Firestone Walker Double Jack A dangerously drinkable Double IPA. Double Jack opens up with bright grapefruit and tangerine American hop aromas. Beautifully crafted undertones of stone fruit are revealed upon first sip, followed by the essence of blue basil and pine. A sturdy pale and crystal malt backbone brings balance to high hop intensity. Complex and aggressively hopped, and flawlessly balanced. ABV: 9.5%
