Beer instead of Seltzer in tempura? I have a tempura recipe I want to try, however it calls for "Very cold seltzer". Since I'm not a fan of seltzer normally, I don't have any on hand. However, I do have a bottle of beer left from when I made Beer-batter fish. Can I use "very cold beer" in lieu of "very cold seltzer"? Will it alter the texture and taste of the tempura too much?

Thanks!
It will produce the same effect, however it might alter the taste (depending on the type of beer), and will almost certainly alter the color of the final product, as beer contains sugars that will increase browning.
