High proof bourbons are almost as popular as any bottle bearing the Weller name. So the latest addition to the wheated bourbon line could become almost as scarce as their esteemed Van Winkle cousins. Weller Full Proof clocks in at 114 proof, making it the strongest Weller outside of the Antique Collection release. The bourbon forgoes the chill filtration process many endure, which helps preserve the naturally occurring residual oils and flavors. It might not be as pretty in your glass, but the bump in flavor should be more than worth the trade-off. Buffalo Trace is releasing Weller Full Proof once per year in limited quantities.
