I currently have a solera that is over a year old and the beer is very cherry.
You may have seen the thread.... Just add it and let it work, my addition
was made after primary fermentation had taken place and I also added a
couple bottles of Avery Depucluese (sp?) dregshttp://www.homebrewersassociation.org/forum/index.php?topic=1746.0
Temperature range should be on Wyeast site...http://www.wyeastlab.com/hb_yeaststrain_detail.cfm?ID=147
Also If you are not fearful of the fruit, you should consider adding
sour pie cherries canned in water, and or fresh fruit. I also added
and suggest for that extra authentic element an addition of mahleb.
Good luck...sweet sweet cherry pie....
