I made a batch of ale and bottled it with two kinds of bottles--capped Sierra Nevada bottles, and Grolsch-style swing-cap bottles. The beer in the capped bottles is pale (I used pilsner malt), clear, and nicely carbonated, while the beer in the swing-cap bottles is darker, murky, and rather flat. The obvious conclusion is that swing-cap bottles aren't making a good seal, but they're new, and the spring seems tight. I also don't know why that would change the color of the beer. Any ideas?
