A31

Traditional Scottish brewers yeast strain, well suited for malt forward beers.

Tartan is a traditional strain that accentuates the malt character of Scottish and other malt forward styles. But don't put it in a corner, it can also be used for other styles and works well in IPAs due to its clean fermentation character. For a higher ester profile, use this ale yeast at the top end of the temperature range.

Beer Styles

American Brown Ale
American Brown Ale

A malty but hoppy beer frequently with chocolate and caramel flavors. The hop flavor and aroma complements and enhances the malt rather than clashing with it.

Wee Heavy
Wee Heavy

Rich, malty, dextrinous, and usually caramel-sweet, these beers can give an impression that is suggestive of a dessert. Complex secondary malt and alcohol flavors prevent a one-dimensional quality. Strength and maltiness can vary, but should not be cloying or syrupy.

Red Ale
Red Ale

An amber, hoppy, moderate-strength American craft beer with a caramel malty flavor. The balance can vary quite a bit, with some versions being fairly malty and others being aggressively hoppy. Hoppy and bitter versions should not have clashing flavors with the caramel malt profile.
