I had a few more watermelon wheats. the other day with my brother in law.
The beer was bottled on July 2 and had an easily recognizable watermelon taste and aroma two weeks later. If you read above, I served it Aug 3 at a party and it was very well received with everyone easily percieving the watermelon. However, I thought that the taste was a bit more subdued than it was at a mid July tasting.
Three weeks later I can definetly say that the watermelon 'essence' of this brew has mellowed with age. It is still a light, drinkable beer, but the wallop of watermelon that used to be there is greatly subdued.
I don't know it it is related to the all-wheat beer recipe I used to carry the watermelon, or if it something that just happens to the watermelon flavor. A pale-ale type recipe may offer different results. Based on my experience, this seems like a great beer to drink while its young. Drink 'em if ya got 'em!
