Beer Production

The data this week comes from the Alcohol and Tobacco Tax and Trade Bureau (TTB). H/t to Bart Watson for sharing the source of the data.

There's a literal treasure trove of data here:

• State-level beer production by year (2008-2019)
• Number of brewers by production size by year (2008-2019)
• Monthly beer stats aggregated across the US (2008-2019)

Some considerations:

• A barrel of beer for this data is 31 gallons
• Most data is in barrels removed/taxed or produced
• Removals = "Total barrels removed subject to tax by the breweries comprising the named strata of data", essentially how much was produced and removed for consumption.
• A LOT of data came from PDFs - I included all the code I used to grab data and tidy it up, take a peek and try out your own mechanism for getting the tables out.

Massive shoutout to pdftools by ROpenSci and stringr for doing a lot of heavy lifting with the datacleaning and prep here.
