Cheese Wash, B. Linens

The brine you wash a washed-rind cheese with — and the recipe exists mainly to correct the commonest failure in that whole family.

🔴 “I washed it faithfully and it never went orange.” The reason is that Brevibacterium linens cannot start. It needs a surface pH of around 5.5, and a cheese leaves the mould at about 4.9. At that acidity the bacterium you are trying to grow simply will not establish, no matter how diligently you wash.

⭐⭐ So the first fortnight of washing is not a B. linens schedule at all — it is a YEAST schedule. Debaryomyces and Geotrichum go on first, eat the lactic acid, and raise the surface pH into the range where B. linens can live. Only then does the orange start.

⚠ Which means a rind that stays white for two weeks is on schedule, not failing — and that is the single most useful thing on this page.

Ingredients

• 1 quart cool unchlorinated water
• 1 oz (about 2 Tbsp) non-iodised salt — for roughly 3% brine
• 1/8 tsp Brevibacterium linens culture
• 1/8 tsp Debaryomyces hansenii, OR Geotrichum candidum — see the directions
• A clean jar with a lid, and a dedicated cloth

Directions

Key ingredients

Salt

1. Boil the water and let it cool completely. Chlorine kills what you are trying to grow, so use unchlorinated water or leave it out overnight first.
2. Dissolve the salt to about 3% — 1 oz per quart. ⚠ Stronger is not better. Above roughly 5% you start inhibiting the very organisms you are cultivating; below about 2% you invite everything else.
3. 🔴 Add the YEAST first, and give it a head start. Stir in the Debaryomyces or Geotrichum, put the lid on, and leave the jar at room temperature for 12 to 24 hours before you use it. ⭐ This is the step that makes the difference — you are inoculating the wash with the organism that has to work first.
4. Add the B. linens at the same time, and stop worrying about it for a fortnight. It is in there waiting for conditions it cannot yet survive.
5. To wash: wring a clean cloth out in the brine and wipe the whole surface, firmly enough to spread what is growing, gently enough not to tear the young rind. ⚠ Damp, not soaked — a wet cheese in a humid cave grows the wrong things.
6. Wash on a schedule and keep to it: every 2 to 3 days for the first three weeks, then weekly. Cave at 55 F / 13 C and 90-95% RH.
7. ⭐ What you should actually see, in order: white and slightly tacky for the first week or two as the yeast establishes; then pale cream; then pink; then the orange-tan and genuinely sticky rind you were after, usually somewhere between weeks three and five.
8. Keep the jar in the fridge between washes and make a fresh batch every month or so.

Notes

Where this recipe came from — and what it is not ⚠ UNTESTED as written. I have not made a washed rind — that page says so outright — so this is the standard formulation with the reasoning attached rather than a transcript of my bench.

🔴 The finding, and why no home guide states it Most instructions say wash the rind every few days with a 3% brine and B. linens. That is not wrong, but it leaves out the sequence, and the sequence is the whole thing: the bacterium cannot colonise the surface it is being applied to until something else has changed that surface. ⭐ A washed rind is a two-organism succession, and the first organism is a yeast.

⚠ So the diagnosis for “it never went orange” is usually one of three things, and none of them is not enough washing: no yeast in the wash at all; too much salt, which suppressed the succession; or giving up at two weeks, when the cheese was doing exactly what it should.

⭐ Where this is used Cheese, Taleggio-Style · Cheese, Morbier-Style · Cheese, Reblochon-Style · Cheese, Limburger · Cheese, Herve-Style — and a lighter version on Cheese, Gruyère-Style, which carries a real washed rind under all that alpine reputation.
