By and large, most of Lazy Magnolia's beers are going to be somewhat light in body, even their porter and stout compared to most other examples of those styles. These guys know their market and are catering to it. They offer the following beers:
If you want an easy drinking beer for a hot afternoon, then I'd go with their Indian Summer, a spiced American Pale Wheat Ale, Southern Gold, an American blonde. The Southern Gold is probably the closest to what you are looking for.
If you want to expand your tastes a bit try the Reb Ale, an American Pale Ale which is going to be a bit more hop forward but not in your face bitter like an IPA. If it seems too bitter for you, let it warm up a bit and try again, cooler temperatures tend to exaggerate hop bitterness.
My personal favorite is Southern Pecan, its an American Brown Ale which is quite nutty with hints of caramel and toffee as well. This one is easy drinking, a bit sweet on the palate and goes great with steak or any other carmelized meat.
Jefferson stout is their darkest beer, but that doesn't necessarily equate to a heavy body, as this one is fairly thin for an Cream Stout. Think Guinness but not nearly as dry. Flavor is that of coffee, roasted malt and a hint of sweet potato. Not my favorite stout by any means but it would make a good gateway beer for the uninitiated craft beer drinker.
Their last beer is Gulf Porter. This one only comes in half gallon growlers. It is an English Porter which is very similar to Stouts but tend to be more subtle in flavor with much less roasted malt astringency. Again, body on this one is on the thin side.
Overall, their beers are pretty good, not world beaters by any means but still very good compared to other offerings in MS and perfect for this emerging market. If you call up the brewery they can tell you where to closest location is that sells their brew in both bottle and party pig (the name for those self dispensing mini kegs you are talking about) formats. Give them a shot, you may be surprised. If you try something and don't like it. Try coming back to it sometime later as certain beer styles are acquired tastes.
