Our neighbor made blackberry jam for us, so we were wondering what the shelf life is?

For best quality, it is recommended that all home-canned foods be used within a year. A typical full-sugar fruit jam or jelly should be safe to eat if the jar seal remains intact and the product shows no visible signs of spoilage from molds or yeasts. Some jams and jellies may have a shorter shelf life than others for optimum quality. For example, lighter-colored jams and jellies may noticeably darken faster than others and not remain appealing for a whole year. Though this is not a safety concern, it may reduce the visual appeal of the product for many people. The type of fruit used will also affect other quality characteristics over time.
Opened home-canned jams and jellies should be kept in the refrigerator at 40°F or lower. “Regular” – or pectin-added, full-sugar – cooked jams and jellies are best stored for 1 month in the refrigerator after opening.

Sugar is a better preservative than any modern substance although it varies from manufacturer. Tate and Lyle cane sugar seems to preserve better than Silver Spoon beet sugar. Unopened jars do NOT need to be frozen and should not be. They will be fine in a cool dark cupboard for years. Once opened it can help to keep them in the fridge particularly in summer but it's not essential. Use common sense. If the jam looks and tastes ok then it is. If it gets a bit of mould on the surface (which is unlikely if it's been prepared properly) it can be removed with some of the jam underneath. The rest of the jar will be ok. Very old jam can get past it's best and this can be seen with the colour being not as bright as it should be and the jam being very stiff to spread.
