I will be visiting Madrid in several weeks. I have an extra bag that collapses into my main bag that I can use to bring stuff home with me. I have figured out that I have about 15 to 18 pounds left in my baggage allowance upon my return. I plan on stuffing the whole thing with La Casera . (I can get Machego, pimenton, Spanish wine and conservas in Minneapolis!)

My question is-Should I go with the liters,
1/2 liters or the 2 liters? Or should I mix them up? Maybe some cans?
