Hi all,
I've been a Type 1 diabetic (and drinker) for a long time.
1. All Alcohol lowers blood sugar
2. Some alcoholic drinks have a greater amount of residual sugar (which raises blood sugar)
3. The more alcoholic the drink (aside from alco pops) typically the more your blood sugar will decrease (more residual sugar in the drink is converted to alcohol)
From my experiences:
1. Pure Spirits (such as whisky, gin & vodka) lower blood sugar.
2. Red & White wine (especially those around 12-14%) lower blood sugar.
3. Strong Lager (around 5%) usually keeps blood sugars level.
4. Weak Beer usually increase blood sugar.
5. Ales & Stouts (especially boutique real ales) are the most difficult, some strong brews still raise sugar levels and some weak ales lower sugar leves (it depends on the residual sugar which is more variable according to the taste the brewer wishes to create).
Usually I try and snack with spirits and wine, not eat with strong beer and when I drink weak beer I check my sugar levels and have additional injections as necessary.
Please note this regieme may not be the most suitable routine for you.
Typically if you drink the same drink for a while, you will learn how it affects you at different times of the day.
