Raspberry Sour Ale Brewed with Amoretti Natural Flavor

Today we are talking about a very special recipe, born from the collaboration between ThePilotBeer and Amoretti. Amoretti is a Californian company that produces high quality natural extracts and flavors and are the most popular fruit and dessert extracts among brewers. The basis of our recipe is a Kettle Sour Ale and the grain bill is pretty simple: Pale ale, Pilsner and Wheat malts. The hop addition is also light. The real stars of this beer are: acidity and the addition of raspberry extract. Their combination results in a perfectly balanced beer, where the sweetness of the fruit pairs perfectly with the acidity of the Kettle Souring process.

Mash Steps

  • 68 °C/152 °F for 60 mins
  • 77 °C/170 °F for 15 mins

Kettle Souring

After the mash process and a short boil (15 mins) to sterilize, chill the wort to 37 °C (98 °F) and add 1 kg of unmilled Pale Ale malt to the kettle. Keep the temperature of 37 °C/98 °F for 48 hours. The PH, after 48 hours of soaked malt, is 3.8. Now start the boil and add the hops like a standard brew day. Chill the wort and pitch your favorite yeast strain.   

Fermentation Process

We used CCYeastLab's Kveik yeast. Fermented for 7 days at 23C degrees, then raises the temperature for 48 hours for the diacetyl rest. Lower the temp to 12C degrees for 48 hours. Then transfer the beer to the kegs, add the Amoretti Raspberry and wait two weeks, until the natural carbonation is completed.


Final Impressions

A delicious Raspberry Sour Ale with good acidity combined with an intense aroma of freshly picked raspberry (the aroma is amazing!). The yeast helps with a nice tropical fruit flavor to complement the beer profile. Can't wait to put the other Amoretti fruit extracts to the test in different sour beers!
