Israeli customs law dictates rather strict limits on how much alcohol and tobacco you are allowed to bring into the country, duty free. 2 bottles of liquer is the limit, I believe, and a similarly restrictive amount of cigarettes. British customs, however, take a slightly more liberal approach:

Look at the fine print. A customs officer may stop you if you look suspicious, like carrying 110 liters of beer. 100 liters of beer? Perfectly normal. Move right along. Nothing to see here.
