Hey been following your thread. My home town is in the Finger Lakes and I work in the Utica. I currently tend bar, I've served in pubs, worked dozens of beer tastings all over the finger lakes, and actually apprentice brewed at a competing brewery on the south side of town.
I've "toured" many of the bigger breweries in the aforementioned replies (and yes Sam Adams BLOWS, It wasn't an actual tour we were just herded around their show rooms, plus they selected the beers (3) all which I've had before) Pretty cheesy. So we went across town to Harpoon where we drank ourselves silly. I'd recommend others visiting Boston do the same.
Points I’d re-emphasize:
1. The Beer is most important! Don’t fool yourself into thinking anything else is more important. Obviously, you can't please everyone but 90%* of the people there would try as many beers as you stuck in their face. So don't be stingy, 4 ten oz pours is a good start. How about a smaller sampler flight with more varieties, because there are going to be people who want to try them all. I.e. Any home brewers Lastly, Can you please make sure there’s enough people on staff, I know people who walked out of Ommegang after waiting 20 mins for their first beer. (*the other 10% being the reluctant ladies we drag there who only drink wine or vodka).
2. Since I know Rohrbachs (better than some of the others), I'd almost say don't bother with the tour (Is the facility really big enough to do a tour? I'm just comparing it to others throughout upstate NY), allow your expert staff to cater to individual group needs by answering any of the questions or interests they may have. And I agree what others have mentioned, sell what makes you unique. New location, New Beers, Unique Recipes (I know the scotch ale is pretty damn tasty), History of the company, etc. Save the mandatory story about ingredients, even my girlfriend who could care less about beer doesn't want to hear it.
3. The F.X. Matt tour is one of the best. Reason's why... Great historical story, cool Victorian buildings, complete tour of the facilities, quick education about process and ingredients, pretty much as many beers as you want, and the staff is always friendly. Also, Utica Club is currently available in select bars From Buffalo to Albany, and throughout the Adirondacks. Historically is was more available during our parents' generation, disappeared for a while, now its making a comeback.
I personally wouldn’t do a tour. At Rohrbach’s size (compared to others who do tours) I would just design a tasting parlor that overlooks brewing operations. But it may be too late for such modifications.
Just my thoughts, many of which are based on the same fun, crazy, beer loving customers whom you’ll be seeing come through your doors. Good luck. Cheers!
