GuidesBy LAVA AustraliaPublished Updated 4 min read

The short answer

  • No more freezer burn, longer shelf life, and buying in bulk that pays off.
  • Meal prep, marinating and sous vide get easier.
  • Fish, game, dry aging, coffee, jars and the garden glut each have their own use.
  • A well-built sealer lasts for decades, so it pays for itself many times over.

Nine reasons

  • 1 · No more freezer burn Without air in the bag, ice can't form on the food's surface. Freezer burn
  • 2 · Weeks, not days Beef keeps 30–40 days in the fridge sealed instead of 3–4 (LAVA's figures). How long does vacuum-sealed meat keep?
  • 3 · Buying in bulk pays off Family packs and specials, portioned and sealed. A sealer in the household
  • 4 · Meal prep Cook once, freeze flat in portions, eat well on busy nights. Meal prep
  • 5 · Marinating The marinade on every surface, with less of it and no mess. Vacuum marinating
  • 6 · Sous vide Sealed food cooks evenly in the water bath. Cooking times
  • 7 · Fish and game The catch or the harvest, sealed the same day. Fish · Game meat
  • 8 · Dry aging at home With breathable dry-aging bags, in the normal fridge. Home dry-aging
  • 9 · Coffee, jars and the garden Containers and jars vacuumed through the hose; vegetables kept for months. Coffee · Summer vegetables

And a tenth: it lasts

A sealer is used for years, so build quality matters more than the price on the day. LAVA sealers are built to be repaired rather than replaced, with spare parts supplied for 20 years. What to know before buying a vacuum sealer
