Species: Saccharomyces cerevisiae var. diastaticus

Profile: The classic choice for brewing golden strong ales. This alcohol tolerant strain will produce a complex ester profile balanced nicely with subtle phenolics. Malt flavors and aromas will remain even with a well attenuated dry, tart finish. This strain is prone to stalling at approximately 1.035; racking or slight aeration will encourage it to finish fermentation.

Metric Temperature Range: 18-27 °C

Notes: This Wyeast yeast strain has been classified as Saccharomyces cerevisiae var. diastaticus using rapid PCR analysis. This strain carries the STA1 gene, which is the “signature” gene of Saccharomyces cerevisiae var. diastaticus and will be found in all diastaticus strains.

FLOCCULATION: Low
ATTENUATION: 74 - 78
ABV: 12

IN-STOCK YEAST: We maintain stock of high-selling liquid yeasts in the shop, to make it easy for anyone who needs liquid yeast in a hurry. These will always be sold within the best before date. If a strain is out of stock, then it won't show up as an option for you to purchase. If you want the freshest liquid yeast, or if we are out of stock, consider using the pre-order option. Pre-ordered yeasts are ordered directly from the manufacturer on your behalf and we do not use in-stock yeast to fulfil pre-orders.

PREORDER DEADLINE: Every 2 months we place a liquid yeast order with Wyeast. All pre-orders placed will be part of our next order from the supplier, subject to the supplier having your pre-ordered strain in stock.

We place our orders on or after the 20th of the month. The deadline to ensure your pre-order is included is midnight the day before.

All pre-orders will be available for pickup or shipping after we receive the yeast which is usually around the first week of the month.

*Note: we will ship your order when your yeast arrives, so if you wish to place an order for other items and want to receive them sooner, please place a separate order.

ORDER SCHEDULE: We will place an order for Wyeast in January, March, May, July, September and November.
