We paid extra for the Connoisseur Class, which I HIGHLY recommend! The storehouse tour is included and is informative and fun, but it's huge and crowded and feels a bit impersonal. You also get your free pint at the Gravity Bar up top, which is beautiful but, again, pretty crowded. The Connoisseur Class is limited to about 12 people at a time, and they take you up to a private bar on the 4th floor, where you spend an hour with your personal host tasting varieties of Guinness and learning about the history of the beer, Dublin, and anything else you want to ask. We also learned how to pull a proper pint of Guinness ourselves! Our host was Kevin, and he was a delight! So fun, knowledgeable, and friendly. He quickly made us all feel right at home and made our class one of the highlights of our Ireland trip. We loved the intimate, personal feel of that experience and would highly recommend splashing out the extra cash to do it.
