Final answer:
Guinness Stout, which is brewed exclusively in Dublin to preserve its taste, is likely available on draft and by bottle worldwide because it's shipped globally instead of being bottled locally.
Step-by-step explanation:
The availability of beer on both draft and by bottle can vary depending on the establishment's offerings. In the specific case of Guinness Stout, it is a beer that has a distinct production and distribution method. Unlike other major beer companies that choose to bottle their beer locally in various regions, Guinness Stout is exclusively brewed in Dublin, Ireland. This decision is made to preserve the unique taste that is associated with Guinness. Therefore, in locations around the world, Guinness Stout is likely available in both draft and bottled forms due to its global shipping approach rather than local bottling.
