The instructions that come with wine kitshave you add all the oak during primary fermentation. It never has you save any back. Assuming no additional oak is added,I am curious to know if most follow that recommendation or do you often save some or all of the oak for secondary fermentation or bulk aging. With oak shavings I would always assumebest in primary because of the fast extraction but some only come with chips. 1-2 weeks isn't very long to extract the oak. I have a RJS EP Amarone in secondary right now after 14 days in primary. I placed all the oak in the primary. I'll taste on next transfer and add more if needed but just wondering.
