Summery beers question?

Good beers are best enjoyed in the summer.  Nothing goes down better than a cold one on a hot summer day.  My personal favourites would include...

Red Stripe

Bud Light Lime (it's not for everyone)

Moosehead

Corona Extra

Molson Canadian

Heineken

NOTE:  Beer should always be poured into a chilled glass (cold tap water is chilled enough), and wait for the big bubbles to stop rising before drinking it.  The little micro-bubbles are okay.  I got this tip from a real live German braumeister (master brewer) who worked at Coors Molson, and it works.  It makes every beer smoother and cleaner tasting.

Shandy screams hot summer day. Your lighter beers (kolsch), anything made with fruit are also summer classics.

Winchester Blue Berry ale

Sam Adams summer ale

Kinroo blue Belgian white ale

Kinroo blue blond ale

Shandies, lemon-infused beers, are considered a summer drink.

Shandies are always great for summer. I don't know if you're a fruit beer kind of person. 

You said nothing about what kind of flavor you want.

Consider a citrus IPA, although beware that lower quality ones can taste like soap.   One of my favorites is a grapefruit IPA called Citrus Mistress brewed by Hop Valley in Oregon. 

Just so you know, IPAs have a lot of hops and therefore are not meant to be sweet.  They have a clean, crisp flavor, are not heavy like a wheat beer, porter or stout, but they are refreshing on a hot day despite their bitterness.   They do tend to have a higher alcohol content than a regular beer so beware if you're a lightweight.
