The kit comes with pieces of barrel staves, about 2 oz. IIRC. There were 5 pieces approximately 1/5" thick. The inside of the stave had a wine ring that had penetrated into the wood maybe 3/8", so very little actual wine with the kit. However, I took a growler of mine to our club meeting the other night and most people commented on the "red wine" character.
I left my kit on the oak for 2 months and to me it's very similar to Consecration. Tartness is less in mine, and measurable with a .2 pH difference. Other than that it's very close to the real thing.
BTW, at room temp. using Abbey Ale II, mine went to 1.012 very quickly. I then added the currants, and Roselare along with a quart of starter wort into a fermentation pail overnight before racking the beer the next morning. That may not have been necessary, but it seemed like the thing to do at the time.
