To clarify a bit, my only experience with the Sun Bear series is with the 2022 Mountain Flower, and this year's 2023 Tupelo.
Last year's Mountain Flower had a tin note of blueberry muffins. A wonderful aroma that translated to the smoke for me. I found it to be very floral tasting and I very much got that fruity, berry taste consistently throughout the first half of a bowl. A nice smoke but one I only reach for occasionally.
This year's Tupelo release has less floral notes, but more of a rich, creamy sweetness. I've only had five bowls which is much too little to form a real opinion, but my first impressions are such that I may like this year's release a bit more.
I find them both enjoyable and have been smoking one or the other almost daily. I do find them to be a pleasant summertime smoke but feel that they could be enjoyed anytime, regardless of the season.
