Looking for a little help from anyone who has used an oak spiral. I purchased an oak spiral with medium plus toast from farmhouse brewing. Planning on doing a English bitter and then age it on the spiral. How long would you recommend letting the spiral sit in the secondary? I'm looking for the oak aroma and a light taste of oak in the beer, nothing overwhelming. If anyone has had Two Brothers Long Haul Session Ale, that's kinda what I'm shooting for.
