Lallemand LalBrew Diamond™ · Dry Lager Yeast · 11 g

Lager that tastes like lager. Diamond is a true German lager strain — neutral, clean and quick to settle — for everything from Bohemian pilsner to doppelbock.

Attenuation 77–83 % · 10–15 °C · High flocculation · Neutral · 100–200 g/hl · 11 g sachet

What it does in your beer

LalBrew Diamond™ is a true lager strain (Saccharomyces pastorianus, Group II / Frohberg lineage) selected from the Doemens Academy Culture Collection in Germany. Flavour and aroma are neutral, typical of traditional lagers, and it's POF negative.

Attenuation is 77–83 % with high flocculation. At 10–15 °C, fermentation can be complete in about 7 days, and 13 % ABV tolerance leaves room for bocks and eisbocks.

How much for a 20 L batch

Lallemand's rate for Diamond is 100–200 g/hl — double its usual ale rate. For 20 L (0.2 hl) that's 20–40 g, i.e. 2–4 sachets (approx.: dosage × 0.2 hl, rounded up to whole 11 g sachets).

High-gravity, high-adjunct or high-acidity worts may need even more yeast plus extra nutrients, according to Lallemand.

How to use

• Dry pitch (preferred): sprinkle all the sachets evenly over the wort as the fermenter fills.
• Rehydrate only if dry pitching doesn't suit your kit: 10× the yeast's weight of clean, sterilised water at 30–35 °C, 15 minutes, a gentle stir, 5 minutes, then attemperate in steps of no more than 10 °C every 5 minutes. A 30 °C slurry heading into 12 °C wort needs two steps. No distilled or RO water.
• Ferment at 10–15 °C.
• Re-pitching is possible — aerate the wort when you do (Lallemand).
• Pack lost its vacuum? Don't use it.
