I edited/rewrote my original review to better compare the Mac Barn version to the current STG one.
MacBaren St. Bruno Flake:
The Virginias are slightly grassy, rather earthy and woody with some tart and tangy citrus, bread, light sugar and floralness, a pinch of spice, and some stewed tangy dark fruit, which indicates bright and dark Virginias were used. I notice the properties of the dark Va. more. The dark fired Kentucky has some wood, earth, floralness, herbs, vegetation, dry sour and light spicy sweetness to go along with a little boldness as an important support player. The rich floral toppings are rose geranium and tonquin, but while the toppings do tone down the tobaccos to some extent, you won’t miss out on what the varietals have to offer. There's a vinegar preservative, but it doesn't translate to the taste. The strength, taste and nic-hit are medium. Won’t bite even if you’re puffing like a steam engine. Has a few rough notes. The flakes are easily manipulated to suit your preference. They may need a light dry time, though I did not do that for this review. Burns cool and clean at a slow to moderate rate with a smooth, very consistent sweet, fruity, rather floral, herbal, mildly sour, smokey barbecue flavor to the finish. Has no dull, weak, or harsh spots. Leaves little moisture in the bowl. Requires some relights. Has a very pleasantly lingering after taste and a pleasant to tolerable sweet, floral room note. Easily repeatable during your smoking day although I do not recommend a big bowl for this blend. Will ghost a briar and a meer in time. Four stars out of four.
9-30-2016: Having very recently smoked the 1980s version, I would say that there are a few differences between the two vintages. The flakes were much longer.The older version has a stronger, deeper rose geranium topping. The tonquin was a tad stronger, and a little deeper. The tobacco flavors also have more depth, and a little more earth and wood. The taste is essentially the same otherwise.

STG St. Bruno Flake:
The dark fired Kentucky provides an abundance of floralness, sweet barbecue, smoke, spice, bread, wood, herbs, vegetation, earth, and mild sourness as the lead component. It’s a lot stronger than earlier productions. The Virginias add a liitle tart citrus, floralness, bitter sour lemon, bread, vegetative grass/hay, spice, acidity, sugar, light earth, and wood. No dark fruit or stewed fruit notes are currently present. The youthful bright Virginia overtakes whatever other Virginia may be present. I suspect that it’s orange Va. They offer a little more than secondary support which is less than past versions when bright Va. did not lead. The DFK used is also responsible for that difference. The rich tonquin and rose geranium toppings are similar to the older version though not quite the same. I notice the tonquin a little more than the rose geranium which is the reverse of the Mac Baren SBF. They also have a mildly higher impact on the overall flavor. I also detect a vinegar note from the casing. The strength and taste levels are stronger now. I rate the former at a step below strong and the latter a tad more than full. The nic-hit is a step past the center of medium to strong. No chance of bite, but unlike before, has a harsh note if puffed beyond a moderate pace. Has a little roughness; lightly more than before. The flakes are rather moist although I did not dry them for review. Your mileage may vary on this point. Deeply rich, it burns clean, fairly cool and slow with a very consistent floral, sweet and sour, barbecue, fruity, herbal, moderately smoky, spicy, acidic, bitter, savory flavor that extends to the long lasting after taste. The strong floral, sweet mildly spicy room notes have some pungency. Leaves little moisture in the bowl and requires a few relights. Not an all day smoke, but it is repeatable. I recommend a medium size pipe at most. Will ghost a briar and a meer. Two and a half stars out of four.
