A couple basic guidelines:
The less hops the better, as hops are the mouth of injustice (Tehillim 107:42):
וְכָל-עַוְלָה, קָפְצָה פִּיהָ
All injustice, hops are its mouth
Imported beer seems to be a good choice, as our ancestor Rachel was consoled by the news that her employees were bringing back beer from enemy lands (Yirmiyahu 31:15):
מנעי קולך מבכי, ועינייך, מדמעה: כי יש שכר לפעולתך נאום-יהוה, ושבו מארץ אויב
Refrain your voice from crying and your eyes from tears, for your employees have beer, says the Lord, and they are returning from enemy lands.
