Bujapat,
That was three questions.
I wish I could age my stuff more than one month...

However, even in that short time, UJ's sourmash is ambrosia. Now that I've got a bigger batch going, I hope I'll be able to keep from drinking it so quickly... and manage to keep some for longer aging.
I havent managed to keep ANYTHING longer than a month... I know, I know, I sound like an alcoholic, but when the stuff is soooooo good, and you've got visitors every weekend, it seems to go quickly.
Anyway. I usually use about 5-6 strips per 2.5-3 liters (I soak in 3 liter glass jars). I also add (sometimes) 5-6 peppercorns and sometimes 4-5 cilantro seeds. For my fruit brandys, I also add a shot of raisings (if I feel like making a sweet brandy).
I age everything at 40%. (Again, knowing myself, I know that I'm going to want to taste it during ageing, so if I aged it at a higher proof, I'd have to dillute every time I cheat...

)
By the way where in Belgium do you live? I travel to Brussels every once in a while...
