Bottles old the flavor better, but there are a lot of advantages to tinned (canned) beer, such as;
1. If you drop it, it probably won't break. Might turn into a fountain when you open it, but it won't break.
2. You can get more tins than bottles into your panniers (saddle bags).
3. You can't flatten a bottle and put under your sidestand when parking on soft stuff.
4. You can't flatten empty bottles to make the rubbish bin hold more.
