Official whiskey price survey

We are gradually accumulating whiskey pricing data in the Meet My Shorts column. The state Central Statistics Office has been doing something similar for Dublin and the rest of the country. According to their findings:

• A bottle of whiskey (take home) is 2.7% more expensive in Dublin than outside Dublin.
• A single measure of whiskey is 6.9% more expensive in Dublin.
• A bottle of whiskey in Dublin varies between €23.89 and €27.54, average €26.04.
• A measure of whiskey in Dublin varies between €3.48 and €4.27, average €3.89.
• A bottle of whiskey outside Dublin varies between €19.10 and €27.39, average €25.36.
• A measure of whiskey outside Dublin varies between €3.22 and €4.29, average €3.64.

For a measure of whiskey, those Dublin figures seem on the low side to me. Maybe I'm hanging out in the expensive bars.
