ATF Roggenbier - Grainfather

Roggenbier translates to “Rye Beer". It is typically 50% Rye malt giving it a characteristic grainy spicy character, which is completed by the classic weizen yeast tartness, spicy clove phenolics and fruity banana esters. With hints of dark stone fruit and caramel flavours it is great Autumn and Winter wheat beer, but due to its medium dry to dry finish it is drinkable all year round.

Yeast is not included in the kit. We recommend using Lalbrew Munich Classic or Mangrove Jack's Bavarian Wheat yeast.

Note on Rye Malt

Rye malt contains a high amount of beta glucan, which increases wort viscosity and may slow runoff during lautering and sparging, and potentially cause a stuck sparge.

A mash rest at 40℃, sometimes called a Beta Glucanase rest, can help to break down the beta glucan in the wort and reduce the risk of a stuck sparge.

As added insurance this recipe includes oat hulls in the mash. The oat hulls do not add any fermentables, but improve the filter bed of the mash to reduce the risk of a stuck sparge.

Note on Mash Schedule

The recommended mash schedule for this recipe is based on using Fermentis SafAle WB-06. If using a different yeast you may need to adjust the mash schedule.
