Aside from keeping out of light obviously. Special glass? Certain hops? As much as I like craft beer which is pretty much always in brown bottles, I still enjoy micro malt liquor in 40 oz bottles. While I would prefer that they use brown bottles, I admit it's kind of cool to see what you're drinking, especially when the bottle is nice and frosty cold. Typically I get my 40 ounce bottles from this one store that has them stacked in boxes. Even if there's an open box I'll just open up a new one and nobody ever says anything. Then as soon as I pull the bottles out of the boxes, I stick them in an empty box ( because this place does not have any plastic bags) then cover it up good and make sure its kept away from light until I'm ready to drink it. I haven't had a skunked bottle from there yet. For those who live in the lower New York area, the store I'm referring to Flair Beverage in Northern Manhattan. However, getting a bottle from any other retail store is a risk. A couple of weeks ago I bought a 40 of Colt 45 from the gas station and halfway through it was Pepe Le Pew. What say you? And please don't give me this speech about how "bad" macro malt liquor is, or how you'd rather drink water instead. I know it's not high quality stuff. Thanks.
