Just to update:
I added 420 grams (+/- 1 pound) of frozen raspberries to my primary (after pasteurizing at 170°F for 10+ minutes).
Here's the recipe:
1.5kg LME (Munton's Irish Stout)
1kg DME black Malt
1kg DME Dark Malt
1/2 oz Cascade (boil)
1/2 oz Fuggles (10 mins)
420g frozen raspberries, pasteurized at 170°F for 10+ minutes (added straight to fermenter filled with 15 liters chilled brewing water, then chilled high-gravity wort added)
Safeale S-04 yeast (dry)
Fermentation kicked off after 4 hours (!!!)
Yield : 23.5 litres
Status : Still fermenting.. Can't wait
