Went out with some friends last night for an Indian meal. While I'm not generally a beer drinker, wine with spicy food is not something I enjoy so I ordered a pint of Cobra. Within some 5 minutes my eyes were itching like hell and I had all the classic symptoms of hay fever. Apparently Cobra contains four varieties of hops and I guess they infuse the beer with pollen.
Had something spicy and the symptoms immediately abated, but on ordering another beer they returned.
