You have to call in advance to schedule a tour, otherwise you can swing buy during regular business hours to sample and buy their products. I prefer the sweet liqueurs (Likör) to the spirits but all are available for sample and the bottles are very reasonably priced. I got a Nusslikör(nuts) and a Waldmeisterlikör which is based on what we call woodruff in the USA. You're not going to find that in the liquor store. They also have a large selection of small bottles suitable for travel.
