It can be worth it. For my family, a bunch of tomato plants are the main crop. Every year it means bottling 150-200 quart jars of tomatoes. It is a bunch of work, but they are far more delicious than store bought. The bottles are in food storage for about a year and still taste amazing. We've had others, but tomatoes are the biggest crop. My parent's back yard also had a bunch of fruit trees, peaches, pears, plum, and cherry, with a strawberry patch and even a grape vine. I grew up with those begin bottled as well.
Having all the bottles of tomatoes makes it easy for food prep. All kinds of sauces, soups, and stews require tomatoes, so most dinners for everything from lasagna to chili involve bringing out a bottle or two. Deserts are as simple as a grabbing a bottle of peaches or pears, and we always have a stock of jams and jellies.
This year was the first time in my life we didn't have a garden because we needed to move. Our shelves have been switching from full jars to empty jars, and the grocery bill has been slowly increasing to compensate.
