also features chais, syrups, cocoas, biscotti, scone mixes, T-shirts, mugs, coffee and tea-making equipment, gift baskets, and bags and purses fabricated from recycled coffee bags.
"Hours of operation are 8 am-5 pm Monday through Friday and 11 am-3 pm Saturday. Small groups are charged $1 per head (a contribution toward the coffee/tea and cookies you’re served) for an informal tour of the roastery, while for groups of about 10 or more, organized tours are available at a cost of $4 per person."
We regret to inform you that this business shut down, somewhere between a year and two ago.
However, your question inspired us to dig deeper and we found another company called Green Valley Coffee Roasters located out on E. Patrick Lane, boasting the slogan "Fresh Roasted is the Difference." Granted, Henderson isn't Las Vegas, but under the circumstances we figured you wouldn't split hairs. But before you get your hopes up, a call to Dwight, the proprietor, revealed that he's no longer producing the beans commercially. Their website is still live, however, and has some interesting tidbits if you're interested in coffee terminology and the roasting process.
One last dig unearthed another Las Vegas company called Jitters, which seems to have three locations in town and a website selling beans. The first time we visited, it all appeared to be fully functioning, with a variety of different beans for sale. It looked promising, but the number for the first of the individual venues that we called turned out to be disconnected; the second got us through to a Jitters that is still apparently open at the Riviera (ironically, about the only thing that is still open at the Riv), but doesn't sell beans; and the third number connected us to a voicemail. So we left a message but heard nothing back and when we just checked out the website again, the link to their home page was broken and our email remains unanswered. Sorry, but it doesn't look good.
Even the locally produced Havana Honeys brand has apparently been bought out, while the Las Vegas Vodka site was "down for maintenance" (and didn't look like it was coming back up anytime soon), so Vegas' own cigars and Bloody Marys are off the breakfast menu, too. So, unless you want to start your day with a breakfast of authentic Sin City Brewing Company Las Vegas beer and a side of chocolate from Ethel M, it looks like you're out of luck with regard to Las Vegas-produced breakfast items.
