Casings 101 for New Home Butchers

Oct 31, 2025Cameron Baker

If you’re making your own sausages, the casing you choose decides the bite, the look, and how well your links behave on the pan or grill.

The sausage casing families: 

1.      Natural (sheep, hog, beef/ox) – edible
Cleaned animal casing. Great flavour carry, lovely snap, excellent twist strength.

·         Sheep: slim, delicate sausages with a fine bite.

·         Hog: everyday “Aussie BBQ” style sausages.

·         Beef/Ox: salamis and other continental style sausages.

2.      Collagen – edible
Made from beef hide collagen. Edible versions are tidy and consistent; Easy to handle and the size is quite accurate.

3.      Fibrous – nonedible
Strong sleeves for salami and big cooked sausages. Tie, hang, cure/smoke/cook, then remove before consuming.

Best-practice tips & tricks:

  1. Prep casings properly.

·         Natural: Rinse off salt, soak in cool water 20–30 mins and flush the inside.

·         Collagen: Usually used dry. Check the packet.

·         Fibrous: Dry and ready to load; don’t eat them.

  1. Match grind to casing size.
    Finer grind for slim sheep; a coarser grind is better for hog.
  2. Don’t over-fill.
    Firm is good; to tight and the casing blows out and won’t twist properly.
  3. Twist gently and evenly.
    Natural casings handle firmer twists; collagen prefers a lighter touch.
  4. Prick bubbles.
    A quick pin prick lets trapped air out, so sausages don’t balloon on heat.
  5. Storing leftover sausage casings.

·         Natural: back into heavy salt in the fridge; keep sealed.

·         Collagen/fibrous: cool, dry, away from sun and humidity.

 

Troubleshooting

  • Casing keeps tearing:
    Mix or casings too dry, or you’re over-stuffing. Add a splash of chilled water to the mix and ease the fill.
  • Links won’t twist:
    Too tight or too warm. Loosen the fill slightly and chill the mix longer.
  • Wrinkly after cooking:
    Heat too high at the start or under-filled. Start gentler; finish hotter.
  • Air pockets:
    Slow down the feed, pack the horn fully, and prick bubbles before cooking.
