By late summer, the Willamette Valley is practically daring you to preserve something. The tomatoes come in all at once. Blackberries take over every unattended fence line in Lane County. Neighbors leave zucchini on porches like a friendly threat. Whether your haul comes from a backyard garden, a bench at Lane County Farmers Market, or a u-pick farm out toward Junction City, canning is how you keep August on the shelf until February.

Eugene has one of the strongest home-preserving cultures in the country, and we stock our canning aisle at Eugene True Value accordingly. Here is what you need, whether this is your fortieth season or your first.

Start with the right method for the food

There are two kinds of home canning, and the difference matters for safety:

Water bath canning works for high-acid foods: jams, jellies, fruit, pickles, salsa with enough added acid, and tomatoes with a splash of lemon juice. It needs nothing more than a big pot with a rack, like the Graniteware 15.5-quart water bath canner with rack and lid, or the larger CINSA 21.5-quart cold pack canner if you process in big batches.

Pressure canning is required for low-acid foods: green beans, corn, carrots, soups, stocks, and meats. No exceptions; a water bath cannot get low-acid foods hot enough to be safe. The Presto 23-quart aluminum pressure canner is the standard we recommend, and it doubles as a water bath canner, so it is the one-pot answer if you plan to do beans and stock as well as jam.

If you inherited a pressure canner from a parent or grandparent (a very Eugene situation), check the sealing ring and gauge before trusting it. We stock replacement sealing rings and steam gauges for Presto models, and OSU Extension in Lane County tests dial gauges for accuracy; it is worth doing every season or two.

Jars, lids, and the annual lid math

Jars are reusable for decades. Flat lids are not; they seal once. Every fall someone comes in at 8 p.m. mid-batch because they ran short of lids, so count your flats before the tomatoes hit the counter.

We keep the full range of Ball regular-mouth quart jars and wide-mouth pints in stock through the season, plus 8-ounce jelly jars for jam gifts. For replacement flats, grab Ball regular-mouth dome lids or wide-mouth dome lids by the 12-pack.

Wide mouth or regular? Wide-mouth jars are easier to pack (whole tomatoes, pickle spears, pears) and easier to clean. Regular-mouth lids cost a little less and the jars stack slightly better. Most serious canners in town run both.

The small tools that save your knuckles

A jar lifter is not optional; it is the difference between confidently pulling a quart out of boiling water and a very bad afternoon. Ball also makes a secure-grip version that clamps on straight every time. Add a wide funnel and a bubble-remover tool and the whole process gets calmer; we stock the full set of small canning tools in the same aisle.

Pectin, and the low-sugar question

Willamette Valley berries are so sweet that many local canners have moved to low-sugar recipes. Ball RealFruit Low or No-Sugar Pectin sets reliably with a fraction of the sugar of classic recipes, and it is what we suggest for marionberry and blackberry jam. For traditional recipes, Mrs. Wages Home Jell fruit pectin does the job the way your grandmother's did. Pickle people: Ball Pickle Crisp granules keep cucumbers snappy without the old lime-soak step.

A realistic first-timer project

If you have never canned before, do not start with a pressure canner and a bushel of green beans. Start with one batch of blackberry jam: free fruit from any Eugene greenway, six jelly jars, one box of pectin, a water bath pot, and about two hours start to finish. You will hear the lids ping as they seal on the counter, and you will be hooked like the rest of us.

Stock up before the rush

Canning supplies in Eugene move in waves that follow the harvest: berries in August, tomatoes and salsa in September, applesauce and pears into October.
