I like vacuum bagging food. What I like most about doing it is that I can start preparing the food for extended trips, months ahead of time. Also, I can bag perfect portions for my needs, from cereals to vegetables to a few treats. I also dehydrate my supplies. The two processes go hand in glove.
Commercially sold back packers food stuff is just that. I find that they are either too sweet, too chemically after-tasting, too skimpy or just plain horrible to eat. Also you get little value for your money which makes them doubly unsatisfying, I find. Know what I mean?
Eight weeks of supplies for my last cycle/walking tour through the Northern Alps. I like to remain unsupported. You can do a lot when you are well fed and not having to bother about the need to resupply.

The white packets on the left are Indian flat bread mixtures. The pale yellow packets on the right are full cream powdered milk. Last trip I carried double the amount of milk shown in this photo and missing from this image, is a dehydrated 8 kg watermellon. The watermellon was reduced to only 100gms, to virtually being weightless, after dehydrating. 500gm of seeded green olives reduced to 30 gms. I took this shot before I had finished bagging the breakfast cereals (at the top of the table) I also have a telescopic fishing rod and use Celta #2 red and gold lures/spinners and Celta #3 Frog spinners for here in the mountains. I like to cook when I tour.
I like bushwalking with my bike and "V" bagging the grub makes it work well. It is good not carrying the weight.

Warren.
