I have brewed this recipe multiple times and has always turned out great, well balanced with bitterness, flavor and aroma. This time it is showing low IBU's even though I used same hop schedule and amounts. IBU calculation shows 72 but tastes like a beer with 35 IBU's. Centennial for bittering 60 min (1.6 oz.), Amarillo and Citra (.25 oz each at 20 and 5 minutes), then Cascade (2 oz.), Citra (.5 oz.), Amarillo (.5 oz.) and Centennial (.4 oz) at whirlpool
Total 6 oz hops to 5.5 gallon batch 1.062 OG finished at 1.012
What can I do to increase hop presence before serving this Friday evening? Any suggestions appreciated!!
