I'm going to take this into serious consideration. The more I read on this I've been hearing about flavor & ester loss with the pasturizing process and since she's wanting big raspberry flavor & smell this may be a better alternative.
maceration is a wonderful process that gets us many nice things such as limoncello. Neutral grain liquors over 50% do a wonderful job pulling the essential oils and flavors out of things, which is why i use them very often as my flavor additives into the secondary. Some people state that it gives the beer a fake or artificial taste, but when you do the maceration yourself, I have to disagree.
You can choose to make a tincture (let the alcohol macerate the ingredient for 3-4 weeks, discard the ingredient) and add that to the secondary, or if you want to macerate the ingredient and also use it in the secondary, macerate for 30 mins and make sure to also dump the alcohol you used for the process into the secondary as well. A tremendous amount of the ingredient your macerating will be in the alcohol, even after only sitting for 30 mins. Its worth it!
